What are some examples of how mutation aides genetic variation?

Why study human genetics? One reason is simply an interest in better understanding ourselves. As a branch of genetics, human genetics concerns itself with what most of us consider to be the most interesting species on earth: Homo sapiens. But our interest in human genetics does not stop at the boundaries of the species, for what we learn about human genetic variation and its sources and transmission inevitably contributes to our understanding of genetics in general, just as the study of variation in other species informs our understanding of our own.

A second reason for studying human genetics is its practical value for human welfare. In this sense, human genetics is more an applied science than a fundamental science. One benefit of studying human genetic variation is the discovery and description of the genetic contribution to many human diseases. This is an increasingly powerful motivation in light of our growing understanding of the contribution that genes make to the development of diseases such as cancer, heart disease, and diabetes. In fact, society has been willing in the past and continues to be willing to pay significant amounts of money for research in this area, primarily because of its perception that such study has enormous potential to improve human health. This perception, and its realization in the discoveries of the past 20 years, have led to a marked increase in the number of people and organizations involved in human genetics.

This second reason for studying human genetics is related to the first. The desire to develop medical practices that can alleviate the suffering associated with human disease has provided strong support to basic research. Many basic biological phenomena have been discovered and described during the course of investigations into particular disease conditions. A classic example is the knowledge about human sex chromosomes that was gained through the study of patients with sex chromosome abnormalities. A more current example is our rapidly increasing understanding of the mechanisms that regulate cell growth and reproduction, understanding that we have gained primarily through a study of genes that, when mutated, increase the risk of cancer.

Likewise, the results of basic research inform and stimulate research into human disease. For example, the development of recombinant DNA techniques (Figure 3) rapidly transformed the study of human genetics, ultimately allowing scientists to study the detailed structure and functions of individual human genes, as well as to manipulate these genes in a variety of previously unimaginable ways.

Describe several types of agal colonies

Although the term algae originally referred to aquatic plants, it is now broadly used to include a number of different groups of unrelated organisms. There are seven divisions of organisms that make up the algae. They are grouped according to the types of pigments they use for photosynthesis, the makeup of their cell walls, the types of carbohydrate compounds they store for energy, and the types of flagella (whiplike structures) they use for movement. The colors of the algae types are due to their particular mixtures of photosynthetic pigments, which typically include a combination of one or more of the green-colored chlorophylls as their primary pigments.

A microbiologist is in the process of classifying a newly discovered organism. Its characteristics include: · eukaryotic · multicellular · reproduces by spores · motile in some stage of its life cycle · decomposer Which type of organism is it most likely to be? club fungus fungus-like protist plant-like protist sac fungus

Based on the characteristics of the new organism discovered by the biologist, it can be concluded that this organism is most likely a fungus-like protist. The organism is a multi-cellular eukaryote who reproduced by the spores and is motile in few stages of the life cycle. Besides all this it is a decomposer. This all characteristics fit the description of a fungus like protist. They are most commonly found on the dead wood, but they also produce spores like the fungi.

Hence, the correct answer is 'fungus-like protist'.

Why might introduction of exotic species disrupt an ecosystem? A. They're struggling to survive and can be disruptive. B. They die quickly and overfeed scavengers. C. There are very few of the organisms present. D. They can outcompete native species.

Answer: D. They can outcompete native species.

Exotic species are the species which are not native to the region to which they are introduced. They can be referred as alien, non indegenous species. These species are introduced either due to human intervention in order to use these species for their own benefit or these species migrate from their native land in search of food and other resources. These species may act as an invasive species, which means they compete with the native population for resources. Therefore, they will disturb the natural biodiversity of the ecosystem.

Hence, exotic species when introduced in an ecosystem they can outcompete native species.

How is an individual palm tree growing in a tropical forest classified organism,population,abiotic,habitat

Answer:

The correct answer is- organism

Explanation:

An organism is an individual who has all the living characteristics. So an organism can be plat, animal, or a microorganism. So here we are talking about an individual palm tree and we know that a palm tree is a plant which has life so palm tree will be classified as an organism.

When many individuals of the same species are present in an area then it is called a population. The area where a population is living is called their habitat. Abiotic factors are the non-living things like air, water, soil. So the correct answer is- organism.

Which could be classified as part of an ecosystem but not part of a community trees,grasses,bacteria,minerals

The correct answer is minerals.

Minerals can be considered as the abiotic factor present in the ecosystem but it cannot be considered as a part of community.

Ecosystem can be defined as the interaction of the biotic (living things) and abiotic factor(non-living things) in which the plants, animals and human beings survive with each other.

Community can be defined as the group of organisms interacting among each other.

Minerals can be a part of ecosystem but not a part of community.

QUESTION POSTED AT 23/02/2020 - 11:30 PM

18. In a species of wild animal, claw size is determined by a combination of two alleles. Allele Q codes for large claws, while allele q codes for small claws. Individuals with a heterozygous genotype possess claws of medium size. Members of the species depend on their claws to be able to burrow in the ground and find food. But in an area where the ground has always been soft, gradual climate change has caused the dirt to become hard and compact. Which statement best predicts the change that will occur in the affected populations? A. Allele q will decrease in frequency. B. Allele q will become dominant to allele Q. C. Allele Q will become dominant to allele q. D. Allele Q will decrease in frequency.

Answer: The correct answer is- A) Allele q will decrease in frequency.

According to the information in the question, allele Q codes for large claws and allele q codes for small claws in a species of wild animal.

This indicates that larger claws will enable the wild animals to burrow more in the ground and find their food. As the change in the climatic conditions caused the dirt on the ground to become hard and compact.

This will result in change in the frequency of allele of the population as allele Q will increase because larger claws will provide more advantage (in context of burrowing) to the animals for getting their food, whereas frequency of q allele will decrease ( as smaller size of claws will not be that beneficial to them in hard and compact ground).

Thus, option A) is the right answer.

Which major change can occur in a small population that is the result of the genetic drift? A. recessive traits always become dominant B. new individuals add their genes to the gene pool C. large changes in allele frequencies can occur in a short time.

The answer is C. large changes in allele frequencies can occur in a short time.

Genetic drift is a change in the frequency of alleles in a population as a result of random sampling of organisms and it decreases genetic variation of the population. In specific circumstances, large and rapid changes in allele frequencies can occur in a short time. The smaller the population, the more susceptible it is to genetic drift.
