The University of Illinois has been conducting one of the longest selection experiments, begun in 1896 by C.G. Hopkins. Researchers have been selecting for high corn oil content (as measured in % dry mass). Researchers select those plants with the highest corn oil content, and use only those individuals to seed the next generation. Here is a portion of actual data from their experiment:
1899 mean oil content in entire population: 5.65% dry mass
mean oil content of selected plants: 6.30% dry mass
1900 mean of oil content in entire population: 6.10% dry mass
Calculate the heritability of corn oil content (% dry mass). For full credit, show your work, including any equations used.

Answers

Answer 1

Answer:

0.725

Explanation:

This type of question is a concept of Narrow-sense Heritability and Artificial selection used by plant breeds.

So, heritability = R/S

where;

R = response to selection

S = selection differential

S further implies the difference in mean oil content between base population & selected population.

S = 5.65 - 6.30 = 0.65% ( where the negative sign are not regarded)

R implies the difference in mean oil content between the offspring or population after implementation of selection and the base population.

R = 6.10 - 5.65 = 0.45%

Heritability = R/S = 0.45% / 0.6%

= 0.725

Thus; the heritability in the oil content of corn in the given set of population = 0.725.

In dolphins, to have spots on the skin is a recessive trait. One spotted dolphin and one solid gray dolphin have a baby spotted dolphin. Go through the following steps to figure out the genotype of the parent dolphins.

1) what is the genotype of the spotted (recessive) parent?

Answers

Answer:

the spotted parent has the genotype ss

Explanation:

we will use s as the letter when describing the spotted trait.

since spotted is recessive, that parents have to have two little s to have the trait. Since the child also has that, we know that they will have the genotype ss.  the child would have to get a little s from both parents, so the solid parent would have Ss, showing as solid, but still having the gene for spots.

Explanation:

A society uses this sustainable practice because it reduces the amount of carbon dioxide in an area. So, the correct option is (A).

What is Sustainable practice?

Sustainable practices are described as supporting ecological, human and economic health and vitality. Sustainability recognizes which resources are limited. It should be used conservatively and wisely which take into account long-term priorities and consequences of the way resources are used.

Reduce, reuse and recycle are the basic principles of wise use of resource. Natural resources are conserved and protected by deploying these principals by reducing landfill waste, energy consumption and pollution.

Some sustainable practices are:

By reusing paper and plastic bags for shoppingBy opting for paperless documentsBy avoiding disposable kitchen items

Thus, a society uses this sustainable practice because it reduces the amount of carbon dioxide in an area. So, the correct option is (A).

Compare and contrast gradualism and punctuated equilibrium. Provide at least one comparison and one difference in your answer. You may use examples for each if that helps you with answering the question.

Answers

Answer:

Gradualism and punctuated equilibrium both are the process of evolution of species over time. However, the gradualism process involves the evolution that occurred slowly, occurring in small periodic changes in the gene pool over a long period of time. Whereas Punctuated equilibrium takes place there are longer periods of apparent stasis interrupted by the sudden change.

They both help in finding the relative change in evolution rate and assist in the study of the anatomical changes occurred during the evolution in different kind of animals or organisms.

Answer:

Metaphase

Explanation:

Chromosomes line up at the metaphase plate, under strain from the mitotic shaft. The two sister chromatids of every chromosome are caught by microtubules from inverse shaft posts. In metaphase, the shaft has caught every one of the chromosomes and arranged them at the center of the cell, prepared to separate.

Answer:

It is metaphase.

Explanation:

In metaphase (a), the microtubules of the spindle (white) have attached and the chromosomes have lined up on the metaphase plate. During anaphase (b), the sister chromatids are pulled apart and move toward opposite poles of the cell.
