Question

If all variation among individuals in a population is due to differing genotypes alone, heritability is _____, and the slope of the line used to measure it is _____.A. 50%; 1B. 100%; 1C. 100%; 0.5D. 50%; 0.5E. 0%; 0

Answer 1

Answer:

If all variation among individuals in a population is due to differing genotypes alone, heritability is 100%  and the slope of the line used to measure it is 1.

Explanation:

If the genes play no role in the variation among organisms of a species, then the heritability will be zero percent. Hence, if all the variations among individuals of a population occur due to the differences in the genotype, hence the heritability will be 100%. This is because genes are the hereditary molecules and the genotype of an organism comprises of the different genes present in an organism.

Answer 2

A genetic modification in between individuals or in a population is called genetic variation. While heritability is a measure of genetic variation of the various traits in a population.

The correct answer is:

Option B. 100% ; 1

This can be explained as:

• If in a population variation occurs due to genotype then it will be 100% heritable.

• The slope used for measuring the line would be equal to 1.

• When in a case variation is independent of genes then it will be 0% heritable.

• So, if there is variation in genes then it will be 100% heritable as genes are the hereditary and genetic molecules.

Therefore, genetic variation will be 100% heritable.
