Recessive inheritance occurs only when a person receives two __________ alleles, one from each

1 answer:

7 0

Recessive alleles. Recessive alleles are only expressed phenotypically when the offspring receive recessive genes from each parent. In other words they are only expressed phenotypically when they occur in pairs. In the presence of dominant gene they are never expressed phenotypically and the offsprings with both the recessive and dominant genes occurring concurrently are referred to as carriers.

We can also cross-out A.

Now we have B and D. Commensalism and Mutualism. Now, commensalism is an association between two organisms in which one benefits and the other derives neither benefit nor harm.

Mutualism is the doctrine that mutual dependence is necessary to social well-being.

Did any alleles disappear from your population? if so, why? if not, why not? how does this relate to the most fit phenotype

dmitriy555 [2]

Alleles can disappear from a population through natural selection. This relates to the most fit phenotype because the breed with the desirable trait, or the most fit, will live and produce off spring. Eventually the less desirable trait and its corresponding allele will disappear after multiple generations pass. If the environment does not change alleles of non desirable traits will disappear. <span />
