Answer #1

Ans1) A trait that is heritable and increases fitness becomes common in a population of any type of animal or plant.

This Is because if an individual has some form of a trait that gives him a better chance of survival in a given environment, evidently is of spring inherit the trait. This is known as differential survival. Differential survival would refer to the survival of individuals in an environment to which they are well adapted. The adaptations are genetically controlled and heritable. Differential survival leads to a differential reproduction of alleles responsible for the survival of the next generation.

Natural selection means differential reproduction among members of the same gene pool. So natural selection is the non random process by which biological traits become common in a population as a function of the differential reproduction of the bearers or differences in the rate of survival.

    Assignment: Inheritance Background: The images above shows an individual with a common thumb variant (recessive trait) and one with brachydactyly type D (dominant trait). The reduced length and increased girth of the distal phalanx in brachydactyly type D has to do with a mutation on HOXD13 (part of the hoxD gene cluster on Chromosome 2) that effects its pattern of development. Your question: Considering that brachydactyly type D is controlled by a dominant allele, will it replace the common recessive...
