A biologist measures the allele frequencies of pea plants in a very controlled environment. The plants can either have a dominan
t tall allele (T) or a recessive short allele (t). Which of the following is a reason that this population is not at Hardy-Weinberg equilibrium? A. The pea plants are mated at random.
B. Both alleles ensure equal survival.
C. One pea plant mutates to have a new allele.
D. Every pea plant reproduces exactly once.
Hardy-Weinberg equilibrium refers to the equilibrium of the gene frequencies in a population from generation to generation in the absence of evolutionary influences.
The Hardy-Weinberg assumptions for this equilibrium are:
Random mating
No mutation
No natural selection
No emigration and immigration
Large population size
Thus, the formation of a new allele by mutation would disturb the Hardy-Weinberg equilibrium.
The human brain is divided in to two parts and that is why human brain is responsible for controlling behavior of human and motor control . The sheep have only one portion. Compared to the sheep, the human olfactory bulb is larger in size while the stem on the sheep is larger than human. The cerebellum in the human brain is larger and more secure than the sheep.
