The correct answer is E)52
When there is Hardy-Weinberg equilibrium like in this case of a single locus with two alleles denoted A and a with frequencies f(A) = p and f(a) = q, the expected genotype frequencies under random mating are f(AA) = p² for the AA homozygotes, f(aa) = q² for the aa homozygotes, and f(Aa) = 2pq for the heterozygotes. Let's put that A is dominant and a is recessive allele. In Hardy-Weinberg equilibrium we have:
p²+2*p*q+q²= 1 p+q=1 p=1-q
f(a) =0.4=q q²=0.4²=0.16=16%
p= 1-0.4=0.6 p²=0.6²=0.36=36%
Percentage of a homozygous genotype in the population is 16%+36%=52%
Polyploidy is the term that describes the chromosomal abnormality of having extra chromosomes.
Answer:
1. Cohesion is the attractive force between water molecules
Explanation:
Answer:
Sensory transduction
Explanation:
The sensory process involves many steps to send the signals from the receptor to the brain.
In this, the step that is involved in the conversion of the physical energy into the electrical signal at the sensory receptor (in the given case mechanoreceptors) is known as the Sensory transduction.
When the mechanoreceptors get stimulus by the physical force, it opens the mechanical gate of the dendrites which allows the influx of the positive ions. The influx of the positive ions causes depolarization of the membrane which initiates the action potential which is then transmitted to the brain.
Thus, Sensory transduction is the correct answer.
