In a Hardy-Weinberg population with two alleles that show complete dominance, the frequency of the recessive allele is 0.4. What
Flura [38]

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%

During the cell cycle, the cell spends the most time in __________and the least amount of time in_________. * Prophae, Interphas
Law Incorporation [45]

Answer:

The cell spend most times in the interphase

The cell spend short time in the anaphase.

Explanation:

Interphase is the longest phase in cell cycle because it is a phase where series of cell of divisions take place

because there is need for the cell to grow, replicate or duplicate it's DNA and also make preparations for cell division.

Anaphase is the shortest phase because during anaphase, the sister chromatids become pulled apart to other opposite ends of the cell.
