In a population of pea plants, 36 plants are homozygous for the dominant trait of yellow peas (YY), 48 plants are heterozygous f
baherus [9]

Answer:

The correct answer would be C. 0.60

It can be calculated with the help of Hardy-Weinberg equation i.e

p² + q² + 2pq = 1

Also, p + q = 1

  • where p represents the frequency of dominant allele.
  • q represents the frequency of recessive allele.
  • p² represents the frequency of homozygous dominant genotype .
  • q² represents the frequency of homozygous recessive genotype .
  • 2pq represents the frequency of heterozygous genotype.

Number of homozygous dominant (YY) = 36

Number of homozygous recessive (yy) = 16

Number of heterozygous dominant (Yy) = 48

Total number of plants = 100

Now, frequency of homozygous dominant (YY) = 36/100 = 0.36

Therefore, p² = 0.36

So, p = √0.36 = 0.60

Hence, frequency of dominant allele (Y) = 0.60

Base your answer(s) to the following question(s) on the diagram below and on
Kryger [21]

Answer:

The correct option is <em>Both Cell A&D.</em>

Explanation:

The diagram in the picture shows how a cell (A) undergoes the process of replication and produces a cell (B) containing one full set of double chromosomes.

Then, the cell undergoes the process of mitosis to produce two daughter cells (C & D).

Mitosis can be described as a method of asexual reproduction in which the daughter cells produced are identical to the parent cells and are also identical to each other. Hence, the genetic content of the cell C will be the same as the genetic content of cells A & D.
