Here, given-

homozygous alleles 'a' have a frequency of 0.3.

Also the alleles are in equilibrium in a Hardy-Weinberg population. The frequency of individuals that are homozygous for this allele are= 0.49.

The Hardy-Weinberg equilibrium can be defined as the principle which states that the variation in the genetic makeup of a population remains constant and unchanged till there are no external interferences, influencing the population.

Calculation-

p + q = 1\\0.3 + q= 1\\q= 1- 0.3\\\\q= 0.7

Then to find the frequency of the individuals homozygous for this allele the following formula needs to be used-

p^{2} + 2pq + q^{2} =1

p^{2} = dominant homozygous frequency\\2pq= heterozygous frequency\\q^{2} = recessive homozygous frequency\\

Thus, the individuals homozygous for the allele can be calculated by q^{2} = (0.7)^{2} \\= 0.49

lara [203]

Answer: The science of naming and classifying organisms based on structural comparisons and genetic evidence, is known as taxonomy, a branch of biology.

Explanation: Taxonomy is very important. By categorizing organisms, this branch of biology helps scientists to exchange vital biological information, and therefore understand the diversity of species in our planet.

LenKa [72]

Answer:

You have to use chargaff's rule:

A+G=T+C

A=T

C=G=32%

A+T=100-2x32=36%

A=18%

A=18% T=18%
