In chickens, having feathers on legs is dominant to having featherless legs. In a population of 200 chickens, 128 have featherle
Neporo4naja [7]

Answer:

64

Explanation:

Since the population is in Hardy-Weinberg equilibrium and the equilibrium is defined by the equation

p² + 2pq + q²

where the frequency of the homozygous dominant allele F ( feathers on the leg ) = p²,

F of homozygous ( featherless legs) = q²

F of heterogyous ( carrier of featherless allele) = 2pq

F (q²) = 128/200 = 0.64

q = √0.64 = 0.8

and p + q = 1

p = 1 - 0.8 = 0.2

2pq = 2 × 0.2 × 0.8 = 0.32

number of chickens that are heterozgous for the feathered leg allele = 0.32 × 200 = 64

Describe how DNA replication relates to transmission and conservation of genetic information.
Jet001 [13]
DNA replication follows the base pairing rule (A with T and G with C). This ensures identical replication of the genetic information; hence it's conservation. Each daughter DNA double helix contains one old strand of DNA and one newly-synthesized strand of DNA. This is known as the semi-conservative mechanism.
DNA replication also occurs during mitosis which produces haploid gametes. Each parent contributes half of the genetic information during fertilization of two gametes, thus regenerating the diploid number. Genes from both parents are transmitted to the offspring.
