The frequency of homozygous dominant individuals in this population is 0.55.
<u>Explanation</u>:
According to Hardy-Weinberg Equilibrium,
p + q = 1
For the Homozygous recessive gene is given by ².
where, p represents the frequency of dominant gene.
q represents the frequency of recessive gene.
² = 20 % = 20 / 100 = 0.2
q =
q = 0.45
p + q = 1
p = 1 - q
= 1 - 0.45
p = 0.55.
The number of children born to an average woman in a population during her entire reproductive life is called total fertility rate (TFR).
The total fertility rate (TFR) is the total number of children likely to be born to a woman in the population if she were subject to the childbearing years giving birth to children according to an existing schedule of age-specific fertility rate. The total fertility rate is obtained by adding the single-year age-specific rates at a specific time.
The answer is c. Adaptation
Adaptation is a physical characteristic that helps an organism survive in an environment. This help them survive in a natural selections.
The examples are :
- cactus that evolved to change its body structure to retain as much water as possible
- Bat that have adapted their hearing to hunt at night
Answer:
the amino a acid sequence would be identical to human cell
becuuse the codes sequencing is simialr in all animals
