In a small population of Brazilian natives, the frequency of gene p, responsible for this disease, is 0.3. What must be the frequency of people who are heterozygous for this disease?

Answers

Answer:

Explanation:

According to hardy weinberg

p+q=1

p2+2pq+q2=1

p stands for the dominant genotype

q stands for recessive genotype

pq stands for population that are not homogenous i.e not the same

Given that p=0.3

P2=0.09

q=1-0.3= 0.7

q2=0.49

2pq= 2×0.3×0.7

=0.42

Therefore, the frequency of heterozygous population is 0.42

p2+2pq+q2

0.09+0.42+0.49 = 1

Is the widely accepted scientific theory that characteristics of a population may change over time, and that current species may gradually give rise to new species.

Answers

Answer:

Evolution theory

Explanation:

The evolution theory was developed by Darwin and it is a generally accepted theory that deals with gradual changes in the characteristics of organisms due to their quests to adapt to continuous changes in the environment.

As the environment of organisms keeps changing, the population of the organism keeps adjusting. Individuals that are able to adjust to the changes survive and are able to reproduce while the weak ones gradually die off from the population.

Hence, the entire characteristics of the population is changed with time as a result. The continuous changes sometimes lead to some species within the population giving rise to a new species entirely.
