Which type of selection on a polygenic trait increases variation in the trait

1 answer:

8 0

The answer is Mutations. It is the type of selection on a polygenic trait that increases variation in the trait. Mutations increase genetic variation, which is needed for natural selection to bring about evolutionary change. When a cell divides, it makes a copy of its DNA — and sometimes the copy is not quite perfect. That small difference from the original DNA sequence is a mutation.

Answer:

a. Two of these are correct.

Explanation:

The two correct options are

b. Is a critical component or requirement for wound healing to take place

d. Existing blood vessels give rise or sprout to form new blood vessels

Angiogenesis is the physiological means in which new blood vessels form pre-existing vessels, developed in the starting phases of vasculogenesis. Angiogenesis is a usual and important process in growth and development, wound healing and in the development of granulation tissue.

The growth and maturation of blood vessels is a largely regulated multistep mechanism called angiogenesis.

Use the Punnett square to predict the genotype for the parent organism whose genotype is unknown and

Katyanochek1 [597]

Answer: The genotype for the parent organism whose genotype is unknown is Ff.

Explanation: Let (F) represent the allele for purple which is dominant over (f) and (f) represent the allele for white.

The parent organism whose genotype is unknown is heterozygous for purple colour (Ff).

A cross between Ff and ff will produce four offsprings: two of which are Ff (heterozygous for purple colour) and two are ff (white).

Ff x ff = Ff, Ff, ff and ff.

Since (F) is dominant over (f), (Ff) will manifest as purple while (ff) will manifest as white. Therefore, half of the offsprings are purple while the other half are white.

What happens to lac when E. coli is present

Kobotan [32]

It binds lactose which changes its conformation so that is no longer binds to DNA. This allows the lactose operon to be transcribed.
