A woman with normal BRCA alleles has a child with a man who has one mutated BRCA1 allele. What is the probability that the child
grigory [225]

Answer:

50%

Explanation:

According to the given information, the woman has normal BRCA alleles while the man carries one copy of the mutated BRCA allele (BRCA1). A diploid organism such as human beings can have two BRCA alleles. A child gets one BRCA allele from the mother and the other from the father.

The child of the couple would get one normal allele from the woman. However, with respect to the BRCA allele, the man would form two types of gametes in equal proportion. The 50% of his gametes would have the mutated BRCA1 allele while the rest 50% would carry the normal BRCA allele. Therefore, the man can transmit either normal or mutated BRCA allele to the child. So, there are 50% chances for the child to get the mutated allele.

kvv77 [185]

The stage is the last stage of speciation The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.

Speciation is split into 3 stages:

a) Separation.

b) Adaptation.

c) Reproductive Isolation.

Stage 1 Separation

  • A part of the populace separates and adapts to a brand new environment. Natural occasions along with tsunamis, tidal waves can reason organisms to split from their preliminary habitat to a brand new environment.

Stage 2: Adaptation.

  • At this stage, the organisms evolve new trends that permit them to a brand new environment. They own sure traits that permit them to match into the brand new environment. Example The notable white skin's color makes it tough for it to be visible withinside the dark.

Stage 3: Reproductive Isolation.

  • At this stage, organisms of the equal species reunite and do now no longer interbreed. e, species are remoted into new ones in order that they have the great diversifications for or her new habitat.

<h3>What is speciation?</h3>

Speciation is an evolutionary method where the new species arises from previous ones.

Hence concluded that speciation involves the stage where the populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.
