Sickle-cell trait is caused by a single defective allele, but sickle-cell disease only occurs in individuals that are homozygous
Pavel [41]

Answer:

6,25%

Explanation:

Considering that the couple has a trait of sickle cell anemia, we know that both are heterozygous for the disease (Aa) and therefore can have children with the following genotypes:

Parents: Aa X Aa

Children: AA(A x A), Aa(A x a), Aa (a x A) and aa(a x a)

Knowing that sickle cell anemia only occurs in homozygous individuals, the probability for children to have the disease according to each crossing is:

A x A = 1/4 = 25%

A x a = 1/4 = 25%

a x A = 1/4 = 25%

a x a = 1/4 = 25%

The probability of forming each homozygous child (aa) is 1/4 or 25%. Since they are two children, the probability of both having sickle cell anemia is calculated by multiplying the probability of each, so:

1/4 × 1/4 = 1/16 = 0.0625 = 6.25%

It is concluded that the probability of a heterozygous couple for sickle cell anemia to have two children with the disease is 6.25%.

<h2>Answer is "RuBisco"</h2>

Explanation:

  • It contains high measures of fundamental amino acids, which makes it somewhat interesting among vegetable proteins. Because of its properties, RuBisCo is a generally excellent possibility for food applications. It can not exclusively be utilized as a protein source yet in addition as an emulsifier, frothing and gelling operator
  • RuBisCO, and it is a type of protein, called an enzyme, that is involved in the Calvin cycle.An enzyme is a type of protein that makes reactions occur faster. For example, there is an enzyme in our body that helps transfer carbon dioxide from our cells to our blood. This reaction occurs 107 times faster with the enzyme
  • Hence, the right answer for fill up the blanks is "RuBisco"
