Classify the mutations as somatic or inherited
Sergio [31]

Answer:

Somatic mutations : option (A) and option (D).

Inherited mutations : option (B) and option (C).

Explanation:

Mutations are permanent changes in the genetic material due to alterations in DNA sequence. Mutations may be somatic or inherited (or germline).

Somatic mutations are those mutations that arise in somatic or normal body cells and cannot transfer from parents to their offspring. As skins cells and lung cells are somatic cells, option (A) and (D) represent somatic mutations.

Inherited mutations are those mutations that arise in sex cells (gamete forming cell) and transfer from parents to their offspring due to transfer as these cells form mutated gametes. As egg cells and sperms cells are sex cells, option (B) and (C) represent inherited mutations.

Albinism in humans is caused by homozygosity for mutant recessive alleles of the tyr gene, which is located on chromosome 11. al
yanalaym [24]
Exactly 989527/1048576, or approximately 94.37%  
Since each trait is carried on a different chromosome, the two traits are independent of each other. Since both parents are heterozygous for the trait, each parent can contribute 1 of a possible 4 combinations of the alleles. So there are 16 possible offspring. I'll use "a", "A", "b", "B" to represent each allele and the possible children are aabb, aabB, aaBb, aaBB, aAbb, aAbB, aABb, aABB, Aabb, AabB, AaBb, AaBB, AAbb, AAbB, AABb, and AABB 
Of the above 16 possibilities, there are 7 that are homozygous in an undesired traint and 9 that don't exhibit the undesired trait. So let's first calculate the probability of "what are the chances that all 5 children not exhibiting an undesired trait?" and then subtract that result from 1. So 
1-(9/16)^5 = 1 - 59049/1048576 = 989527/1048576 which is approximately 0.943686485 = 94.3686485%  
So the answer is exactly 989527/1048576, or approximately 94.37%
