Explanation:

50%; homozygous recessive; phenotype

According to the Punnett square, offspring from these two parents have a 50%chance of inheriting two b alleles. Individuals that inherit two b alleles are homozygous recessive . Inheriting two b alleles confers the phenotype of blue eyes.

Inheritance describes the way in which certain traits are passed onto offspring of sexual reproduction. For instance, co-dominance, both of a gene's alleles are present, and notable in the phenotype.

The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, in the cell. Sequences of DNA make up genes which can have different forms called alleles and comprise the genotype. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins. These proteins, when expressed, are referred to as an organism's phenotype.

Compare each patient's cdna sequence to the wild-type cdna sequence. Each patient has one nucleotide-pair substitution mutation.

Lera25 [3.4K]

The mutation is a change in the nucleotidic sequence. In the exposed example, Patient 1: nucleotide 143, TTC⇒TGC. Patient 2: nucleotide 143, TTC⇒TCC. Patient 3: nucleotide 147, TTC ⇒ TTG.

<h3>What is a mutation?</h3>

A mutation is a change or alteration in DNI sequences that introduce new variants.

Many of these are eliminated, but some of them might succeed and be incorporated into each individual.

These mutations are the ones that have been selected by natural selection.

<h3>Solving the problem</h3>

We know that each sequence initiates with nucleotide number 103 and ends in nucleotide 162.

So first, we will number the nucleotides, from 103 to 162. Each nucleotide has a number in increasing order.

Now, we will identify the mutations in each of the strands by comparing them with the wild-type sequence. The mutation occurs in one of the nucleotides, so we must look for the change in the bases.

Finally, we will identify the nucleotide location of each mutation.

nucleotide wild-type mutated

location nucleotide nucleotide

Patient 1 143 TTC TGC

Patient 2 143 TTC TCC

Patient 3 147 TTC TTG
