Brut [27]

Answer:

Total four genotypes and its frequency  

SsWw – 4/16

ssWw- 4/16

Ssww - 4/16

ssww - 4/16

Phenotype –  

SsWw – Heterozygous  Spotted skin and heterozygous wooled hair

ssWw  - Homozygous non-spotted skin and heterozygous wooled hair

Ssww  -  Heterozygous  Spotted skin and Homozygous non -wooled hair

ssww  - Homozygous non-spotted skin  and Homozygous non -wooled hair

Explanation:

Given -

Allele for spotted skin is "S"

Allele for non-spotted skin is "s"

Allele for Wooly hair is "W"

Allele for non-wooly hair is "w"

Allele "S" is dominant over "s"

And Allele "W" is dominant over "w"

Cross is carried out between heterozygous spotted, non-wooly man and heterozygous wooly-haired, non-spotted woman

Genotype of heterozygous spotted, non-wooly man - Ssww

Genotype of  heterozygous wooly-haired, non-spotted woman - ssWw

Ssww * ssWw

Answer:

1. The difference between the normal hemoglobin protein DNA sequence and the sickle cell hemoglobin DNA sequence is a base to base shift, in this case adenine (GAG) to thymine (GTG).

2. The difference affects the amino acid sequence of the protein by replacing glutamic acid (Glu) with valine (Val).

Explanation:

In sickle cell anemia, a change in the DNA nucleotide sequence is observed, where adenine is substituted by thymine, whose expression is the change in the amino acid sequence of globine β, incorporating valine instead of glutamic acid. This represents a molecular mutation - point mutation - by subtitution, which corresponds to missense mutation.

<u>Normal hemoglobin protein in a RBC</u>

DNA                 CTG ACT CCT GAG GAG AAG TCT

Amino acids     Leu  Thr   Pro   Glu   Glu   Lys   Ser

<u>Sickle cell hemoglobin protein in a RBC</u>

DNA                 CTG ACT CCT <em>GTG</em> GAG AAG TCT

Amino acids     Leu  Thr   Pro   <em>Val</em>   Glu   Lys   Ser

When GAG is transcribed to mRNA, the CUC codon is obtained, which codes for glutamic acid. Thymine substitution causes the DNA sequence to change to GTG, which is transcribed as CAC, the codon that encodes the amino acid valine. The <u>change from glutamic acid to valine in β-globin causes an altered hemoglobin, giving the abnormal erythrocytes observed in sickle cell disease</u>.
