Answer:

The correct answer would be option C.

Explanation:

Restriction Fragment Length Polymorphism or RFLP is a method of genetic investigation on the molecular level that permits individuals to be recognized based on distinctive patterns of restriction enzyme cleave in specific points of DNA.

The basic technique for the identification of RFLPs involves segmenting a sample of DNA with the help of a restriction enzyme. Restriction enzymes can selectively restrict a DNA molecule wherever specific, short sequence is recognized.

Hence, RFLPs are referred to as DNA fingerprinting bands.

Do you think that organisms of the same order will share a stronger evolutionary relationship than organisms that share only the
ahrayia [7]

Answer:

<h3>In taxonomic, the organism is classified based on some similarities. ... But the organism with the same order should have the same phylum and class too since order is located below the phylum. That means the organism with the same order should have more similarities than the organism with the same phylum.</h3>

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is inherited as an X-linked recessive allele in humans. A woman whose father
prohojiy [21]

Answer:

(a) 1/2; (b) no

Explanation:

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is an X-linked recessive disorder and the woman's father was diseased so it means that woman is a carrier of the allele but has normal phenotype. It means that she will have XXᵇ genotype.

In contrast to this, her husband is diseased so his genotype will be XᵇY.

The Punnett square diagram related to the cross is attached.

(a) Proportion of their sons expected to be G6PD is 1/2:

They both may give birth to 4 progeny with genotypes XXᵇ, XᵇXᵇ, XY and XᵇY. It means they both may have 2 sons out of which one with genotype XᵇY will be diseased while the one with genotype XY will be healthy. So the proportion of their sons having G6PD is 1/2 or 50%.

(b) If the husband were G6PD deficient, the answer will not change.

The reason behind this is that this disease is caused by an allele located in X chromosome. But father contributes only Y chromosome to his son not X chromosome. The X chromosome will affect the genotype of his daughter not son that is why answer will not change. It means they will still have 1/2 of their sons diseased.
