Answer: The correct answer is -

B) a sugar found in DNA.

Explanation:

DNA (deoxyribonucleic acid) is the genetic material of living organisms that is passed from one generation to the next generation.

It is composed of small units called nucleotides, which contain three components -

deoxyribose sugar ( 5 carbon or pentose sugar that lacks - OH at 2'position in the pentose structure and contains hydrogen in its place), a nitrogenous base (which can be adenine, cytosine, thymine or guanine) and a phosphate group.

Thus,option B) is the right answer.

Phenylketonuria, PKU, is a single-gene recessive human
astraxan [27]

Answer:

1/2

Explanation:

Let's assume that the allele "p" is responsible for PKU in the homozygous state. According to the given information, both the parents are unaffected by the disorder but have an affected child. This means that both the parents carry at least one copy of the recessive allele responsible for the disease. Therefore, the genotype of each of the parents is Pp. A cross between Pp and Pp would produce progeny in following ratio=

Pp x Pp = 1/4 PP: 1/2/ Pp: 1/4 pp

Therefore, the probability that their next child will carry just one recessive allele is 1/2.
