Answer:

<u>D) the nucleic acid (either DNA or RNA)</u>

<u />

Explanation:

Phages, or bacteriophages are viruses that infect bacteria.They have varying shapes, and sizes, and may contain one of two kinds of nucleic acid; these are RNA and DNA.

The nucleic acids  are made up of nucleotides. These are  genetic storage biomolecules made up of the monomers ribonucleic acid (RNA) deoxyribonucleic acid (DNA).

Answer:

75% brown, 25% white

Explanation:

This question involves a single gene coding for color in chickens. The allele for brown color (B) is dominant over the allele for white color (b).

According to this question, a brown rooter with genotype 'BB' was crossed with a white hen (bb). The offsprings in the F1 generation will all possess the 'Bb' genotype and be brown colored. However, if these F1 offsprings are self-mated i.e Bb × Bb, the proportion of F2 offsprings will be 1BB, 2Bb, 1bb.

Since BB, Bb and Bb offsprings are Brown in color and bb is white in color, this means that the expected phenotypic appearance of the F2 offsprings will be:

¾ or 75% brown and ¼ or 25% white

Assuming that the affection is a recessive trait caused by a single diallelic gene, the percentage of the population that possess the heter0zyg0us advantage is 32%.

<h3>Available data</h3>

  • 1000 of African people population
  • 4% of the population is born with sickle cell anemia

100% of the population -------------------- 1000 individuals

4% of the population with anemia------- X = (4 x 1000) / 100 = 40

0.04 is the frequency of individuals with sickle cell anemia.

Assuming that the affection is a recessive trait caused by a single diallelic gene, we can get the allelic frequency as follows.

  • The genotypic frequency is q² =  0.04
  • The allelic frequency is q = √0.04 = 0.2

Having the recessive allelic frequency, we can get the dominant allelic frequency, by clearing the following equation,

p + q = 1

p = 1 - q

p = 1 - 0.2

p = 0.8

So, the allelic frequencies are

p = 0.8

q = 0.2

To get the heter0zyg0us frequency, we just need to replace the values

2pq = 2 x p x q = 2 x 0.2 x 0.8 = 0.32

The frequency of the heter0zyg0us genotype is 0.32 = 32%.

32% of the population possess the heterozygous advantage.
