The dominant allele H reduces the number of body bristles in fruit flies, giving rise to a hairless phenotype. In the homozygous

DerKrebs [107]

Answer:

a. 3:1 (normal bristles to hairless)

b. 2:1 (normal bristles to hairless)

Explanation:

a. If H allele is present, the fly will be hairless. But H allele is lethal at homozygous condition, so all hairless flies will be heterozygous for H locus (Hh). S allele has no effect on bristle number, but in presence of H allele, S produces a "normal" phenotype and is also lethal at the homozygous condition. So genotypes and phenotypes will be like this:

- SSHH: No viable- Lethal

- SSHh: No viable-Lethal

- SShh: No viable-Lehtal

- SsHH: No viable-Lethal

- SsHh: Normal

- Sshh: Hairless

- ssHH: Normal

- ssHh: Normal

- sshh: Normal

A cross between two normal flies carrying the two alleles (SsHh) will produce (according to the attached Punnett Square):

6 Normal (SsHh, ssHh, and sshh)

2 Hairless (Sshh)

Therefore, the ratio of flies with normal bristles to hairless individuals will be 3:1.

b. When the hairless progeny of the previous cross (Sshh) are crossed with one of the parental normal flies from part a (SsHh), it will be produced (according to the second Punnett Square):

8 Normal (SsHh, ssHh, and sshh)

4 Hairless (Sshh)

So, the ratio of flies with normal bristles to hairless individuals will be 2:1.

if the carbohydrate content of the diet is insufficient to meet the body's needs for glucose, what can be converted to glucose?

BigorU [14]

The answer is "amino acids<span>".

Carbohydrates are easy to breakdown to make energy. But, if there is a carbohydrate deficiency, then the body will start to breakdown amino acids to make energy. The main energy sources are carbohydrates, fats and proteins. In order to keep the body alive, body will breakdown nucleic acids (RNA, DNA) when there is not enough food to make energy.</span>
