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.

Marsha and Meghan drive to St. Louis to attend a Cardinals baseball game. Once inside the stadium, they decide to start drinking

zlopas [31]

Answer:

a.The alcohol is inhibiting the vasopressin hormone, also known as antidiuretic hormone (ADH).

b.The vasopressin hormone makes us retain water in our kidneys to maintain adequate water levels in our body and expel the right amount of water and other products in the urine.

Explanation:

When we drink alcohol, we inhibit the antidiuretic hormone(ADH), also called vasopressin hormone. It is responsible for the retention of water in our kidneys to absorb the products that are there. Also, it keeps the body with the right levels of liquid. If we drink alcohol, we inhibit the ADH, so we would not retain water, and as a result, we will produce more urine, which leads us to urinate more often. The consequence of this excessive loss of water is dehydration.

How does heat flow within earth change the earths surface

miss Akunina [59]

Answer:

How does all this relate to the motion of the plates on Earth's surface? The movement of heat by convection in the asthenosphere causes the rock of the mantle to slowly move in huge streams. The solid (but brittle) rock of the lithosphere is resting directly on top of the solid (but soft) rock of the asthenosphere.
