Answer:

Option B, 1/2 white ; 1/2 black

Genotype ratio Ww:ww

Option C, 1:1

Explanation:

Given –  

First parent is heterozygous white  with genotype Ww

Second parent is homozygous black (ww)

If these two parents are crossed each other , the following offsprings are produced –  

W w

w Ww ww

w Ww ww

The genotype of Ww is white in color

The genotype of ww is black in color  

Thus there are ½ white and ½ black  

Genotype ratio –  

Ww: ww

2: 2

1:1

lesya692 [45]

Answer:

here

Explanation:

In a negative feedback loop, an increase in a factor will result in a change in the body that'll reduce the value of this factor to the set point.

For example, an increase in the blood glucose levels after a meal will cause an increase in the levels of insulin in the blood which will lower the glucose levels.

However, in this example, an increase in the pressure generated by the fetus also increases the frequency of uterus contractions. So the more the pressure, the more the contractions.
