Red-green color blindness is due to an X-linked recessive allele in humans. A widow�s peak (a hairline that comes to a peak in the middle of the forehead) is due to an autosomal dominant allele.Consider the following family history:
A man with a widow�s peak and normal color vision marries a color-blind woman with a straight hairline.
The man�s father had a straight hairline, as did both of the woman�s parents.
Use the family history to make predictions about the couple�s children.
Drag the correct label to the appropriate location in the table. Not all labels will be used.
What is the chance that any daughter the couple has will be color blind with a straight hairline?

Based on the exercise data we know that the couple genotype for red-green color blindness is:

(XY     x     X'X')

     X'        X'

X    X'X      X'X

Y   X'Y      X'Y

And the genotypes for widow's peak are:

  (Aa   x  aa)

Except some of the sponges, all the animals are heterotrophs as they cannot make their own food(photosynthesis).

Heterotrophs depends on autotrophs or some other organisms for their food.

They are dependent on other organisms for their energy needs.
All animals are heterotrophs.
