Answer:

100% white cow

Explanation:

This question involves a single gene coding for skin color in cattle. The allele for red color (R) is codominant with the allele for white color (r). Hence, the roan cattle (Rr) will possess both red and white coloration.

According to this question, a white bull (rr) is crossed with a white cow (rr). Each parent will produce the "r" gamete, which when used in a punnet square will produce all WHITE COWS i.e 100% white cows. See punnet square attached.

2. Yeast metabolism produces compounds derived from tryptophan, which are found in fermented beverages, such as wine and beer. In particular, melatonin and serotonin, may be relevant due to their bioactivity in humans.

3. Serotonin is in the brain. It is thought to regulate mood, happiness, and anxiety. Low levels of serotonin are linked to depression, while increased levels of the hormone may decrease arousal.
