The genotype of the mother must be heterozygous.
<h3>Punnet' square</h3>
In order to obtain a probability of 25% red-eyed males from the offspring, the mother must be heterozygous for the trait. The father can be of any genotype.
Thus, the likely genotype combination that will result in 25% red-eyed males are:
x 
- and
When you cross the first one above, the genotype of the offspring would be 
.
The second cross will give offspring with the genotypes 
Both crosses give a 25% chance of producing re-eye males.

Predetors have to eat. If things are good which means the predetors can eat good also.Starvation means that things in the eco-system are going bad.Also,it helps the earth,maintain its balance.If too much of any aspect of the system is removed it throws the whole thing off balance. Too many herbivores will eat too much vegetation.</span>
Answer:
Because T-cell-independent antigens do not activate helper T cells, they fail to induce B cell memory, affinity maturation, or class switching, all of which require help from T cells. They therefore mainly stimulate the production of low-affinity (but high-avidity) IgM antibodies.
Explanation:
