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.

Answer:
The type of immunization used is passive, and the exact agent used is an antivenom. This type of immunization is necessary because the man does not have antibodies to fight against the venom's toxins.
Explanation:
To treat from snake bites is necessary to use antivenoms, these are given to the patient as soon as possible after the bite, they consist on a mixture of hyperimmune globulins and other proteins obtained from the serum of animals, usually horses or sheep, previously immunized with the venom of a snake. This kind of immunization is called passive immunization, is temporary and it uses exogenous preformed antibodies to provide treatment to an unprotected individual.
In this case, we use this kind of immunization because the person who was bitten didn't have the previous contact with the snake's venom, this means that the victim does not have antibodies to fight against the toxins in their body.
