Answer:

a. Male

Step-by-step explanation:

The male chromosome is the sex determiner for many species, because the female chromosome is usually doubled (homozygous). For example, us humans it is XX. However, the male chromosome is usually different (heterozygous). For example, us humans it is XY. Therefore, the mother will always pass, in our case a X chromosome. However, the father can pass either the male determining gene (Y) or the female determining gene (X).
