Solution

The correct option is C Nettie Stevens
Nettie Maria Stevens was an early American geneticist. She and Edmund Beecher Wilson were the first researchers to describe the chromosomal basis of sex. She identified the Y chromosome in the mealworm, Tenebrio. She deduced the chromosomal basis of sex depended on the presence or absence of the Y chromosome.
Thus, the correct answer is option C.
