12. A baby crawfish has a long tail. Its mother has a long tail while its father has a short tail. Which of these statements explains why the baby has a long tail?

Due to the presence of dominant allele.

Explanation:

The long tail feature comes to the offspring from their mother due to the presence of dominant allele. The dominant allele appears in the shape and structure of the offspring as compared to recessive allele which hide in the structure. The long tail appears in the structure of the baby crawfish so we can say that it is a dominant allele that transfer from the female parent into the offspring. In the offspring, some traits are transferred from father and some from mother.
