Question

1. predict: place two of the ff offspring into the holding cages. click clear, and then place them into the parent boxes.

a. which allele(s) could the offspring inherit from parent 1?

b. which allele(s) could the offspring inherit from parent 2?

c. what are the possible genotypes of the offspring?

Explanation:

Part A

Parent 1 has genotype \( Ff \). When producing gametes, it can pass on either the \( F \) or \( f \) allele (due to segregation of alleles during meiosis). So the offspring could inherit \( F \) or \( f \) from parent 1.

Parent 2 also has genotype \( Ff \). Similar to parent 1, during gamete formation, it can pass on either the \( F \) or \( f \) allele (because of allele segregation in meiosis). Thus, the offspring could inherit \( F \) or \( f \) from parent 2.

To find possible genotypes, we use a Punnett square for the cross \( Ff\times Ff \). The possible combinations from parent 1 (\( F \) or \( f \)) and parent 2 (\( F \) or \( f \)) are:

• \( F \) (from 1) and \( F \) (from 2) gives \( FF \)
• \( F \) (from 1) and \( f \) (from 2) gives \( Ff \)
• \( f \) (from 1) and \( F \) (from 2) gives \( Ff \)
• \( f \) (from 1) and \( f \) (from 2) gives \( ff \)

So the possible genotypes are \( FF \), \( Ff \), and \( ff \).

Answer:

\( F \) or \( f \)
