Question

select all the correct answers.
which two statements are true for the cross illustrated by this punnett square?
punnett square with columns r, r and rows r, r; cells: rr, rr, rr, rr
r-smooth seeds, r-wrinkled seeds
□ the f1 generation will be homozygous.
□ the entire f1 generation will be hybrid.

Explanation:

1. Analyze the Punnett square: The cross is between a parent with homozygous dominant alleles ($RR$, smooth seeds) and a parent with homozygous recessive alleles ($rr$, wrinkled seeds). All offspring are $Rr$.
2. Evaluate first statement: Homozygous means having two identical alleles. The offspring are $Rr$ (two different alleles), so this statement is false.
3. Evaluate second statement: Hybrid (heterozygous) means having two different alleles. All offspring are $Rr$, so this statement is true.

Answer:

The entire F1 generation will be hybrid.
