which punnett square represents a cross between two parents that are heterozygous for purple flowers?
which punnett square represents a cross between two parents that are heterozygous for purple flowers?
Answer
Explanation:
Step1: Define heterozygous genotype
Heterozygous means having two different alleles. If the allele for purple - flower is F and the non - purple allele is f, heterozygous parents have the genotype Ff.
Step2: Set up Punnett square
When two parents with genotype Ff are crossed, the possible gametes from each parent are F and f. The Punnett square has rows and columns labeled with the possible gametes of each parent.
Step3: Fill in Punnett square
When we fill in the Punnett square, we combine the gametes. The top - left box is from the combination of F from one parent and F from the other (FF), the top - right box is from F and f (Ff), the bottom - left box is from f and F (Ff), and the bottom - right box is from f and f (ff).
Answer:
The first Punnett square (with FF, Ff, Ff, ff) represents a cross between two parents that are heterozygous for purple flowers.
