Question

in pea plants, the trait of producing round peas (r) is dominant to producing wrinkled peas (r). cross a heterozygous round pea plant with a wrinkled pea plant. what is the genotype ratio of the offspring?○ 2 round: 2 wrinkled○ 2 rr: 2 rr○ 4 round○ 2 rr: 2 rr

Explanation:

Step1: Identify parent genotypes

Heterozygous round: $Rr$; wrinkled: $rr$

Step2: Set up Punnett square

	$R$	$r$
$r$	$Rr$	$rr$

Step3: Count offspring genotypes

2 $Rr$, 2 $rr$

Step4: Simplify the ratio

$2 Rr: 2 rr$ (or 1:1)

Answer:

2 Rr: 2 rr
