Question

type the correct answer in the box.
a snapdragon with pink flowers with the genotype rr is mated with a snapdragon with red flowers with the genotype rr. what is the possibility of obtaining a flower with a heterozygous genotype?
the possibility of obtaining a heterozygous flower is
%

Explanation:

Step1: Determine the gametes

The pink - flowered snapdragon (Rr) can produce gametes R and r. The red - flowered snapdragon (RR) can produce gametes R only.

Step2: Create a Punnett square

	R	R
r	Rr	Rr

Step3: Calculate the probability

There are 4 possible genotypes in the Punnett square. The heterozygous genotype (Rr) appears 2 times. The probability is calculated as $\frac{2}{4}=\frac{1}{2}=50\%$

Answer:

50
