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 %.
Answer
Explanation:
Step1: Set up Punnett - square
The genotypes of the parents are Rr and RR. The possible gametes from Rr are R and r, and the possible gametes from RR are all R.
Step2: Fill in Punnett - square
| R | R | |
|---|---|---|
| R | RR | RR |
| r | Rr | Rr |
Step3: Calculate probability
There are 4 possible genotypes in the offspring. 2 of them are Rr (heterozygous). The probability is $\frac{2}{4}=0.5$ or 50%.
Answer:
50
