Question

use the punnett square below to identify the phenotypes of the offspring. red petals are dominant over white petals. a rr, rr, rr b 75 % red and 25 % white c 25% red, 50 % red and white, 25 % white d 25 % red, 50 % pink, 25 % white

Explanation:

Step1: Analyze genotypes in Punnett - Square

There are 4 genotypes: RR, Rr, Rr, rr.

Step2: Determine phenotype based on dominance

RR and Rr show red (dominant). rr shows white (recessive).

Step3: Calculate phenotype ratios

3 out of 4 (75%) are red (RR, Rr, Rr), 1 out of 4 (25%) are white (rr).

Answer:

B. 75 % Red and 25 % white
