Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Radish color is completely dominant, red and white are pure breeding colors. While heterozygous are purple.Cros a red radish with a white.
A
4 purple
B
1 red, 2 purple, 1 white
C
2 red, 2 white
D
1 red, 1 purple, 2 white
Explanation: 

Detailed explanation-1: -Radish color is completely dominant, red and white are pure breeding colors. While heterozygous are purple. Cros a red radish with a purple.

Detailed explanation-2: -So the correct answer to our question about the expected phenotypic ratio of a dihybrid cross between two heterozygous individuals is (A) nine to three to three to one.

Detailed explanation-3: -The shapes and colors of radishes are controlled by two independent pairs of genes that show no dominance. The color may be red (RR), white (WW), or purple (RW). The shape may be long (LL), round (OO), or oval (LO).

Detailed explanation-4: -In snapdragons, flower color is controlled by incomplete dominance. The two alleles are Red (R) and White (W). The heterozygous genotype is expressed as pink.
