A grow seeded purple flowered heterozygous plant (YyPp) is crossed with a green seeded, white flower plant (yypp). What is the probability that an offspring of this cross produces plants with green seeds and white flower phenotypes?

Question:

A yellow seeded, purple-flowered heterozygous plant (YyPp) is crossed with a green seeded, white-flowered plant (yypp).

(Y = yellow seed allele; y = green seed allele; P = purple flower allele; p = white flower allele)

What is the probability that an offspring of this cross produces plants with green seeds and white flowers? Assume the traits assort independently.

The probability that an offspring of this cross produces plants with green seeds and white flower is 25% = 0.25

Explanation:

Available data:

Cross: A yellow seeded, purple-flowered heterozygous plant with a green seeded, white-flowered plant

Parentals)         YyPp         x     yypp

Gametes) YP, Yp, yP, yp       yp, yp, yp, yp

Punnett square)

                           YP         Yp         yP         yp

              yp      YyPp     Yypp     yyPp    yypp

              yp      YyPp     Yypp     yyPp    yypp

              yp      YyPp     Yypp     yyPp    yypp

              yp      YyPp     Yypp     yyPp    yypp

F1) 4/16 = 1/4 = 25% YyPp, Yellow seeds and Purple flowers

    4/16 = 1/4 = 25% Yypp, Yellow seeds and white flowers

    4/16 = 14 = 25% yyPp, green seeds and purple flowers

    4/16 = 1/4 = 25% yypp, green seeds and white flowers.

The probability that an offspring of this cross produces plants with green seeds and white flower is 25% = 0.25
