Question

if these five plants reproduce, mating randomly, what will be the frequency of solid, pink-flowered plants in the offspring? (round your answer to the nearest 100th place.) [ select ]

Answer 1

Rounding to the nearest 100th place, the answer is 25.00%.

Assuming complete dominance of solid color over pink and a heterozygous F1 generation with all pink flowers (Ss), the Punnett square for the next generation (F2) reveals:

1/4 SS (solid)

2/4 Ss (pink)

1/4 ss (solid but non-viable due to lethal allele combination)

Therefore, the frequency of solid, pink-flowered plants (SS + Ss) in the offspring is:

(1/4 + 2/4) * 100% = 75%

However, due to the lethal ss genotype, only 3/4 of the offspring survive. So, the frequency of surviving solid and pink-flowered plants (SS + Ss) becomes:

(75% * 3/4) * 100% = 56.25%

Rounding to the nearest 100th place, the answer is 25.00%.
