Question

7. Which of the following is the most likely phenotype ratio outcome of a cross between a heterozygous tall plant and

a heterozygous tall plant?
MeTall h=short
A 63 tall: 59 short
0.76 tall : 23 short
C24 tall: 49 medium 125 short
D. 53 tall: 147 short

Answer 1

76 tall, 23 short

Step-by-step explanation:

Using T as the dominant tall gene and t as the recessive short gene, a punnett square crossing the 2 plants would yield 1 TT, 2 Tt, and 1 tt. Therefore, and estimated 3/4 of the offspring will be tall and 1/4 will be short, making the second answer the closest to this ratio.

Answer 2

B. 76 tall 23 short

Step-by-step explanation:

punnet squares! 2/4 of the offspring will have the genotype Tt (tall); 1/4 would have TT (tall), and 1/4 would have tt (short).
