Question
T = tall and t = shortA homozygous dominant tall pea plant is crossed with a heterozygous pea plant. This cross would result in the following phenotype(s) of the offspring: Group of answer choices100% tall100% short75% tall and 25% short50% tall and 50% short
Solution
The answer is 100% tall.
Here's the step by step explanation:
-
A homozygous dominant tall pea plant has the genotype TT. This means both alleles for height are the dominant (Tall) allele.
-
A heterozygous pea plant has the genotype Tt. This means one allele is dominant (Tall) and the other is recessive (short).
-
When these two plants are crossed, the possible combinations of alleles in the offspring are TT and Tt.
-
Both of these genotypes result in tall plants because the presence of at least one dominant (Tall) allele results in a tall plant.
-
Therefore, 100% of the offspring will be tall.
