Question: After cross-breeding true-breeding tall and dwarf pea plants, the resulting F1 generation was allowed to self-pollinate. What is the genotype ratio of the resultant plants?#

A) 1:2:1 (homozygous tall : heterozygous tall : dwarf)

B) 1:2:1 (heterozygous tall : homozygous tall : dwarf)

C) 3:1 (tall : dwarf)

D) 3:1 (dwarf : tall)

Answer: 1:2:1 (heterozygous tall : homozygous tall : dwarf)#
