In a trihybrid cross between a tall yellow round (TTYYRR) and a short green wrinkled (ttyyrr) plant, what fraction of the F2 generation is expected to be tall, green, and round? (Tall, yellow, and round are dominant traits.) 1/4 9/64 3/64 5/12

Given the pea plant cross: ( Tt Rr yy Aa x Tt rr YY Aa ), what is the expected frequency in the progeny for the phenotype ( tall, round, yellow, terminal ) where the following alleles map to these phenotypes: T = tall, t = dwarf; R = round, r = wrinkled; Y = yellow, y = green; A = axial, a = terminal. T, R, Y, and A are dominant alleles. A) 1/32 B) 2/32 C) 3/32 D) 4/32 E) 5/32
