If trait are governed by polygenic. If plant genotype AABB ( 8 cm height ) were cross with aabb ( 2 cm height ) produced F1 and allowed to selfing . which of the following phenotypic height are not observe in F2 plant if all gamete participate in fertilization ?

Assume that three loci, each with two alleles (A and a, B and b, C and c), determine the differences in height between two homozygous strains of a plant. These genes are additive and equal in their effects on plant height. One strain (aabbcc) is 10 cm in height. The other strain (AABBCC) is 22 cm in height. The two strains are crossed, and the resulting F1 are interbred to produce 1000 F2 progeny. what is number of F2 progeny having intermediate height?

A plant height in Maize is control by 3 pair of polygene .Two varieties of maize averaging 120 and 60 inches in height, respectively, are crossed. The F1 progeny is quite uniform averaging 40 inches in height. What is proportional of F2 progeny that is display phenotype either 120 cm or 60 cm height?

Plant having height 6 cm are allowed to cross with plant having height 2 cm , all F1 progeny having height uniform 4 cm were allowed selfing to produced F2 progeny in which 3 plant out of 8 having height 4 cm . what are number of polygene involve in that trait ?
