Imagine that height in corn plants is determined by three loci. The baseline height is 100 cm. Every + allele adds 10cm to the plant’s potential height, every – allele subtracts 10 cm from the plant’s potential height. The shortest possible plant and the tallest possible plant are mated to form an F1, what is the height of the F1?

Two varieties of maize averaging 50 and 20 inches in height, respectively, are crossed. The F1 progeny is quite uniform averaging 35 inches in height. Out Of the 16 F2 plants, the 5 are 35 inches. What is the probable number of independent segregating polygenes involved in this trait?

In a plant, height is control by three quantitative trait loci. Each dominant additive allele is contributing 3 cm height in plant. Maximum expected plant height is 20 cm. What is minimum expected height?

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 ?

#Unit 8. Inheritance Biology
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?
