In an experiment. Red flowered 4 O'clock plant is crossed with a While flower. 4 O'clock plant. The F1 generation plant is crossed and prcduced the F2 generation. The phenotypic and genotypic ratio is 1:2:1. Name the type of inheritance? Explain.

In guinea pigs the gene for rough coat (R) is dominant over that for smooth coat (r) and the gene for black hair (B) is dominant over that for white hair (b). If a homozygous rough black animal is crossed with a homozygous smooth white one. What will be the genotype and phenotype in the F_1 generation?

In the given pedigree the shaded figures denote individuals expressing a specific trait. which of the following is the most probable mode of Inheritance of this trait. A - simple Mendelian Recessive B- Co dominant relationship of a single pair on alleles C-X - linked recessive transmission D-X-linked dominant transmission E-Polygenic inheritance
