Question

Explain brief two factor and three factor crosses​

Answer 1

TWO FACTOR CROSS

is also called as D-i-h-y-b-r-i-d cross

D-i-h-y-b-r-i-d  cross is a cross between two different lines/genes that differ in two observed traits. According to Mendel's statement, between the alleles of both these loci there is a relationship of completely dominant - recessive traits.

THREE FACTOR CROSS

a three-point cross is used to determine the loci of three genes in an organism's genome. An individual h-e-t-e-r-o-z-y-g-o-u-s for three mutations is crossed with a  h-o-m-o-z-y-o-u-s recessive individual, and the

p-h-e-n-o-t-y-p-e-s of the progeny are scored.
