What Is Test Cross, Back Cross, Reciprocal Cross, Outcross With Clear Definition And In Checkerboard Give Some Examples For That
Answers
Back-cross-The F1 individuals obtained in a cross are usually selfed to get F2progeny. They can also be crossed with one of the two parents (P1or P2) from which they are derived. Such a cross of F1hybrid individual with either of the two parents is called backcross.
11)Test-cross-In this cross, the individual of an unknown genotype is crossed with homozygous recessive parents.
12)Out-cross-In this cross, the individual of an unknown genotype is crossed with homozygous dominant parents.
13)Reciprocal cross-A set of two reciprocal crosses means that the same parents are used in two experiments in such a way that if one experiment 'A' is used as the female parent and 'B' is used as the male parent, in the other experiment, 'A' will be used as the male parent and 'B' as the female parent. The purpose of this is to find out whether both parents are making an equal contribution.
