Crossing each other is relative. If phenotype A is the male parent and phenotype A is the female parent, it is called reciprocal crossing.
Because the cytoplasmic genes are all from the female parent, and the genotypes of reciprocal crosses are different, the phenotypes of reciprocal crosses are also different. Therefore, the phenotype of reciprocal crossing is different from cytoplasmic inheritance.
When the nucleus is inherited, half the genes come from parents. For homozygous parents (homozygous by default in the textbook), the genotype of reciprocal cross is the same, so the phenotype of reciprocal cross is the same. Therefore, the same phenotype of reciprocal crossing is nuclear inheritance.
What do you mean by orthogonal and reciprocal crossing in biology?
If the orthogonality is Aa as the male parent and AA as the female parent; Then backcross is Aa as the male parent and AA as the female parent. If the orthogonality is Aa as the male parent and AA as the female parent; Then backcross is Aa as the male parent and AA as the female parent. Orthogonal and reciprocal are just corresponding names.
What are orthogonal and inverse intersection?
Dominant hybridization as male parent and recessive hybridization as female parent are orthogonal. Invisible male parent, dominant female parent, that is, reverse hybridization The two are relative.
