An organism is a heterozygote or is heterozygous at a locus or gene when it has different alleles occupying the gene's position in each of the homologous chromosomes. In diploid organisms, the two different alleles were inherited from the organism's two parents. For example a heterozygous individual would have the allele combination Pp

what i learned from gcse double science.
het is a type of gene that can be either dominant or resessive. in organisms there is always two genes, one from the mother and one from the father. if the mother is a normal (without hets), or double dominant, the genes she will carry are XX if the father was a recessive, his genes would be xx. all of the offspring would be het, having either Xx or xX genes. if both paretns were hets, having Xx (or xX, there the same) the offspring would be 1/4 dominant XX, 1/4 recessive xx, and 1/4 recessive Xx (or xX). it can easily be worked out in this table: ![]() the mothers genes are in red, and the fathers in blue. the diagram shows the likely outcome of the babies. green is a het mauve is the dominant and yellow the ressesive. if the one of the parents had differnt genes, the table would change acoordingly. hope this helps.
