Answer:
Homozygous genotype
Step-by-step explanation:
The inbreeding is a kind of mating which involves relatives. The relative parents produce progeny with homozygous genotype. This process of inbreeding decreases the heterozygosity.
For example, relative parents with genotype Ee and eE were crossed. This resulted in Ee, EE, ee and eE progeny. The mating of progeny ee and Ee will result in a offspring of ee genotype. This causes homozygosity. This occurs because both the parents share common ancestors.
