Solution
The correct option is A Homozygosity
Inbreeding increases the frequency of homozygosity. For example, if we started off with a set of parents such that each have one copy of the gene for increased milk production and one copy of regular milk production, using the punnett square, we can deduce that there is a 25% chance of the progeny being a purely high milk producer carrying both copies of the superior gene. Over time, we can breed individuals that have both copies of the superior gene (MM) thereby ensuring that 100% of the progeny are now superior individuals (as shown in the second Punnett square).
