Q 12.9. The following pedigree includes individuals that carry a recessive mutation that leads to embryo lethality. Heterozygous individuals are marked with a single dot. Those that carry the mutation at the homozygous state are indicated with two dots. Dots are represented in colors that allow identification of the source of each mutant allele within the pedigree. Please, identify those individuals that are likely to die at the embryo stage if this gene is maternally imprinted. If some individuals are not supposed to exist in the pedigree because one/both of their parents died at the embryo stage, please identify them as well. Please explain your answers.
