1021 12 2212 2021 11 21 12 21 Parent 1Parent 2Offspring 1Offspring 2 Offspring 1 becomes Parent 1 for next generation This is what your data screen looks like from the simulation with the exception of Offspring 2. Offspring 2 is the new genotype of the person with whom you mated. It is not recorded in your data screen but you can collect that data by looking at that person’s new genotype after mating.

For example, if you determined that 1 indicated heterozygous that means that 1 codes for a male since the male genotype is XY. Therefore, 2 indicates homozygous since female is XX. 1 is M 2 is F

Then, determine how to represent homozygous dominant, heterozygous and homozygous recessive.
