The genotype of individual 7 would be Mm.
Explicación
## Step 1The problem involves understanding the inheritance of traits, specifically the Marfan's trait, which is dominant. The genotype of both individuals is given as Mm. ## Step 2The genotype Mm consists of one dominant allele (M) and one recessive allele (m). The dominant allele (M) is responsible for the Marfan's trait.## Step 3When two individuals with the genotype Mm reproduce, the possible genotypes of their offspring can be determined using a Punnett square. The Punnett square is a graphical representation that shows the possible combinations of alleles that can occur in the offspring.## Step 4The Punnett square for this cross would look like this:| | M | m ||---|---|---|| M | MM | Mm || m | Mm | mm |## Step 5From the Punnett square, we can see that there is a 75% chance (MM, Mm, Mm) that the offspring will have the Marfan's trait (M) and a 25% chance (mm) that the offspring will not have the Marfan's trait.## Step 6Therefore, the genotype of individual 7, which is one of the offspring, could be either MM, Mm, or mm. However, since the Marfan's trait is dominant, the most likely genotype for individual 7 would be Mm.
