Multiple Choice 1 point If individuals 162 both have the genotype Mm, what genotype would Individual 7 have? Remember the Marfan's trait is dominant. mm MM MN Mmk

## Step 1<br />The problem involves understanding the inheritance of traits, specifically the Marfan's trait, which is dominant. The genotype of both individuals is given as Mm. <br /><br />## Step 2<br />The genotype Mm consists of one dominant allele (M) and one recessive allele (m). The dominant allele (M) is responsible for the Marfan's trait.<br /><br />## Step 3<br />When 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.<br /><br />## Step 4<br />The Punnett square for this cross would look like this:<br /><br />| | M | m |<br />|---|---|---|<br />| M | MM | Mm |<br />| m | Mm | mm |<br /><br />## Step 5<br />From 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.<br /><br />## Step 6<br />Therefore, 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.
