- Notation: D = disease allele at gene d = wild-type allele at gene Let’s provide some information about each MOI. AD: Each of the F1 parents is heterozygous for the D allele. SLR: The observed F2 data are the offspring from an F1 cross where the father is affected (disease) and the mother is an unaffected carrier (wild-type, or WT). That is, the mother’s genotype has one disease allele and one WT allele in it. In Table 1, I provide the observed data counts (in dark blue). Notice that I stratify by gender.

This is the letter you will use when recording the genotypic information for each trait.Read through the descriptions of each trait and determine which phenotype you express. Record your phenotypeNext, determine your genotype. If you express the dominant phenotype, you cannot determine the second allele you carry, so you must list the two possible genotypes. Record this. Question: Widow’s Peak (W): A hairline that forms a downward point in the middle of the forehead is caused by a dominant allele. A smooth hairline is caused by a recessive genotype.

Record your phenotypeNext, determine your genotype. If you express the dominant phenotype, you cannot determine the second allele you carry, so you must list the two possible genotypes. Record this. Question: Eye color (B): Inheritance of eye color is controlled by multiple genes, but people having the homozygous recessive genotype have blue eyes.
