C. Give the genotypic and phenotypic ratios 1. Hemophilia is a disease caused by a gene found on the X chromosome. The recessive allele causes the disease. Tall (T) is dominant over short (t). A homozygous tall female carrier marries a short hemophiliac male. Predict the genotype and phenotype of their offspring. 2. In mice, the ability to run normally is a dominant trait. Mice with this trait are called running mice (R). The recessive trait causes mice to run in circles only. Mice with this trait are called waltzing mice (r). Hair color is also inherited in mice. Black hair (B) is dominant over brown hair (b). 2 heterozygous running, heterozygous black mice were crossed. Give the genotypic and phenotypic ratios of their offspring.

Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
