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.
True or False: When a geneticist hands you a patients file with 47,XX + 13, then he or she is considered normal.

- The identity of Kim's biological father is unknown, but it is thought to be either Kevin or Thomas. To determine which of the two men it is, blood typing of all the persons involved was performed. Here are the results of the blood tests, including the phenotypes and possible genotypes of each person: Rachel (mother) Type AB; genotype IA, IB Kim (child) Type A; genotype is either IA, IA (if homozygous) or IA, i (if heterozygous) Kevin (alleged father #1) Type A; genotype is either IA,IA if homozygous or IA, i if heterozygous Thomas (alleged father #2) Type O; genotype is ii There are 2 DNA bands in the "fingerprint" of each person tested: mother, child, alleged father 1, and alleged father 2. Why are there two bands for each person and not three?Pedigree chart *questions are on the imagePedigree chart *questions are on the image attached
