F1 Generation Cross F2 Generation (at least 500 flies) F1 red-eyed females x white-eyed males 50% of females are red-eyed and 50% are white- eyed 50% of males are red-eyed and 50% are white-eyed 21. The best explanation for the red-eyed F1 females is (A) mutation (B) culture contamination (C) dominance (D) multiple loci (E) sex-influenced traits 22. There are white-eyed females in the F2 generation because (A) white is a dominant allele (B) the white allele is autosomal (C) a mutation has occurred (D) these F2 females have two white alleles (E) the white allele is located on the Y chromosome 23. Which of the following best describes the mode of inheritance of eye color in the white culture? (A) Autosomal (B) Dominant (C) Located on the Y chromosome (D) Sex-linked (E) Lethal
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.
