4. Would a mutation in the DNA of a skin cell be passed on to an organism's offspring? a. Yes, because any change to the DNA is passed on to the offspring b. Maybe. Sex cells only use half of the body's genetic code. It might get the copy of a gene that wasn't mutated. c. No. Only mutations that occur in the gametes (sex cells) are passed on to the offspring d. Without knowing the animal, it would be hard to tell whether or not the mutation would be passed on.
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.
