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.

- Analysis of Autosomal Recessive and Dominant Traits Huntington disease is a rare, fatal disease that usually develops in the fourth or fifth decade of life. It is caused by a single autosomal dominant allele. A phenotypically normal man in his twenties who has a 2-year-old son of his own learns that his father has developed Huntington disease. What is the probability that he himself will develop the disease? What is the chance that his young son will eventually develop the disease?Click on the link: https://www.dailymail.co.uk/news/article-4168946/Mum-world-s-black-woman-two-white-babies.html#ixzz4hvs1FUeM.Links to an external site. This case explores how skin color is inherited in humans, presented in the story of Catherine and Richard Howarth whose children are surprisingly light skinned compared to their Nigerian mother. Based on what you have learned about polygenic inheritance, explain how Richard and Catherine Howarth were able to produce light-skinned babies. Are the odds indeed 1 in a million? Include possible genotypes of the couple and their children to support your argument.Pseudohypertrophic muscular dystrophy is an inheriteddisorder that causes gradual deterioration of the muscles. It isseen almost exclusively in boys born to apparently unaffectedparents and usually results in death in the early teens. Isthis disorder caused by a dominant or a recessive allele?Is its inheritance sex-linked or autosomal? How do youknow? Explain why this disorder is almost never seen in girls.

Freckles (F) is dominant over the recessive trait of no freckles (f). (It is important to note that this example of mid-digital hair and freckles cannot be explained with simple genetics, but for the purpose of this question, assume that it can.)A woman that is heterozygous for freckles and has no mid-digital hair is married to a man with no freckles that is heterozygous for mid-digital hair. The couple is expecting a child. Draw a Punnett square of this cross then answer the following questions: What is the probability that their offspring will have mid-digital hair? What is the probability that two offspring in a row will have no freckles? What is the probability of two offspring in a row having mid-digital hair and freckles?
