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.

There are many disease causing organisms and genetic disorders that can make life difficult. As you read the chapter, be thinking about your family history of genetic disorders, how these disorders are passed on through generations, and what types of testing can be done to look for these alleles. In this exercise you will reflect on the pros and cons of genetic testing and how it may affect you. Please remember to add a question to engage your classmates in the discussion.

Complete this flowchart to show how different alleles can result in different characteristics. different sequence of in transcription > different sequence of in a protein translation > different structure and function of the protein (e.g. normal enzyme vs. defective enzyme) > different characteristics (e.g. normal color vs. albino) In this section, you will analyze how different alleles of the hemoglobin gene can result in sickle cell ar vs. normal health. ***19. Compare the nucleotide sequence in the "Beginning of Normal Hemoglobin Gene" vs. the "Beginning of Sickle Cell Hemoglobin Gene". What is the only difference?"How to Solve Genetic Problems" Using Letters for Alleles For convenience, the genes of an allele pair are usually symbolized by a letter from the alphabet. A large letter is used for the dominant trait and a small letter for the recessive trait. When we want to describe the genotype of an organism, we use both letters to represent the alleles inherited from the parents. For example, free earlobes is a dominant allele and attached earlobes is recessive. You would use a capital "F" to indicate the dominant allele and a small “f" to indicate the recessive allele in describing an individual. 1. Write the three genotypes for earlobe attachment as it applies to the following individuals. a. Heterozygous b. Homozygous Dominant c. Homozygous Recessive 2. When it comes to symbolizing incomplete dominance with letters, it is best to use the letter "C" for one allele and "C'" for the other allele. List the three possible genotypes for hair type. a. Curly b. Wavy c. Straight. Why not use a small…
