are segments of DNA that code for proteins or RNA molecules. These genes are the genetic material that is passed down from generation to generation in all species. The individual DNA segments each individual carries are known as their alleles or genotype. When two alleles are identical they are homozygous and when they are different they are heterozygous. These alleles are expressed physically through what is known as the phenotype. An example of a phenotype of a gene is hair color‚ which may be

5. Based on the data obtained‚ is the most likely mode of inheritance in Case 2 autosomal or sex–linked? Explain. Sex linkage‚ because the pattern of inheritance is not the same for males and females. 6. From the data presented‚ what is the genotype of the parental (before the F1 generation; not shown here) generation? X+X and X+Y 7. Determine the degrees of freedom. This is the number of categories (red eyes or sepia eyes) minus one. For the data in Case 1‚ what is the number of degrees of
