Genetics

What are genetics? Genetics are the study of how traits are inherited through the interactions of genes. There are Phenotype, Genotype, Dominant allele, Recessive allele and X-Linked trait. A phenotype is the expression of a genotype in the appearance or function of an organism; the observed trait. A genotype is the genetic makeup of an organism. A dominant allele is a trait that is visible in a heterozygous organism. A recessive allele is a term used to describe an allele or trait that is masked by a dominant allele or trait. an X-linked trait is a trait that is on the X-chromosomes and there is one X-chromosome for the male and two for the females. If a male has something on there X-chromosome then they have what ever it is they can never be a carrier, but females can be carriers and affected because they have two X-chromosomes. Phenotype and genotype are different because one you can see the persons features. So like if two parents were to have blue hair then you look at there kids and you see blue hair that is a phenotype.
