Document Summary
Dichotomous keys: allow for the comparison of potential breeding of two individuals, and the potential characteristics their offspring would carry. Genes: a string of dna or rna that determines a certain trait. They are responsible for the colour of your hair, your height, your eye colour, etc. Several alleles can belong to the same gene, but are varied in their ability for expression of what that gene is. Ex: red haired, blonde haired, black haired, auburn hair alleles all belong to a hair colour gene. Homozygous: homo (same)- the alleles are the same for the particular gene. Heterozygous: hetero(different)- the alleles are different for that particular gene. Genotype: the genetic make up of that gene: determines phenotype. Phenotype: the visually observable trait of that gene: cannot always determine genotype based on appearance. An example of mendel"s law, or how the ratios of offspring are determined:
