Document Summary

Each chromosome is made up of dna. They have a specific set of biochemical instructions. Genotype is ones complete set of genes (genes you have) Phenotype is gene environment interaction (expression of those genes) Karyotype= take a single cell from your body and come up with your genetic. Eye colour: blue eyes are recessive , brown eyes are dominant. Pairs of alleles can either be homozygous or heterozygous. Dominant allele: rare, not both alleles have to be the same. Recessive allele: you have to get the allele from both parents, must be the. Incomplete dominance: one allele doesn"t dominate the other completely. Complete dominance: one is enough (brown eyes) Codominance is a special type of incomplete dominance, Heterozygous individual simultaneously expresses both allele phenotypes (sickle cell trait) (wavy hair) same equally. (one brown eye one blue eye, abo blood type) Both parents must have at least one mutated allele of the pah gene.
