Phenotypic ratio: 1:0
genotypic ratio: 1:1
Mendelian traits
Independent Assortment
This is the random arrangement of homologous chromosome pairs down the center of a cell in metaphase I. Inheritance of a gene on one chromosome does not influence inheritance of a gene on a different chromososme. (Mendel's second law)
Law of Segregation
The distribution of alleles of a gene into seperate gametes during meiosis (Mendel's first law)
Genotype - The allele combinations in in an individual that cause particular traits or disorders
Phenotype - The expression of a gene in traits or symptoms
dominant - A gene variant expressed when present in one copy
recessive - An allele whose expression is masked by another allele
homozygous - having two identical alleles of a gene
heterozygous - having two different alleles of a gene
