First 22 pairs called autosomes: same size, 23rd pair determines sex of child. Xx = girl and xy = boy. When alleles are different there called heterozygous. Genotype: complete set of gene"s, person"s heredity. Phenotype: genetic instructions with environmental influences, individual"s physical, behavioural, and psychological features; height, weight, eye colour, hair colour. Dominant genes: expressed, chemical instructions are followed, can be seen in both homo and heterozygous.
