Karyotype- Full set of 23 pairs of homologous chromosomes arranged in pairs and photographed through a microscope
Mutation- When DNA is copied for cell division in some cases the order of chemicals are incorrect or part of a chromosome is missing
A mutation is normally harmful towards the organisim and may therefore cause genetic diseases or death (colour-blindness and cystic fibrosis)
DNA fingerprinting can be used to compare a section of DNA from a person's body. A gel will help the sections form a pattern. Every persons is unique (not identical twins). The pattern can be useful in finding a matching suspect or how people are related
Inheritence
Homozygous: Having two of the same alleles (dominant or ressesive)
Heterozygous: The two alleles will be different from one another.
