Gametes
the passing on of physical or mental characteristics genetically from one generation to another
Heredity

Genotype
A disease caused by an abnormality in an individual's genome
Genetic Disease
a form of asexual reproduction in which a new organism develops
Budding
Different forms of a gene
Alleles
