Gregor Mendel studied inheritance of traits in pea plants. He proposed a model where pairs of "heritable elements," or genes, specified traits.
Genes come in different versions, or alleles. A dominant allele hides a recessive allele and determines the organism's appearance.
When an organism makes gametes, each gamete receives just one gene copy, which is selected randomly. This is known as the law of segregation.
A Punnett square can be used to predict genotypes (allele combinations) and phenotypes (observable traits) of offspring from genetic crosses.
A test cross can be used to determine whether an organism with a dominant phenotype is homozygous or heterozygous
