Punnett Square
Can help us predict the certain outcome of traits in an organism; shows the probability of a trait happening as well as all of the possibilities.
genotype
The genetic makeup of a particular trait in an organism and shows the dominant and/or recessive alleles that make up the gene (ex. Tt or BB or cc, etc.).
heterozygous
The two alleles that make up a gene are different (ex. a dominant allele and a recessive allele - Bb, Cc, Ff).
homozygous
The two alleles that make up a gene are similar (ex. two dominant alleles or two recessive alleles - BB or bb).
