Punnett Square definition
Homozygous
Punnett Square showing NO VARIATION of offspring genotypes compared to parents
Differences among individuals in the composition of their genes or other DNA segments
Organisms with better genes survive and those alleles get passed onto offspring
Example: GG or gg
Type of reproduction that leads to variation of traits
A chart that shows all the possible combinations of alleles that can result from a genetic cross of 2 parents
Type of reproduction that leads to NO variation of traits
Causes of genetic variation
Example: Gg
A change in a gene/allele base pair that causes a new allele to be formed that can be passed to the offspring
