punnet squares

• Reginald Punnet compares 2 alleles from the mom and dad to predict anything genetically for the child. Humans get 2 copies of genes (from mom + dad) and it determines the heterozygous dominant and homozygous dominant / recessive gene.
• The probability that an individual will have a certain phenotype is determined by the number of possible combinations of alleles.
• A monohybrid cross involves two individuals with different versions of one trait, such as eye color or flower shape
• In a dihybrid cross, there are two traits being inherited at once, such as flower color and petal shape
• Homozygous dominant is any alphabet dominant (BB). Homozygous recrecessive is based on the trait of the same gene that is recessive (bb). Heterozygous recessive has more genetic variation because it has 2 alleles (Bb).
