Different forms of a trait that a gene may have (represented by a letter) Allele

The study of how traits are inherited Genetics

What has different alleles from each parent? (Tt) Hybrid (also called heterozygous)

The gene that dominates (shows up) upper case letter Dominant Gene (purple color)

A gene that may be covered by a dominant gene (lower case letter) Recessive (white flower)

This is used to predict genetic outcomes. Punnett Square

The Genetic makeup of an organism is it’s Genotype BB, Bb, bb

The Physical appearance of an organism is it’s Phenotype (Purple or White Color)

The SAME genes (AA, aa)

Different Genes (Aa) Heterozygous
