Gregor Mendel - Father of Genetics. Studied pea plants., Reginald Punnett - Created the punnett square., Punnett Square - shows all the genes that parents can give to their offspring (babies)., Gene - Small piece of DNA, Allele - Different forms of the same gene., Dominant - The stronger allele. Always shows up, even if a weaker gene is there too. We use a capital letter to show it., Recessive - The weaker allele. It will hide if a stronger one is there too. We use a lowercase letter to show it., Inherit - When things are passed down from a parent to a child., Meiosis - making four special cells to make offspring., Heterozygous - When two alleles are different. Like Bb., Homozygous - When two alleles are the same. Like BB (dominant) or bb (recessive)., Phenotype - This is what you actually look like. This is like brown hair or a purple flower., Genotype - The two alleles or genes you have. Like Bb or aa.,
