17. Brainpop Heredity

18. Punnett Squares Punnett Square – a chart used to show four possible ways that genes can be combined when passed from parents to offspring as a result of reproduction. Father’s genotype – on side of square Mother’s genotype – on top of square Offspring Possibility #1 Offspring Possibility #2 Offspring Possibility #3 Offspring Possibility #4 Mother’s Genotype Allele 1 Father’s Genotype Allele 2 Allele 1

19. Punnett Square – example Top left box = Mother’s first allele, Father’s first allele Top right box = Mother’s second allele, Father’s first allele Bottom left box = Mother’s first allele, Father’s second allele Bottom right box = Mother’s second allele, Father’s second allele
