Punnett square science sticker / decal
Regular price $3.50
Look y’all, I made a PUN...nett square 🤣 An easy way to calculate the likelihood of a child inheriting a specific trait from their parents is with a #PunnettSquare! It is a graphical representation of possible offspring genotypes (gene combinations) and phenotypes (appearances). This sticker uses peas as an example, however, Punnett squares can also explain other traits - like why you might have green eyes but your sibling’s are brown. They can also give the odds of a parent passing along genetically inherited diseases like #CysticFibrosis, #Dwarfism, and #HuntingtonDisease! These squares are still used by genetic counselors today. Genes come in different forms, called alleles. One #allele is inherited from each parent. A dominant allele (X) has all the power - it determines how the offspring will look. Like their name implies, they #dominate over recessive alleles (x)! Recessive traits are therefore hidden unless they are inherited from both parents. A pair of alleles can be #homozygous, meaning both alleles are the same - XX or xx; or they can be #heterozygous - Xx. Notice how all the offspring with the dominant allele ‘X’ are the same color!
