Punnett squares are a great way to help us understand genetics! They make it easier to see how different traits are passed down.
Here are some key ideas to know:
Dominance: A dominant allele is strong and can hide the effect of a weaker allele, called a recessive allele.
For example, if we combine a tall pea plant with a strong gene (TT) and a short pea plant with a weak gene (tt), all the baby plants will be tall (Tt).
Recessiveness: Recessive traits only show up when both alleles are recessive.
In our case, the only plants that would be short have to have two weak genes (tt).
When you draw a Punnett square, it helps you see the different traits that the baby plants might have. It’s a simple way to understand genetics!
