Dominant and recessive alleles are important in how traits are passed down from parents to children. Let’s break it down:
Dominant Alleles: You only need one copy of a dominant allele for it to show up. For example, if 'A' is dominant over 'a', then 'A' will be seen whether you have two 'A's (AA) or one 'A' and one 'a' (Aa).
Recessive Alleles: These need two copies to show up. This means you have to have 'aa' to see the recessive trait. If there’s one dominant allele, the recessive trait will not be visible.
Punnett Squares are really useful tools that help us predict traits in offspring. By using these squares, we can explore the possible combinations of alleles from parents. It’s fascinating to see how these combinations can create different traits in the next generation!
