Punnett squares are important tools for understanding how traits are passed down in families. They help scientists see and figure out the chances of babies getting certain traits from their parents.
Here are some key points:
Genotype Ratios: When two parents, both carrying different versions of a gene (let's say ), have kids, the expected genetic makeup of those kids is in a 1:2:1 ratio. This means 1 out of 4 might have one type of gene, 2 out of 4 might have another type, and 1 out of 4 could have a different type.
Phenotype Ratios: The looks or traits that show up (called phenotypes) will have a ratio of 3:1. This means there is a 75% chance that the kids will show the dominant traits.
In simple terms, Punnett squares help us figure out the chances of traits being inherited effectively.
