What are the phenotype percentages of offspring with genotypes AA and aa?

Back

75% Brown fur and 25% White fur

Front

What is the genotypic ratio of offspring from a cross between AA and aa?

Back

25% AA: 50% Aa: 25% aa

Front

What is the difference between homozygous and heterozygous?

Back

Homozygous has identical alleles (e.g., AA or aa), while heterozygous has different alleles (e.g., Aa).

Front

What is the role of DNA in genetics?

Back

DNA stores and transmits genetic information.

Front

What is the significance of the Punnett square in genetics?

Back

It predicts the genotypes and phenotypes of offspring from genetic crosses.
