AaBb x AaBb. Both parents express the dominant phenotype for both traits.
The resulting offspring phenotypic ratio is 9:3:3:1. What does this indicate?
these two genes are on non homologous chromosomes and independently assort
during meiosis
these two genes are linked and on the same chromosomes and can NOT
independently assort
some of the offspring are the result of crossing over
O there is NOT random fertilization happening.
