Law of independent assortment

Mendel’s Laws Law of Independent Assortment Alleles sort independently of one another Alleles on one chromosome don’t control the inheritance of alleles on another chromosome Mendel made this conclusion after performing dihybrid crosses Crosses with two traits

Dihybrid Crosses A - green seeds, a – yellow seeds B – purple flowers, b – white flowers AaBb x Aabb AB Ab aB ab

Dihybrid Crosses AB Ab aB ab AABb AAbb AaBb Aabb aaBb aabb

Dihybrid Crosses Phenotypic Ratio - 6 green seeds, purple flowers 6 green seeds, white flowers 2 yellow seeds, purple flowers 2 yellow seeds, white flowers

Sample Problems In peas, tall plants are dominant to dwarf plants and round seeds are dominant to wrinkled. A heterozygous tall, round seed plant self-fertilizes. What would the genotypic and phenotypic ratios be?
