How many groups of phenotypes can be distinguished in the offspring of hybrid parents? Write down the designations of the genotypes corresponding to the phenotype groups, make a conclusion about the phenotypic similarity of organisms with different genotypes.
Four groups of phenotypes are smooth yellow, wrinkled yellow, smooth green and wrinkled green seeds.
Yellow smooth: AABB, AABb, AaBb.
Yellow wrinkled: Aabb, Aabb.
Green smooth: aaBB, aaBB.
Wrinkled green: aabb.
Homozygotes for the dominant feature and heterozygotes have the same phenotype.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
