A monohybrid cross is a type of genetic cross between two individuals with homozygous genotypes of a single character or trait, often resulting in an opposite phenotype.
For example, cross true breeding plants with yellow, round seeds to true breeding plants with green, wrinkled seeds will yield an F1generation of all yellow, round seeds.Dihybrid Cross: First CrossP1P1F1Dihybrid Cross: First CrossWhat does the phenotype of the F1generation tell you? Yellow ...
