F1 Monohybrid Cross

Both parent plants are heterozygous ss for an allele that determines seed shape. Monohybrid cross definition a monohybrid cross is the hybrid of two individuals with homozygous genotypes which result in the opposite phenotype for a certain genetic trait the cross between two monohybrid traits tt and tt is called a monohybrid cross monohybrid cross is responsible for the inheritance of one gene. Presence of the dominant allele s in homozygous ss or heterozygous ss plants results in spherical seeds.
f1 monohybrid cross

For a monohybrid cross of two true breeding parents each parent contributes one type of allele.

F1 monohybrid cross. Modern scientists now describe the cross of mendels f1 generation as a monohybrid cross. In this case only one genotype is possible in the f1 offspring. The figure above represents a monohybrid cross of f1 hybrid plants. This cross only examined one trait however many more traits can be observed at once.

The individuals in the cross all had one allele for green pods and one allele for yellow pods making them hybrids. Spherical seeds are the dominant characteristic mendel collected the seeds from this cross grew f1 generation plants let them self pollinate to form a second generation and analyzed the seeds of the resulting f2 generation. Homozygous recessive ss plants have dented seeds. The results that he obtained and that you would predict for this experiment are.

All offspring are yy and have yellow seeds.
