WebThe expected genotypic ratio refers to the one that was calculated by Mendel during his experiments on inheritance. The most common method of calculating the genotypic ratio is by making a Punnet square with zygotes derived from the F1 generation.

WebA 3:1 phenotypic ratio in the F2 generation of a monohybrid cross represents this genotypic ratio: 1:2:1 Choose statements that correctly refer to components of Mendel's five-element model (please note that the answers use the modern term gene instead of factor). Parents transmit genes to offspring. Alternative forms of genes are called alleles. Web9. apr 2024 · Higher-order polyploid strains tended to have lesser seeds than the tetraploids (average: 6.63–1.64), except for P5-7. P5-7 had an abundance of seeds (average: 21.62). Additionally, the ratio of sterile seeds was 77% in diploids and less than 16% in all the other ploidies. In 2024, the number of seeds was 13.2 in diploids and 13.5 in tetraploids.
