This means that the phenotypic ratio (which estimates how many times one phenotype correlates with another) in the F2 generation is 3 purple : 1 white. Mendel performed thousands of monohybrid crosses over years of research, and they all yielded similar results, no matter which characteristic he...
Plant and animal breeders sometimesdo a test cross in which the individual showing the dominant phenotype is crossed with one showing the recessive phenotype. The recessive phenotype is used because it has a known genotype. The results of the test cross can indicate the genotype of theparent ...
crossbreed,hybrid,cross- (genetics) an organism that is the offspring of genetically dissimilar parents or stock; especially offspring produced by breeding plants or animals of different varieties or breeds or species; "a mule is a cross between a horse and a donkey" ...
Monohybrid Cross: F2 generation By Regina Bailey Should the F1generation be allowed to self-pollinate, the potential allele combinations will be different in the next generation (F2generation). The F2generation would have genotypes of (GG, Gg, and gg) and a genotypic ratio of 1:2:1. One-fo...
Using the counts from the previous step, you can determine the phenotype ratio. A phenotype is the physical characteristic of the gene, such as hair or eye color.[6] Assuming the trait shows complete dominance, the heterozygous genotype (the cross showing dissimilar pairs of genes for a heredi...
