WebWhat is the genotypic ratio of this monohybrid cross? 1:2:1. 9. What are the phenotypic and genotypic ratio for a cross between a homozygous dominant individual and a heterozygous individual? Construct a Punnett Square. The phenotypic ratio would be 1:0 and the genotypic ratio would be 1:1. 1. WebThese are the offspring ratios we would expect, assuming we performed the crosses with a large enough sample size. Because of independent assortment and dominance, the 9:3:3:1 dihybrid phenotypic ratio can be collapsed into two 3:1 ratios, characteristic of any monohybrid cross that follows a dominant and recessive pattern.

Of the sixteen possible allele combinations: Nine combinations produce offspring with both dominant phenotypes. Three combinations each produce offspring with one dominant and one recessive phenotype. One combination produces a double recessive offspring.

Web16. jún 2024 · So, the monohybrid cross-ratios are as follows: The genotypic ratio for monohybrid cross: 1:2:1 ratio The phenotypic ratio would be 3:1 ratio. This is based upon the rule of dominance, i.e., phenotypically, R being dominant trait, RR as well as Rr combinations would appear as the dominant trait. WebThese types of crosses are useful in weeding out hidden recessive alleles from your unknown. Remember the information on recessives if you don't remember anything else. By knowing the recessive, you automatically know both the phenotype and genotype. In the monohybrid cross, a testcross of a heterozygous individual resulted in a 1:1 ratio.
