The phenotypic ratio resulting from a dihybrid cross showing independent assortment is expected to be: 9:3:3:1.
<h3>What is a phenotype ratio?</h3>
- The phenotypic ratio refers to the proportion of offspring that exhibit a specific trait or set of traits. A test cross can be used to ascertain the frequency of a trait or trait combinations that will manifest themselves based on the genotypes of the progeny.
- The ratio of various phenotypes found in a cross's progeny is known as the phenotypic ratio. Comparisons using numbers are ratios. For instance, the proportion of apples to oranges would be 3:2 if someone had three apples and two oranges.
- We examine the alleles of the parent organisms and predict how frequently the offspring will exhibit those genes to determine a phenotypic ratio. Most of the time, we are aware of the expression and appearance of the alleles.
- Phenotypes include things like height, wing length, and hair color. In addition to measurable traits that may be observed and tested in a lab, phenotypes also include blood cell or hormone levels.
