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.

A way to prevent spoilage of unsaturated fats and make them solid at room temperature is to change their fatty acids chemically through: Hydrogenation.
- Hydrogenation is a chemical reaction between molecular hydrogen and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds.
- Hydrogenation reactions are extensively used to create commercial goods.
- Hydrogenation is used in the food industry to make a large variety of manufactured goods, like spreads and shortenings, from liquid oils. This process also increases the chemical stability of products and yields semi-solid products like margarine.
- Hydrogenation is also used in coal processing. Solid coal is converted to a liquid through the addition of hydrogen. Liquefying coal makes it available to be used as fuel.
