Answer:
Epistatic gene interaction
Explanation:
A dihybrid cross is a mating or breeding experiment involving two organisms that are identically hybrid of two traits/genes. According to Mendel's law of independent assortment of genes, a dihybrid cross should yield progenies with 9:3:3:1 phenotype ratio. However, this is not always the case.
Sometimes in nature, a single gene can influence the emergence of two or more traits or phenotype and cause a shift away from the normal 9:3:3:1 phenotypic outcome in a dihybrid cross. This is known as <em>pleiotropy</em>.
Also, two or more genes can influence the appearance of a single trait or phenotype. Allelic or non-allelic genes can interact in a number of ways to influence a trait and cause a shift away from independent assortment. This is referred to as <em>epistasis or epistatic gene interaction</em>.
In the species of rodent in question, it has already been reported that two genes determine the coat color and a dihybrid cross produced a phenotypic ratio that is different from 9:3:3:1. This is definitely an epistasis or epistatic gene interaction.
<h2>Answer with explanation:</h2>
The correct option is B which is 100°c.
- Boiling point of a substance is a specific temperature point at which the vapor pressure of the liquid equals to the external pressure.
- The temperature of the liquid increases till the boiling point, after that point the given heat is used to break the bonds in the liquid molecules to convert them into vapors.
- After 100°C the water will convert into vapors.
The hypothalamus acts as the connector between the endocrine and nervous systems to achieve this.
Answer: In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water.
Explanation:

c.Nitrogen base
d. Adenine, Gaunine, cytosine, Thymine.
