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.
Short-term human ecological change is caused by habitat destruction, deforestation, wildlife hazards, pollution and non-sustainable harvesting. ... Deforestation, climate change/global warming, ozone layer destruction, and the mass-extinction of plant and animal species. Not sure about your question, but I hope this helped
The answer is; Pepsin
Pepsin is first secreted by the chief cells of the stomach wall and the inactive precursor called pepsinogen. When pepsinogen interacts with the acidic environment of the stomach due to hydrochloric acid, it is turned to pepsin. The pepsin breaks down large protein molecules to smaller molecules.
Answer:
the null hypothesis and the alternative hypothesis.
Explanation:
null contains a statement of equality (greather than or equal to, less than or equal to, equal to) and the alternative is the complement of the null hypothesis statement that must be true if H0 is false and it contains a statement of strict inequality (greater than, less than, not equal to)
The frequency of alleles in a population that is in hardy-Weinberg equilibrium
A) changes in each successive generation
<u>B) is less important than the frequency of genotypes </u>
C) shows evidence of the process of natural selection
D) remains the same over several generations
