Answer:
Because of the difference in the genetic makeup of those with the beak shape, their population evolves to a higher level of adaptation. I think it should be fewer mutated.
Answer:
d) A and B above.
Explanation:
Triacylglycerols are the simplest form of lipids comprised of fatty acids. Triacylglycerols are also called as fats or neutral fats. Each molecule of triacylglycerol is composed of three fatty acids bonded to the single glycerol molecule.
Each of the three fatty acids of triacylglycerol is bonded to glycerol in an ester linkage. The main function of triacylglycerols is to serve as energy storage form and provide insulation to eukaryotic cells.
D) if the tubes of the tracheal system in insects were longer, this would cause oxygen to reach the cells more slowly due to the distance factor
Answer:
This is an example of recessive epistasis.
Explanation:
Gene interactions happen between genes at different levels and have implications in the phenotypic expression, causing a wide genetic variability.
Epistasis means "interruption" and refers to interactions between genes located in <em>different loci in the same chromosome</em>. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". When the epistatic gene is recessive, the interaction is known as "recessive epistasis".
Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.
In recessive epistasis, the proportion is 9:3:4.
