A geneticist is studying two traits in the fruit fly - eye color and wing shape. They perform a dihybrid cross. If the genes for
Len [333]

Answer:

3/16

Explanation:

<u>According to Mendel's law of independent assortment of genes, when a dihybrid cross involves two genes that assort independently and one of the parents is dominant for the two genes and the other is recessive, the phenotypic ratio of the offspring at F2 would be 9:3:3:1</u>. The proportion of the offspring with the dominant parental traits would be 9/16, those with the recessive parental traits would be 1/16, while those with mixed traits would be 3/16 each.

Assuming the eye color is represented by E and the wing shape is represented by W. At F2

     EeWw    x    EeWw

E_W_ - 9/16 (dominant for both eye color and wing shape)

E_ww - 3/16 (dominant for eye color and recessive for wing shape)

eeW_ - 3/16 (recessive for eye color and dominant for wing shape)

eeww - 1/16 (recessive for both eye color and wing shape)

<em>Hence, the proportion of the offspring with dominant phenotype for eye color and recessive phenotype for wing shape would be </em><em>3/16.</em>

the diagram below represents levels of glucose and insulin found within the bloodstream of a healthy person
Makovka662 [10]
The increase in insulin level following an increase in glucose level in the blood can best be explained by A FEED BACK MECHANISM THAT REGULATE THE BLOOD GLUCOSE LEVEL.
Insulin is an hormone that is secreted by the pancreas and it functions by regulating the amount of glucose that is found in the blood. When the level of glucose in the blood is higher than normal, insulin interfere by converting the excess glucose into glycogen. The glycogen is stored in the liver and in the skeletal muscles and they will only be converted back into glucose, if the level of glucose in the blood is lower than normal.

Genetic drift occurs when people move into or out of a population. <br> a. True <br> b. False
Ede4ka [16]
The statement would be considered to be B. False, because genetic drift occurs when different genotypes in smaller populations have a chance of disappearance. This is due to the species either dying off or not reproducing with others, so the genotype doesn't spread to offspring, because the species didn't have offspring.
