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

these traits are not linked, what proportion of the F2 offspring will be expected to display the dominant phenotype for eye color and recessive phenotype for wing shape

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>

Is mitosis or meiosis preceded by interphase?
labwork [276]

Answer:

Meiosis is preceded by an interphase consisting of three stages.

Explanation:

The S phase is next, during which the DNA of the chromosomes is replicated. This replication produces two identical copies, called sister chromatids, that are held together at the centromere by cohesin proteins.

jak nazywa sie proces w którego wyniku powstaja chmury : a) parowanie b) skraplanie c) krzepiecie d) topienie​
ahrayia [7]

Answer: b) skraplanie

Explanation:

Condensation is the process by which clouds are formed. It happens after water has been evaporated off of the earth's surface. As the water vapor rises up, temperatures will begin to get colder which will end up condensing the vapor into water droplets.

These water droplets will then combine to form clouds and as the process continues to happen, the clouds keep getting bigger until they become too big to remain in the atmosphere and then fall as rain.
