E hypothetical genes are arranged on a chromosome in the following order: G--H--I--J--K. Which two genes are most likely to have a crossover occur between them?

The correct answer is - G and K.

Explanation:

Crossing over is the process that causes recombination by the genetic exchange in the nonsister chromatids of a homologous chromosome during the meiotic division in the cell.

The chances of the cross over in between two genes are directly proportional to the distance present in between the genes. The farthest the genes the chances of the crossover are more in these. So, there is in question the provided question has a chromosome with the greatest distance between G and K chromosome.

Thus, the correct answer is - G and K.

explanation:

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
