How and why does DNA change during meiosis

kotykmax [81]

Answer:

When recombination occurs during meiosis, the cell's homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome breaks in the exact same location, leaving two free ends. Each end then crosses over into the other chromosome and forms a connection called a chiasma.

Papessa [141]

Answer:

<em>The correct option is C. Mendel's laws of segregation and independent assortment</em>

Explanation:

Mendel's law of segregation states that the two alleles of a gene pair segregate individually at the time of the formation of gametes. They also unite independently during the time of fertilization. We can see that in the scenario mentioned in the question, the alleles segregate independently.

Mendel's law of independent assortment states that the alleles of different genes assort independently at the time of gamete formation. Different traits are passed from the parents to the offsprings irrespective of one another.

The answer is: Wind direction impacts the design of airports, including the location and orientation of the runway.

<h3>Further explanation </h3>

Examine the accompanying wind rose diagram. Based on the information shown, determine the correct answers to the following questions.

Drag the appropriate labels to their respective targets. Note that there are twice as many blanks as answer choices. In other words, only half of the targets need to receive a label. Pay attention to the color coding and think carefully about the best position for each label when multiple locations seem possible.

The answer is: Wind direction impacts the design of airports, including the location and orientation of the runway. This relationship explains why planes circle above an airport so they can land in the correct orientation, and why they reorient themselves after taking off in a direction other than the direction they wish to fly. In our example, the longest spoke in the wind rose diagram indicates prevailing winds are coming from the NE and blowing toward the SW. Therefore, the correct orientation for the runway is along this path, with planes taking off in the SW to NE direction. This wind pattern can be found where NE trade winds are located.
