HELP FAST I GIVE BRAINLIEST + 15 POINTS!!! Follow the directions to convert the analog sound wave into a digital signal. The lin
es on the grid intersect at various points (x, y). For each whole-number value of x, find the intersection point that is closest to the wave. Draw a small circle on that point, and record its y-value. The circles for the x-values 0 through 3 are already done for you. Draw circles for the x-values 4 through 18. In a textbox, write down all 19 y-values obtained by sampling the wave.
Answer:B) homologous chromosomes trade pieces of dna
Explanation:
Crossing over occurs between two homologous chromosome of sisters chromatid. Crossing over leads to exchange of genetic material between the two sister chromatids leading to recombination.
Crossing over is essential for the normal segregation of chromosomes during meiosis. Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.
