O True O FalseQuestion 3 Anna (who produces eggs) and Syed (who produces sperm), have a child with Down's syndrome that results from trisomy of chromosome 21. Using a microsatellite sequence on chromosome 21, you run a gel. The gel imaged is attached; darker bands indicate signals of twice the intensity. If a nondisjunction event occurred in Anna during meiosis I, which lane (A, B, C, D) best fits the genotype of their child? Explain your choice, clearly identifying why that lane is correct and why the other lanes are incorrect. Assume no recombination.QUESTION 10 Click directly on the chromosomal location named 2q22.
