2. Microsatellites DNA is various number of short nucleotide repeat presence in our genomic DNA. If John’s father has microsatellites of 9 repeats and 6 repeats, his mother has 6 repeats and 5 repeats. What could be the combination of microsattelites in John’s genomic DNA? ① 9 repeats and 6 repeats ② 15 repeats and 12 repeats ③6 repeats and 6 repeats ④ 9 repeats and 5 repeats ⑤12 repeats and 14 repeats (A) ①② (B) ①③④ (C) ②④ (D) ③ ④ ⑤ (E) ④ ⑤
