Answer:
Mother, meiosis II
Explanation:
Red-green color blindness is a human X-linked recessive disorder. A young man with a 47,XXY karyotype (klinefelter syndrome) is color blind. His 46,XY brother also is color blind. Both parents have normal color vision.The nondisjunction occured in mother during meiosis II that gave rise to the young man with Klinefelter syndrome.
Etiology:
Meiotic Non-disjunction of the chromosome pairs during the First or second division of gametogenesis. Because of the extra chromosome, individuals with the condition are usually referred to as 47XXY. As in the above mentioned scenario, meiotic nondisjunction during meiosis II in the mother resulting in the failure of the sister chromatids to separate during meiosis II thus resulting in too many chromosomes.
