Trisomy 21, or Down syndrome, occurs when there is a normal diploid chromosomal complement but one (extra) chromosome 21. Although fertility is reduced in both sexes, females have higher fertility rates than males. Van Dyke et al. (1995; Down Syndrome Research and Practice 3[2]:65—69) summarize data involving children born of Down syndrome individuals. Assume that children are born to a female with Down syndrome and a normal 46-chromosome male. What proportion of the offspring would be expected to have Down syndrome?
◦ One-third of the offspring would be expected to have Down syndrome.
◦ None of the offspring would be expected to have Down syndrome.
◦ All the children would be expected to have Down syndrome.
◦ Two-thirds of the offspring would be expected to have Down syndrome.
◦ One-half of the offspring would be expected to have Down syndrome.
