48) People with Down Syndrome have A) three of all the chromosomes, including X and Y_ a diploid set of autosomes, but only one sex chromosome: a haploid set of chromosomes, plus one extra of number 21. D) a diploid set of chromosomes, except only one of number 21. E) a diploid set of chromosomes, plus one extra of number 21. 49) Most sex-linked conditions are caused by A) genes that only males have. inheritance of an extra X chromosome- genes on the X chromosome_ proteins that damage the X chromosome E) genes that only females have:
