Explanation:
A human zygote is diploid (2n = 46), formed by the fusion of a haploid sperm (23) and a haploid ovum (23). It contains 22 pairs of autosomes and one pair of sex chromosomes (XX or XY). Mitotic division then produces all somatic cells. Gametes are haploid (23).

Explanation:
Hemophilia A and B are X-linked recessive, affecting mostly males. Down syndrome is trisomy 21, Turner is XO, Klinefelter is XXY.

Explanation:
In 1944, Oswald Avery, Colin MacLeod, and Maclyn McCarty conducted a landmark experiment building on Griffith's transformation experiment. They purified various macromolecules (DNA, RNA, proteins, lipids) from the virulent S strain of Streptococcus pneumoniae and tested which one could transform the non-virulent R strain into the virulent form. They found that only DNA could cause transformation, and this activity was destroyed by DNase but not by RNase or proteases. This provided the first strong, direct evidence that DNA, not protein, is the genetic material.
