Can each chromosome usually contain multiple genes? yes each chromosome usually contains more than one gene.
True. The sex of offspring is determined by the sex chromosome contributed by the female parent. Females have two X chromosomes, while males have one X and one Y chromosome.
No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the Y chromosome.
As of now, the claim about the chromosome 2 fusion site being debunked has not been conclusively proven false.
A human cell contains 46 cromosome (44 autosome, 2 sex cromosome)
False. In cases of individuals with turner syndrome, Females have only 1 X chromosome to determine sex, where "normally" a female has XX or a male has XY. Now understand that a zygote is a fertilized egg. If you meant gametes, which are egg or sperm cells, True, non-disjunction causes an excess amount of chromosomes in at least one of the four gametes that meiosis produces. I hope that helps.

False. A mutation refers to a change in the DNA sequence of a gene or chromosome, not the specific part of a chromosome that carries information about a trait.
