Question 1

If nondisjunction occurs in meiosis I of a mother, what proportion of her gametes could have been fertilized by a normal sperm to produce a child with Turner syndrome?
◦ 0
◦ 1/4
◦ 1/2
◦ 3/4
◦ 1

Question 2

In an allopolyploid organism, what is true regarding the fertility of interspecies hybrids?
◦ Interspecies hybrids are fertile due to nonhomology of chromosomes.
◦ Chromosome doubling by nondisjunction in gametocytes can lead to homologous chromosome pairing, disjunction, and fertile hybrids.
◦ Interspecies hybrids will be fertile so long as there is an odd number of chromosomes in the offspring.
◦ Mitotic nondisjunction results in haploid cells.
◦ Meiotic nondisjunction produces three haploid gametes and one diploid gamete.
