A eukaryotic diploid cell from an organism with the XX-XY sex determination system has two pairs of autosomes and a pair of sex chromosomes, X and Y.
1. A diploid cell from this individual undergoes meiosis. Which of the following is a possible normal combination of chromosomes in one of the gamete cells after the completion of meiosis II (assuming meiosis occurred correctly)?
a) A chromosome with the 'A' allele, one with the 'a' allele, one with the 'B' allele, one with the 'b' allele, and one X.
b) A pair of chromosomes with 'A' alleles, a pair of chromosomes with 'B' alleles, and a pair of Y chromosomes.
c) One chromosome with an 'a' allele, one chromosome with a 'B' allele, and one X.
d) One chromosome with the 'A' allele, one with the 'B' allele, one X, and one Y.
