Detailed explanation-1: -No, sex cells have a half set of chromosomes. 23, one from each pair. That is correct. 23, pairs 1-11 and one selected randomly from the remaining pairs.
Detailed explanation-2: -They cannot have duplicate information of the same gene. Gametes when fuse with the other half i.e. opposite gamete, the zygote which is formed will have two set of chromosomes. This makes the zygote diploid and hence ploidy (Number of chromosomes) are maintained in the next generation.
Detailed explanation-3: -In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.
Detailed explanation-4: -The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
