Final answer:
Without meiosis in gamete formation, the chromosome number would double with each generation, likely leading to the production of non-viable or genetically compromised offspring.
Step-by-step explanation:
If meiosis did not occur during the formation of gametes, the resulting offspring from sexual reproduction would exhibit a doubling of chromosome number with each generation. Specifically, gametes would be diploid instead of haploid, leading to zygotes that have twice the number of chromosomes as their parents. Since the normal process involves gametes being haploid (containing a single set of chromosomes), fertilization combines these sets to maintain a consistent chromosome number across generations. This hypothetical scenario, where meiosis does not occur, results in non-viable or severely genetically compromised offspring due to having an incorrect number of chromosomes.
