User: 1. Autosomes are _______ chromosomes. A. homologous B. abnormal C. haploid D. nonsex

Weegy: Answer: C.nonsex n autosome is any of the numbered chromosomes, as opposed to the sex chromosomes. Humans have 22 pairs of autosomes and one pair of sex chromosomes (the X and Y). Autosomes are numbered roughly in relation to their sizes. [ That is, Chromosome 1 has approximately 2,800 genes, while chromosome 22 has approximately 750 genes. ]

User: 12. Which of the following processes occurs during meiosis and not mitosis? A. Crossing-under B. Crossing-over C. Cytogenesis D. Cytokinesis

Weegy: The answer is A. bec A. Crossing over occurs for gamete formation and it is typical of the diplotene phase of meiosis 1. It is responsible for genetic variation.
