Treatment of cells with the chemical colchicine interferes with microtubule assembly in metaphase and anaphase. What are the resulting mutations? - -Nondisjunction mutations deletion mutation - -a mutation in which one or more pairs of nucleotides are removed from a gene Insertion - -A mutation involving the addition of one or more nucleotide pairs to a gene. An error in DNA replication leads to adding an extra cytosine. This causes the DNA sequence CTCGTT to change to CCTCGTT. Which type of mutation has occurred? - -Insertion mutation What may result if the sister chromatids of one chromosome fail to separate during meiosis II? - - Gametes with one extra or missing chromosome During which phase of meiosis do homologous chromosomes line up at the equator of the cell? - - Metaphase I What does the process of meiosis result in? - -A reduction in the chromosome number Why is crossing-over one of the most important events in meiosis? - -It produces new combinations of alleles on chromosomes. Which mode of inheritance describes a condition that exclusively affects males? - -Y-linked A man with disease X and a woman without disease X have five sons and five daughters.
