1. Describe how chromosomes determine the sex of a child. 2. Describe how x-linked traits are inherited. In which type of nondisjunction could the two copies of a chromosome in a gamete be heterozygous? Explain. What is non...
errors in the replication process are detected, cells then enter the last stage of the cell cycle; mitosis, or M phase-the point at which dupli- cated chromosomes are neatly segregated into two daughter cells. At its simplest level, the cell cycle is con- trolled by periodic fluctuations ...
1. Genetic analysis in cytogenetics became possible to identify human chromosomes and to promote future techniques [8]; 2. Fluorescence in situ hybridization (FISH) identifies specific nucleic acid sequences from interphase nuclei or applied on metaphase chromosomes of [9]; 3. Comparative genomic ...
Historically, polyploid types were distinguished by their chromosome pairing behavior observed under the microscope during metaphase I of meiosis [91]. Since autopolyploids are formed by genome doubling within the same species, by consequence autopolyploids originate with an identical set of chromosomes....
chromosomes next to an interphase nucleus are acquired and CENP-A signals are quantitated using ImageJ software (http://rsb.info.nih.gov/ij/). The average Integrated Density (ID = average pixel intensity × area) is first calculated from the IDs of individual centromeres within each ...
