Title: How does the chromosome number of the parent cell compare to that of the 2 daughter cells? Post by: rjandmj82 on Sep 5, 2012 and If the parent cell has a chromosome number of 2n=6, what will be the chromosome number of the daughter cells?
Title: How does the chromosome number of the parent cell compare to that of the 2 daughter cells? Post by: lexitrae on Sep 5, 2012 A parent cell, through mitosis, will create daughter cells with the same number of chromosomes as it has (diploid).
Through meiosis (making of gametes) the parent cell will create cells that are haploid, so have half the number of chromosomes of the parent. These cells will have only one of the chromosomes from each pair. Title: How does the chromosome number of the parent cell compare to that of the 2 daughter cells? Post by: rjt6250 on Sep 5, 2012 In Mitosis the cell replicates it self identically so if
original cell 2n=6 daughter cell 2n=6 as they are identical, check out a good explanation here. http://medical-dictionary.thefreedictionary.com/_/viewer.aspx?path=dorland&name=mitosis.jpg More info: Summary of chromosome characteristics * Diploid set for humans; 2n = 46 * Autosomes; homologous chromosomes, one from each parent (humans = 22 sets of 2) * Sex chromosomes (humans have 1 set of 2) 1. Female-sex chromosomes are homologous (XX) 2. Male-sex chromosomes are non-homologous (XY) * Haploid (n)-- one set chromosomes * Diploid (2n)-- two sets chromosomes * Most plant and animal adults are diploid (2n) * Eggs and sperm are haploid (n) |
