    Homologous chromosomes are like the chromosomes an individual inherits from their parents. Like you receive an X from your mother and a Y from your father if you are a boy. The X and Y are homologous chromosomes because they code genes for similar traits though they code for different traits. Of your 46 chromosomes, they make 23 pairs--each of those pairs are homologs or homologous chromosomes. Sister chromatids are the chromosomes when a cell undergoes DNA replication. A chromosome will replicate and one sister chromatid will go to each daughter cell, resulting from the division. The DNA in sister chromatids are identical, assuming no crossing over and synapsis occurs. Learn more information on X Chromosomes Male or Female http://goo.gl/Mxn5m0
