Homework Answers
Ans:True. Yes humans are able to tolerate extra number of sex chromosomes than extra number of autosomes. They are rarely lethal and is less severe in their effects. Eg: Turner Syndrome. Abnormal autosomes usually leads to death of a fetus even before birth and those that survives have many physical malformations, mental problems and short life span. Eg: Down Syndrome.

Answer Key: Mitosis only, Meiosis Only, Both Mitosis and Meiosis, Neither In , independent assortment of chromosomes occurs. In , daughter cells are identical to the mother cell. In , homologous chromosomes consisting of sister chromatids line up separately along the metaphase plate. In , the synaptonemal complex forms between homologous chromosomes. A haploid cell can replicate by A gametophyte produces eggs and sperm by Cytokinesis generally occurs in

Mitosis and Meiosis. 1. Draw a cell where 2n = 6 in each phase of Mitosis, Meiosis 1, and Meiosis 2. Be sure to clearly indicate what is going on with the 1-nuclear envelope, 2-centrosomes, 3-chromosomes in each of the stages. 2. For a diploid organism where 2n = 16, please indicate the number of chromosomes and chromatids at each of the Mitosis, Meiosis 1, Meiosis 2 stages.

What is a major difference between mitosis and meiosis I in a diploid organism? Only meiosis I results in daughter cells that contain identical genetic information. Sister chromatids separate in mitosis; homologous pairs of chromosomes separate in meiosis I. Sister chromatids separate in mitosis; homologous pairs of chromosomes separate in meiosis II. ODNA replication takes place prior to mitosis, but not before meiosis I.

In Drosophila, nondisjunction during meiosis in the parent can result in flies with abnormal numbers of sex chromosomes. Flies with a single X and no Y are male, and those with XXY are female. Which of the following events could not give rise to a male with a single X in Drosophila? Nondisjunction at meiosis II in the female parent Nondisjunction at meiosis I in the male parent Nondisjunction at meiosis I in the female parent All of these CAN...
