In an organism with a diploid number of 16, how many chromatids are present in each of the following phases:       Mitotic metaphase Meiotic metaphase I Meiotic metaphase II

The process of crossing-over occurs during   Prophase I of meiosis   Prophase II of meiosis   Metaphase I of meiosis   Anaphase I of meiosis   The process of meiosis involves::   one DNA replication and one cell division   two DNA replications and two cell divisions   one DNA replication and two cell divisions   two DNA replications and one cell division   Sporic meiosis, where both the haploid and diploid stages of the life cycle are multicellular, is characteristic of   animals   bacteria   fungi   plants

An individual is heterozygous for a reciprocal translocation, with the following chromosomes: A • B C D E F A • B C V W X R ST • U D E F R ST • U V W X Q. Draw a picture of these chromosomes pairing in prophase I of meiosis.

The mosquito, Aedes aegypti, has 3 bivalents (homologous pairs) formed at Meiosis I. How many chromosomes and chromatin strands are present in each of the following stages:

A diploid (2n) trihybrid individual with the genotype EeFfGg can make eight genetically different gametes.  Loci E/e and F/f are on chromosome 1 and locus G/g is on chromosome 2. Explain how a gamete containing the alleles e, f and g may be produced by meiosis. Refer specifically to meiotic events occurring during Prophase I, Metaphase I, Anaphase I and Anaphase II. (NB: remember to refer to the organism above).
