Mutations in genes that affect meiosis have been identified in many different model organisms. Most of these mutations result in aneuploidy of more than a single chromosome and are nearly sterile. Explain why this is the case.

Concept explainers

Oogenesis

The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.

Cell Division

Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:

Provide two reasons why meiosis leads to genetic variation in diploid organisms.
Assume that a meiotic-nondisjunction event causes trisomy 8 in a newborn. If two of the three copies of chromosome 8 are absolutely identical, at what point during meiosis did the nondisjunction event take place?
The majority of nondisjunction events leading to Down syndrome are maternal in origin. Based on the duration of meiosis in females, speculate on the possible reasons for females contributing aneuploid gametes more frequently than males do.
It is possible that an alternative mechanism for generating germ cells could have evolved. Consider meiosis in a germ cell precursor (a cell that is diploid but will go on to make gametes). If the S phase were skipped, which meiotic division (meiosis I or meiosis II) would no longer be required?
We are following the progress of human chromosome 1 during meiosis. At the end of prophase I, how many chromosomes, chromatids, and centromeres are present to ensure that chromosome 1 faithfully traverses meiosis?
In mice, the Sry gene is located on the Y chromosome very close to one of the pseudoautosomal regions that pairs with the X chromosome during male meiosis. Given this information, propose a model to explain the generation of unusual males who have two X chromosomes (with an Sry-containing piece of the Y chromosome attached to one X chromosome).
The repeat expansion appears to occur during meiosis but not mitosis. Why mightthis be true?
During meiosis, cells undergo two rounds of nuclear and cell division, but only one round of DNA synthesis. Describe the main differences between anaphase of mitosis and anaphase I in meiosis. Why are these differences important for meiosis to occur correctly?
Genes A and B are on different chromosomes. An individual has the genotype: AaBb You sequence two gametes produced by this individual and find one gamete has the genotype AB, and one has the genotype Ab. How can this one individual (genotype AaBb) produce two gametes with different genotypes (AB or Ab)? Your answer should describe a specific process which occurs during meiosis. At what stage of meiosis does this process occur?
Why do you think that humans with trisomy chromosome 13, 18,or 21 can survive but other trisomies are lethal? Even though Xchromosomes are large, aneuploidy of this chromosome is alsotolerated. Explain why.
Meiotic nondisjunction is much more likely than mitotic nondisjunction.Based on this observation, would you conclude that meioticnondisjunction is usually due to nondisjunction during meiosisI or meiosis II? Explain your reasoning?
A sperm cell from the fruit fly Drosophila melanogaster contains four chromosomes. How many chromosomes would be present in a spermatogonial cell about to enter meiosis? How many chromatids would be present in a spermatogo- nial cell at metaphase I of meiosis? How many would be present at metaphase II?
