Trisomy and monosomy can be a product of nondisjunction in _______ .
a. meiosis I
b. meiosis II
c. mitosis
d. Both a and b
e. All of the above
Homework Answers
Answer:d.Both a and b
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division. Monosomy is the lack of one member of a chromosome pair.Trisomy is the triplet instead of the normal chromosome pair. Both are typically the result of nondisjunction during meiosis.

5. Humans with autosomal trisomy sometimes survive past birth, but humans with autosomal monosomy do not, because: a) monosomy reveals recessive lethal alleles whereas trisomy does not b) monosomy disrupts the proper balance of gene products produced from genes on different chromosomes, whereas trisomy does not c) for certain chromosomes, it is possible to “turn off” a third copy to avoid too much gene expression d) this is a trick question because some people with autosomal monosomy survive

Can you guys please fix this for me. my project: Monosomy is the absence of one chromosome from a paired chromosome. For example, Down’s syndrome which has more one chromosome at nubmer21. It makes 47 chromosomes totally. The trisomy reflects the presence of an extra chromosome to the cell. For example, in Turner’s syndrome person has one less X chromosome. Non-disjunction is failure of cell division when chromosomes separation was occurring. If any chromosome get remains during the separation; means...

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...

Zylins are a diploid, 2n = 6, species and a common mutation
found in baby Zylins is trisomy 3 (2n +1). You are
trying to determine if this trisomy is more commonly caused by
nondisjunction events during egg formation or sperm
formation. A Southern blot, labeled with a probe for
RFLPs on chromosome 3, for one of your test families is shown below
