How does the number of chromosomes at the end of meiosis compare to the number at the beginning?
It's homicide.
What process takes meiosis this reduced set number and returns it to match the original set number of the parent cell?
Fertilization of the egg by the sperm. The resulting cell is a zygote, which contains the same number of chromosomes as a normal body cell for that species. For example, in humans, sperm cells have 1 set of 23 chromosomes, as do egg cells. So when they unite in fertilization, the zygote will have 2 sets of 23 chromosomes, for a total of 46.
How did meiosis explain Mendel's results?
Mendel's laws and meiosis provide the foundation for heredity.
What major events occur in telophase?
Telophase occur in both mitosis and meiosis. During telophase nuclear membrane and nuclei reforms and in meiosis it further goes for meiosis 2 which is same as mitosis
Why is prophase of meiosis sub-headed with a roman numeral 1?
The Roman numeral I is used to sub-head prophase of meiosis to indicate that it is the first stage of meiosis. Meiosis is a two-step cell division process that consists of meiosis I and meiosis II. By using Roman numerals, the sub-headings help to clearly distinguish between the two stages and show the sequential order in which they occur.
What is a failure of homologous chromosomes to separate in meiosis?
Nondisjunction
How do chromosomes separate?
meiosis
When do homologous chromosomes separate into the daughter cells?
They are separated in Anaphase I of Meiosis I.
A human cell may have more or less than 46 chromosomes as a result of nondisjunction a process in what?
chromosomes fail to separate during cell division
What is a genetic condition that can result when chromosomes don't separate correctly during meiosis?
Trisomy 21 (Down's syndrome), Turner's syndrome (XO), and Klinefelter's syndrome (XXY) are a few examples of genetic disorders that can result when chromosomes don't separate correctly during meiosis.
If nondisjunction occurs during meiosis?
It is the failure of chromosome pairs to separate properly during cell division.
What processes separate eukaryotic chromosomes?
Mitosis and Meiosis
What will separate in the first division in meiosis one?
chromosomes
Which is the failure to segregate during meiosis?
Failure of the chromatids to separate during anaphase onr or two of meiosis
What division of meiosis splits chromosomes?
In anaphase I of meiosis, the homologous pairs of chromosomes separate. Due to DNA replication and crossing over during prophase I, these chromosomes consist of a pair of non-identical sister chromatids. During anaphase II of meiosis, the sister chromatids separate into individual chromosomes.
Which process occurs when chromosomes do no separate during meiosis?
nondijunction
When chromosomes separate what is the process called?
This process is called meiosis.
