What are four types of chromosomal mutations?
Four types of chromosomal mutations are Down syndrome (which is a mutation in which there are three copies of chromosome 21), Kinefelter Syndrome (which is a mutation in which a male has an extra X-chromosome), Turner Syndrome (which is a mutation in which a female is missing an X-chromosome), and Patau Syndrome (which is a mutation in which there are three copies of chromosome 13).
What is a chromosome called when it gets lost during mitosis?
" gets lost "I think you are describing a nondisjuction event where the chromosomes are not properly pulled apart to their proper positions by the mitotic spindle.
Humans who have lost one copy of an autosome are called?
Humans who have lost one copy of an autosome are called heterozygous for that specific chromosome. This condition is known as monosomy for that particular autosome.
The Y chromosome is larger and carries fewer genes than the X chromosome?
No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the Y chromosome.
Is the male x gene dying out?
No, the male X chromosome is not dying out. Though, according to science, the male Y chromosome is shrinking, and in a few billion years, there will be no male humans, but that is only according to science.

What diagram models deletion in which a chromosomes breaks and a piece of DNA is lost?
A deletion mutation is best represented in a karyotype diagram, where a section of a chromosome is missing or deleted. This is shown as a gap or break in the chromosome. Alternatively, a chromosomal ideogram can also illustrate a deletion by displaying a portion of a chromosome missing or shortened.

Humans who have lost one copy of an autosome are called heterozygous for that specific chromosome. This condition is known as monosomy for that particular autosome.
When a chromosome undergoes a delation mutation information is?
Information is lost.
When parts of chromosomes are broken off and lost during mitosis or meiosis the result is an?
when parts of chromosomes are broken off and lost during mitosis the results is a chromosomal mutation
When parts of chromosomes are broken off and lost during mitosis or meiosis the result is?

Describe four types of mutation resulting from the breakage of chromosome?
Deletion: a segment of the chromosome is lost during breakage. Duplication: a segment of the chromosome is copied and inserted back into the chromosome following breakage. Inversion: a segment of the chromosome is reversed and re-inserted following breakage. Translocation: a segment of the chromosome breaks off and joins a different chromosome.
What happens if asegment of DNA is deleted?
It would be as if a part of a chromosome were lost. This is called a deletion. It can cause a gene to be lost or not expressed. Several genetic disorders are caused by this process.
Most serious problem associated with the inversion of genetic material?
Chromosomal defects in offspring. Because no genetic material is lost with inversion of genetic material, individuals often have no obvious physical effects. The major risk with the inversion of genetic material is that offspring of these individuals may have more severe chromosomal abnormalities.
The Y chromosome is larger and carries fewer genes than the X chromosome?
No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the Y chromosome.
If a cell that undergoes meiosis later is four cells with chromosome numbers 17 17 18 and 16 what happened?
one of the sister chromatids in one of the two cells that was produced during the first division of meiosis did not separate during the second division resulting in one cell with an extra chromosome and one with a missing chromosome. This process is known as nondisjunction
