Diploid chromosome number in standard laboratory mice (genus Mus) is 40: 19 autosomes and the X and Y sex chromosomes. Whereas the autosomes and the X Chromosome are telocentric (centromere at one end of the chromosome), the Y chromosome is acrocentric
gm foods are made by scientists in a laboratory by mixing genes and chromosomes. hope this was useful :)
In the laboratory, chromosomes can be separated according to length by the electric field of a gel electrophoresis apparatus. The separation of a chromosome into individual units during cell division (mitosis or meiosis) is caused by microtubules which attach the centromere to opposite end of the cell, pulling the two chromatids apart as the cell divides.
Multiploid refers to an organism or cell that contains multiple sets of chromosomes (more than the usual diploid number). This can occur naturally in some plants and animals or can be induced in the laboratory for research purposes. Multiploid organisms may exhibit different characteristics compared to their diploid counterparts.
Observation, Fossil evidence, Molecular Evidence (Comparing DNA and proteins) etc.Human chromosome 2 is widely accepted to be a result of an end-to-end fusion of two ancestral chromosomes.EVIDENCE:The correspondence of chromosome 2 to two ape chromosomes. The closest human relative, the chimpanzee, has near-identical DNA sequences to human chromosome 2, but they are found in two separate chromosomes. The same is true of the more distant gorilla and orangutan.The presence of a vestigial centromere. Normally a chromosome has just one centromere, but in chromosome 2 there are remnants of a second centromere.The presence of vestigial telomeres. These are normally found only at the ends of a chromosome, but in chromosome 2 there are additional telomere sequences in the middle.Chromosome 2 presents very strong evidence in favour of the common descent of humans and other apes. According to researcher J. W. IJdo, "We conclude that the locus cloned in cosmids c8.1 and c29B is the relic of an ancient telomere-telomere fusion and marks the point at which two ancestral ape chromosomes fused to give rise to human chromosome 2."That's just one of thousands!
A Regular field mouse has 46 chromosomes in it's kidney cell, but also in every cell in it's body except its reproductive cells which contain half of that amount.
Karyotyping is a laboratory technique used to visualize an individual's chromosomes. An example of karyotyping is when a karyotype is created from a blood sample to determine if a person has a chromosomal abnormality, such as Down syndrome, by analyzing the size, number, and shape of their chromosomes.
