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

How many chromosome does a mouse receive from its male parent?
A mouse receives 19 chromosomes from its male parent. A typical mouse has 40 chromosomes, with 19 coming from the male and 19 from the female parent. Additionally, mice have one pair of sex chromosomes, with males having one X and one Y chromosome, while females have two X chromosomes.
When DNA is copied to form chromosomes that have 2 sister chromatids this is called DNA .?
Each chromosome has two arms, labeled p (the shorter of the two) and q (the longer). The p arm is named for "petite" meaning 'small'; the q arm is named q simply because it follows p in the alphabet. (According to the NCBI, "q" refers to the French word "queue".) They can be Metacentric A chromosome is metacentric if its two arms are roughly equal in length. In some cases, a metacentric chromosome is formed by balanced Robertsonian translocation: the fusion of two acrocentric chromosomes to form one metacentric chromosome. Submetacentric If arms' lengths are unequal, the chromosome is said to be submetacentric Acrocentric If the p (short) arm is so short that is hard to observe, but still present, then the chromosome is acrocentric (The "acro-" in acrocentric refers to the Greek word for "peak."). In an acrocentric chromosome the p arm contains genetic material including repeated sequences such as nucleolar organizing regions, and can be translocated without significant harm, as in a balanced Robertsonian translocation. The domestic horse genome includes one metacentric chromosome that is homologous to two acrocentric chromosomes in the conspecific but undomesticated Przewalski's horse. This may reflect either fixation of a balanced Robertsonian translocation in domestic horses or, conversely, fixation of the fission of one metacentric chromosome into two acrocentric chromosomes in Przewalski's horses. A similar situation exists between the human and great ape genomes; in this case, because more species are extant, it is apparent that the evolutionary sequence is a reduction of two acrocentric chromosomes in the great apes to one metacentric chromosome in humans Telocentric A telocentric chromosome's centromere is located at the terminal end of the chromosome. Telomeres may extend from both ends of the chromosome. For example, all mouse chromosomes are telocentric Holocentric With holocentric chromosomes, the entire length of the chromosome acts as the centromere. Examples of this type of centromere can be found scattered throughout the plant and animal kingdoms with the most well known example being in the worm, Caenorhabditis elegans.
What is the 17Th human chromosome?
Acrocentric
What are chromosome types?
They are typed as telocentric acrocentric
How many chromosomes are in a mouse's gamete?
Gametes only have one set of each chromosome pair so that when two gametes come together, the chromosome number in the embryo is correct. There are 19 autosomes and one sex chromosome in the mouse gamete.
A chromosome with sub-terminal centromere is?
acrocentric chromosome
What is an acrocentric?
An acrocentric is a chromosome which has the centomere, the central region, closer to one end than the other, thus having one short arm and one long arm.
Are all of cow chromosomes telocentric?
I thought they were acrocentric (centromere positioned so close to the end of the chromosome that the short arm of the chromosome is not visible) rather than telocentric (centromere located completely at the terminal end of the chromosome).
