there is no relationship between size of organism and its chromosome number. A smaller organism may have more chromosomes than a larger organism.
Do larger organisms have more number of chromosomes cell?
Answer: Explanation: a) No, there is no correlation between size of organism and its chromosome number. Even smaller organisms may have more chromosomes than the larger ones.
Do larger organisms have less chromosomes?
(a) There is no relationship between the number of chromosomes and the size or the complexity of the organism.
Which organism has more chromosomes?
In fact, the world record holder for the most chromosomes is the fern Ophioglossum reticulatum with 1260 chromosomes!
Do large organisms have more cells than small organisms?
No, bigger organisms do not have bigger cells. Although the sizes of different cells might differ ever so slightly, most cells are roughly the same…
Can organism with fewer chromosomes reproduce more easily than organisms with more number of?
(b) Can organism with fewer chlromosomes reproduce more easily than organisms with more number of chromosomes? … (c) Yes, since the major component of chromosome is DNA, if there are more chromosomes in a cell. The quantity of DNA will also be more.
Why and how do organisms vary in their chromosome number?
Chromosome numbers vary significantly in different organisms. … Especially in those organisms with more chromosomes, the ability of homologs to find one another, pair, and remain together during the first meiotic division is critical to avoid chromosome mis-segregation and resulting aneuploidy.
Why do some organisms have less chromosomes?
Fusion: Decreasing chromosome number
Fusion is a common way for animal species to end up with a different number of chromosomes from their ancestors. In fact, fusion is most likely what happened to humans on their way from the common human-chimp ancestor.
What determines how many chromosomes are in an animal?
Each chromosome contains hundreds or thousands of different genes. Chromosomes are found in pairs within the cell. Each cell contains two separate copies of each gene (alleles). While a human has 46 chromosomes (23 pairs), a cat has 38 chromosomes (19 pairs) and a dog has 78 chromosomes (39 pairs).
