there is no relationship between size of organism and its chromosome number. A smaller organism may have more chromosomes than a larger organism. (b) No, process of reproduction follows a common pattern and is not dependent on the chromosome number.
Can organisms with fewer chromosomes reproduce more easily than organisms with more chromosomes?
(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.
Can organisms with fewer chromosomes?
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.
Does the number of chromosomes affect the complexity of an organism?
The number of chromosomes does not correlate with the apparent complexity of an animal or a plant: in humans, for example, the diploid number is 2n = 46 (that is, 23 pairs), compared with 2n = 78, or 39 pairs, in the dog and 2n = 36 (18) in the common earthworm. There is an equally great range of numbers among plants.
Are extra chromosomes beneficial to organisms?
A condition in which every cell in the body has an extra set of chromosomes is not compatible with life. In some cases, a change in the number of chromosomes occurs only in certain cells. When an individual’s cells differ in their chromosomal makeup, it is known as chromosomal mosaicism .
Do larger organisms have more no of chromosomes?
(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 more number of chromosomes cells Class 10?
(a) There is no relationship between the number of chromosomes and the size or the complexity of the organism. Example: Ophioglossum reticulatum are small ferns that have 630 pairs of chromosomes.
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.
What happens when you have 47 chromosomes?
Humans have 23 pairs of chromosomes. A trisomy is a chromosomal condition characterised by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.
Why do some animals have more chromosomes than others?
Through the course of evolution, some species have generated multiple copies of their chromosomes due to errors in meiosis, when the sex cells or gametes are produced. … Having more than two copies of each chromosome is called polyploidy.
