Chromosomes come from two parents. They match up so the number must be divisible by two.
A diploid number means there are two of every kind of chromosome. For example, humans have 2 sets of 23 chromosomes for a total of 46. Two times any number results in an even number.
Chromosomes come in pairs, so the number is even.
No, some bacteria and other unicellular organisms have a single chromosome
because every chromosome must have a pair to survive
The answer is 1. The number 2 is the only even prime number
The number 217 is odd. Two even number add up to an even number so there are not two consecutive even number that total 217. Let 2m be any even number, 2k be another one There sum is 2(m+k) which is even.
Chromosome numbers are typically even in normal organisms because chromosomes exist in pairs, with one chromosome inherited from each parent. This diploid state (2n) allows for homologous chromosomes to align and separate properly during meiosis, ensuring accurate gamete formation. An even number of chromosomes facilitates genetic diversity through recombination and maintains genomic stability across generations. Additionally, many organisms have evolved this structure as a means of effectively organizing and regulating their genetic material.
All the autosomes are paired but the sex chromosome of a number of animals are not paired and they reproduce successfully.
No. Not even close.
Yes, In most cases all somatic cells are diploid but in some organisms it is not the case, Gametophytes of plants are always haploid. Bacteria are also haploid. In angiosperms, the endosperm; which is considered somatic; is a tissue consisting triploid cell. Some time its chromosome number varies from 2n to 15n.In some conifers , like Sequoia sempervirens, chromosome number is 6n (Hexaploids).So, even in somatic cells, there is a large variety in chromosome number.

because in a mean for 7 with three numbers the total of the 3 numbers must be 21 and (even number) + (even number) = (even number) 21 is odd Q.E.D
