Question

In animals normally which organism has the maximum number of chromosomes?
A) Butterfly
B) Elephant
C) Hermit crab
D) Chimpanzee

Answer 1

Chromosome numbers are termed as the correct number of chromosomes for a species. Chromosome number is the same for a particular kind of species and differs for different species. An increase or decrease that occurs in the particular chromosome number generates abnormalities.

Complete answer:
Humans contain chromosomes that usually pair. The copy of each chromosome is carried on from the female parent and the male parent. Males chromosomes are different than those of female chromosomes which are known as sex chromosomes. If enough and normal amount of copies of chromosomes will not be inherited then it leads to a serious problem.

Now let us find solution from given options:
A) Butterfly : Butterfly contains a large number of chromosomes. The chromosomes number in the butterfly 380. This animal belongs to an insect phylum.
B) Elephant : Elephant belongs to mammals of the animal kingdom. The chromosome number in elephants is diploid set and that is equal to 56 chromosomes.
C) Hermit crab : Hermit crab belongs to molluscs of the animal kingdom. The chromosome number in hermit crab is 254.
D) Chimpanzee : Chimpanzees belong to mammals of the animal kingdom. The chromosome number in chimpanzees is 48.

Hence the correct answer is option ‘A’ i.e, butterfly.

Note: Chromosomes exactly look like the thread-like structure and are mainly present in the nucleus of the cell. A chromosome is generated when the highly tight DNA coil around the protein called histones. Chromosomes are made of the long strands of DNA that contain genetic information in it.
