Most humans have 23 pairs of chromosomes, 22 of which are the same in both males and females. The 23rd pair differ in that females have two X chromosomes, while males have one X and one Y chromosome.
A chicken has 78 chromosomes.
False. Different species have different numbers of chromosomes. For example, humans have 46 chromosomes (23 pairs), while dogs have 78 chromosomes (39 pairs).
No, different species have different numbers of chromosomes. Humans have 46 chromosomes, dogs have 78 chromosomes, and horses have 64 chromosomes, for example. The number of chromosomes in a species typically remains constant within that species.
No, chromosomes vary from species to species. A species is distinguished by individuals that can mate and have young that are capable of producing offspring. The number of chromosomes two individuals have must be the same for this to be possible.
It all depends on the type of organism on many chromosomes are present in each cell. By regular cell division each new cell will have the same number as the original cell. Some organisms have many more chromosomes than humans do and some have many less chromosomes.
A chicken has 78 chromosomes.
humans have a total of 46 chromosomes(:
A lobster has 100 chromosomes. Humans have 46 chromosomes, the same as a lizard. A dog has 78 chromosomes, and a fly has 12 chromosomes.
False. Different species have different numbers of chromosomes. For example, humans have 46 chromosomes (23 pairs), while dogs have 78 chromosomes (39 pairs).
No, different species have different numbers of chromosomes. Humans have 46 chromosomes, dogs have 78 chromosomes, and horses have 64 chromosomes, for example. The number of chromosomes in a species typically remains constant within that species.
Humans have 46 chromosomes.
Same as humans: in the nucleus of the cell.
Yes, all great apes have 24 chromosomes while humans have 23.
In humans and other mammals, a male has XY sex chromosomes. In birds, a male has XX chromosomes. In amphibians, male chromosomes look the same as female chromosomes.
No, not all sexually-reproducing organisms have the same sex chromosomes as humans. Humans possess a XY sex-determination system, where males have XY chromosomes and females have XX chromosomes. Other organisms can have different systems; for example, birds typically have a ZW system, where males are ZZ and females are ZW, while some reptiles and fish may have varied systems. The diversity in sex chromosomes reflects the evolutionary adaptations of different species.
46 in humans, which is the same as 23 pairs
No, chromosomes vary from species to species. A species is distinguished by individuals that can mate and have young that are capable of producing offspring. The number of chromosomes two individuals have must be the same for this to be possible.
