How can a human with 47 chromosomes be produced?
This occurs due to nondisjunction, in which one or more homologous pairs of chromosomes do not separate during anaphase I, or sister chromatids do not separate properly during anaphase II of meiosis. The resulting daughter cells (gametes) will have either 22 or 24 chromosomes. If the gamete with 22 chromosomes unites with a normal gamete with 23 chromosomes, the offspring will have 45 chromosomes (23 + 22). If the gamete with 24 chromosomes unites with a normal gamete, the offspring will have 47 chromosomes (23 + 24). These are usually lethal conditions.
Is genetic diversity due entirely to inherited genes on the sex chromosomes?
No, because genetic diversity has nothing to do with the sex chromosomes but is due to crossing-over of chromosomes independent assortment of chromosomes, and segregation of chromosomes
Is cleft lip due to a lack if chromosomes or extra chromosomes?
No , it is caused by a single gene mutation .
How do the chromosomes become different from eachotther in meiosis?
The chromosomes become different from each other due to crossing over which occurs during prophase I.
What is the name given to body cells due to the number of chromosomes?
Diploid Cells
What is the conclusion of donkey and horse?
When a donkey and a horse breed, the offspring will be called a Mule. Due to the uneven number of chromosomes the offspring will be sterile.
Can a liger produce a offspring?
Actually the liger cannot reproduce to give birth to more ligers. Females can easily breed with male tigers and lions, but all males fail to ever reach sexual maturity and therfore this man-made species would never survive in the wild.
What is Porduced when individuals of different species interbreed and produce offspring?
If the two species are even able to produce offspring, then the offspring would be a hybrid. For example, a donkey and a horse breed to make a mule. Due to the definition of "species," the offspring would either be infertile, inviable or both.
Why can't a mule reproduce?
Mules are hybrid offspring of a male donkey (Jack) and a female horse (mare) Mules have 63 chromosomes, this odd number causes the vast majority to be born sterile. however it should be noted that female mules can reproduce, but this is very uncommon.
Who is stronger a liger or tiger?
a Liger is stronger due to its size, weight, and overall life form.
Can a biological species produce infertile offspring?
Yes donkeys are not fertile due to hybrid breakdown.
Who will win liger vs jaguar?
The cunning liger is proven to be stronger due to interspecies breeding programs.
Why do horses and donkeys remain isolated genetically?
This is due to the different chromosome numbers of the two species, horses have 64 chromosomes as the donkey only has 62 chromosomes. This will leave the offspring to have 63 chromosomes, allowing the pairs to not match correctly and creating successful embryos.
Why is the liger important?
The liger has no importance to the environment. Ligers are not a naturally occurring hybrid animal, only being bred in captivity. If a liger would escape into the wild, it would have little impact due to a lack of survival skills, due to being bred in captivity, and could not breed, due to sterility.

Meiosis is necessary to produce?
Meiosis is a special type of cell division. It is important to reproduce due to the sets of chromosomes in the cell.
What is the off spring of a male horse and female mule be?
There would be no offspring from this cross, because mules are sterile and unable to reproduce due to having an odd number of chromosomes (63).
