Answer:
recombination and independent segregation of chromosomes during meiosis
Explanation:
Recombination and independent segregation of chromosomes represent the two most important meiotic mechanisms by which sisters from the same parents can inherit different gene variants and therefore look very different from each other:
1- Independent assortment (segregation) of chromosomes: during meiosis, homologous chromosomes are randomly distributed in daughter cells (which will give rise to the gametes), and therefore separate independently of each other. It is for that reason that gametes have unique combinations of chromosomes, which increases genetic variation.
2- Recombination, also known as crossing over, refers to the exchange of chromosome segments between non-sister chromatids during meiosis. This mechanism is well-known to produce new gene variants (alleles) in the daughter cells. In consequence, recombination also increases the genetic variation of the resulting gametes that will produce offspring (in this case, different sisters).
If im not mistaking it will be A is the only other one that really makes any sense
You answer would be B because half n half from ur parents
Answer:
hey hii hello we are good friend
Answer:
It would most likely show that at some point Australia in that area had lots of dense forestry in that region as the abundance of forestry would be needed to be turned into coal.
Explanation: During the carboniferous the planet was covered in a large abundance of forestry that would often go into that ground and be compressed by other plant life and occasional flooding of seas and would eventually be turned into coal over millions of years.
