Because the species of finches on the Galápagos island have various appearances but still mate with other finches and produce fertile offspring making it is difficult for scientists to distinguish between two groups of individuals as separate species.
<h3>What is the island of Galápagos?</h3>
The Pacific Ocean island of Galápagos is located to the west of Ecuador. It is a volcanic island known for its diverse and endemic types of living things.
<h3>Why is it difficult to find new species in Finches?</h3>
Charles Darwin spent several years studying the many species of finches on the Galápagos island. He saw a great deal of variation in these finches, which supports the hypothesis of natural selection.
However. it is challenging for scientists to discern between two separate species because the species of finches on the Galápagos island have a variety of features that are different but still mate with other finches and produce fertile offspring.

Ans.
When a yeast cell enters into meiotic cell division, the resulting daughter cells would contain half of the DNA as present in the parent yeast cell. This is because, meiosis results in formation of four daughter cells from a single parent cell and each cell has half of the amount of genetic material as present in parent cell. During meiosis, if a parent cell has 2n DNA, it would first doubles its DNA content (4n), then divides it equally to four daughter cells and thus, each cell contains half of DNA of parent (n).
Hence, the DNA content will become half when a yeast cell shows meiosis.
I say it's in both because every cell has a Nucleus.
