Nadya [2.5K]

In what stage of the cell cycle are the daughter cell produced
marshall27 [118]
The big idea to remember is that mitosis is the simple duplication of a cell and all of its parts. It duplicates its DNA and the two new cells (daughter cells) have the same pieces and genetic code. Two identical copies come from one original. Start with one; get two that are the same. You get the idea.
So it is the very last stage!

Jet001 [13]

Answer: The following is a <u>postzygotic isolating barrier </u>:

  • The hybrid offspring of two species of crocodiles can produce normal gametes but cannot obtain a mate.  

Explanation:

<em><u>Reproductive isolation </u></em>occurs when <em>barriers prevent</em> two populations from interbreeding , <u>keeping their gene pools separate.</u>

We can find the Prezygotic isolation that occurs<u> before fertilization </u>can happen.

And the Postzygotic insolation barriers are the reproductive insulation processes that<u> act after the mating</u>. They are all that concern the viability of the individuals produced.

Prezygotic isolation barriers can be temporal, behavioural, geographic , ecological or mechanical; whereas postzygotic isolation barriers include the inviability, infertility or breakdown of hybrid organisms
