Jet001 [13]4 years ago
8 0

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

The term ____________________ means the lack of muscle coordination during voluntary movement.
tia_tia [17]

The term <u>Ataxia</u> means the lack of muscle coordination during voluntary movement.

  • Poor muscle control that results in awkward voluntary movements is known as ataxia.
  • It might make it difficult to move your eyes, speak, or walk steadily. It might also make it hard to coordinate your hands.
  • Ataxia is typically caused by injury to the cerebellum, which regulates muscular coordination, or its connections.
  • Ataxia is typically brought on by damage to the cerebellum, a region of the brain, although it can also be brought on by injury to the spinal cord or other nerves.
  • The spinal cord, which extends the length of the spine and connects the brain to every other part of the body, is a lengthy bundle of nerves.
