In 1859, a small colony of 24 rabbits was brought to Australia. By 1928 it was estimated that there were 500 million rabbits in
Tpy6a [65]

The rabbits had no natural predators  in Australia.

Explanation:

  • 'The rabbits were affected by many limiting factors.' This could not be a possibility because the limiting factors have a negative impact on growth rate of population. The limiting factors hinder the growth of population so if there were too many limiting factors affecting the rabbit, then the growth in population was not possible.
  • The rabbits reproduced by asexual reproduction. Rabbits are mammals and it is a known fact that they reproduce sexually. Thus this option is not possible.
  • The rabbits were unable to adapt to the environment If the rabbits were not adapted to the environment then they must not have survived efficiently in Australia. Hence, this is not a possibility.
  • Thus, the only possibility that remains is that , The rabbits had no natural predators in Australia' Otherwise, the predators would have preyed upon the Rabbits and there population must not have increased in this rate.

Which of the following is NOT TRUE about Y-linked disorders?
Usimov [2.4K]

Answer:

<em>The statement which is not true is C) They can affect males or females</em>

Explanation:

All the chromosomes in a person are known to be autosomal chromosomes except for the sex chromosomes. The sex chromosomes are of two types: Chromosome X and chromosome Y.

Both the sex chromosomes are X in females. Males have one X chromosome and one Y chromosome. The Y chromosome is shorter than the X chromosome. The Y chromosomes occur only in males. Hence, Y- linked disorders will affect only males. These disorders will never occur in females.
