Hi there!
Australian rabbits are an invasive species. They reproduce quickly and eat crops, especially root vegetables, cabbage, etc.
Because of this, humans are effected because they destroy our food.
Also, there's pressure on the local predators to kill them all, and they can quickly outnumber them.
As much as they may be cute, they damage the ecosystem that way!

The correct term to fill in the blank is "no more". Fraternal twins are no more similar genetically than are other brothers and sisters. They are also known as dizygotic twins since they are formed from 2 different amniotic sacs and placentas which means they are totally developed from two different eggs and being fertilized by different sperm cells. So, they have different characteristics. The genetic code they would have would be the same as any other sibling. So, they are not identical. The other type of twins is called the monozygotic or the idetical twins. This type would have the same genetic codes.
Answer: Crossing-over contributes to genetic diversity or variation.
Crossing-over is when homologous* chromosomes exchange genes. This result in different gene combinations.
