Answer:

reduced hybrid fertility

Explanation

The formation of mules  from the cross between female horses (mares) and male donkeys (jacks) is an example of reduced fertility because the mules are sterile and they cannot give birth to babies.

Reason:

Because mule cannot produce sperms. This has to do with his genetics. A mule has 63 chromosomes in total. He gets 32 chromosomes from his mom (that is a horse) and 31 chromosomes from his Dad (that is a donkey). As we know, it is very important for reproduction that chromosomes hould be present in two sets with equal numbers.

To reproduce he needs equal number of chromosomes because we know during meiosis chromosomes segregate and half number goes in daughter cells. But in case of mules he has an extra chromosome due to which he cannot undergo correct meiosis and produce sperms. That is ahy he stays sterile throughout his life. This is called reduced hybrid fertility

Hope it helps!

Complete the sentence: Ecosystem distribution
Step2247 [10]

Answer:

<em>high altitudes will support little vegetation. </em>

Explanation:

Ecosystem distribution is different at different places. Regions at high elevations might usually have low varieties of plants and animals but it cannot be true for every ecosystem located as higher altitudes.

Some communities might be well adapted to live in the cold and hence progress rapidly.
