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

Answer:
C. Dark Moths had a survival disadvantage in industrial Dorset
Explanation:
Looking at the graph, you can see that the Dark Moth, compared to the Light Moth actually had a survival advantage.
I won't be explaining the why's to this phenomena, considering that the question is based solely on the graph.
Compare the two bars of Dorset. The Light Colored moths are represented by the green graph while the Dark colored moths are represented by the orange bar. The orange bar extends further that the green bar, showing that they recovered better than the other. So this means they were at an advantage and NOT at a disadvantage.
