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!

Kipish [7]

Out of the following given choices;

a.            Valine instead of glutamic acid in the sixth position

b.            Glutamic acid replacing valine in the first position

c.             Extensive amino acid substitutions

d.            Trinucleotide repeats

e.            Frameshift substitutions

The answer is A. this is caused by a mutation in the beta thalassemia genes on one of the 46 human chromosomes (chromosome #11) of the individual. The alpha subunit is normal in people with sickle cell disease. When sickle hemoglobin releases oxygen in the peripheral tissues, the molecules tend to stick together and form long chains or polymers. These rigid polymers distort the cell and cause it to bend out of shape from the normative disc shape.
