Question

The primary reason for hybrid sterility is:_____.

a) The inability for the hybrid to develop and appropriate courtship pattern
b) The inability for the hybrid to attract a male
c) Hybrids cannot produce viable gametes
d) Hybrids are usually weak, and have difficulty surviving to reproductive maturity

Answer 1

Hybrid sterility is caused by the inability of hybrid organisms to produce viable gametes due to genetic incompatibilities between two different species.

Step-by-step explanation:

The primary reason for hybrid sterility is the inability of hybrids to produce viable gametes. This is due to genetic incompatibilities that arise when two different species mate, resulting in offspring that cannot form normal gametes necessary for reproduction. An example of hybrid sterility is seen in the mule, which is the infertile offspring of a female horse and a male donkey. Furthermore, in the process of polyploidy, the chromosome number may be altered to overcome hybrid sterility, yet this outcome typically requires human intervention, such as in the case of certain ornamental and commercial plants like the banana.

Hybrid sterility occurs when reproductive barriers prevent the hybrid from producing viable gametes, which are necessary for successful reproduction. These barriers can include genetic incompatibilities that interfere with proper development of the offspring, or the offspring may be unable to produce viable gametes themselves. An example of hybrid sterility is the mule, which is the infertile offspring of a female horse and a male donkey.
