Summary Introduction
To describe:
The difference between sexual and asexual reproduction.
Introduction:
The reproduction can be defined as the process of producing identical offspring. The reproduction can be either sexual or asexual. The sexual mode of reproduction involves two individuals (male and female) and asexual reproduction involves a single individual.
Expert Solution & Answer

Explanation of Solution
The key differences between asexual and sexual reproduction is given below:
Asexual | Sexual |
It occurs in simpler and primitive organisms. | It occurs in complex organisms. |
It is uniparental. | It is generally bi-parental. |
No gametes are formed occurs. Cells are never haploid. | The haploid gametes are required. |
As gametes are not present, gametogenesis is also not required. | The gametogenesis is required to produce haploid cells. |
Fertilization/ fusion of the gametes is absent. | Fertilization/ fusion of the gametes is present. |
Occurs by mitotic cell division. | Involves meiotic cell division. |
The daughter organisms are genetically identical to parent (clones). | The daughter organisms are not genetically identical to parent. |
The multiplication occurs rapidly. | The multiplication cannot occur rapidly. As gamete formation and fusion takes time. |
No genetic variation is found, hence, no evolution. | The |
Conclusion
The asexual reproduction is uniparental mode of reproduction, in which organism are produced by mitotic division and are genetically identical to the parents.
The sexual mode of reproduction requires two parents of opposite sex to produce the genetically different offspring.

According to a recent study, 1 out of 50,000 people will be diagnosed with
cystic fibrosis. Cystic fibrosis can be caused by a mutant form of the CFTR gene
(dominant gene symbol is F and mutant is f).
A. Using the rate of incidence above, what is the frequency of carriers of the
cystic fibrosis allele for CFTR in the US? (3 pts)
B. In a clinical study, 400 people from the population mentioned in (A.) were
genotyped for BRCA1 Listed below are the results. Are these results in Hardy-

Case Study—Ella
Ella has a family history of diabetes. She wants to follow a healthful eating pattern that can lower her risk for developing this condition. Her dietitian recommends a goal of 450 to 600 kcal per meal and advises Ella to follow the Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates and the Dietary Guidelines for Americans 2015-2020, which recommend limiting added sugar. She also recommends that Ella choose whole grains rather than processed grains. Ella decides to pack a lunch to take to work every day. This morning she’s making a sandwich for her lunch.
