What if humans could reproduce through mitosis instead of using meiosis? What would children look like if parents reproduced using mitosis? Would there be any pitfalls in a population of humans if mitosis were the primary method for reproduction?
We know that mitosis in equational division. One parent cell undergoes mitosis to form two daughter cells. The daughter cells formed are identical to one another and also to the parent cell. There are no variation in the process of mitosis. Hence, if mitosis was used as the means of formation of gametes and undergoing reproduction, then there would have been no variations among all the individuals present on this planet and the process of evolution would not have taken place. By the word evolution, we mean to say that the organisms are evolving by creation of variation and absence of mitosis would mean absence of variation and absence of evolution.
If meiosis was primarily used for the maintenance and growth of somatic body of an individual, then after every round of cell division, the amount of DNA present in the cell would have reduced to half. This would have led to decrease in the size of cell and therefore decrease in the size of organism with the course of time. This would have been a great problem because the organism would have been left with very less amount of DNA at some point of time as compared to the amount of DNA present initially in organism. This type of process would not have been maintained in reality.

1. What does it mean for an allele to be dominant? (i.e. How do you know that Mendel's yellow seeds were considered dominant?) 2. In humans, apparently, the presence of dimples is a dominant characteristic. If the inheritance pattern of dimples is like that of pea color (i.e. two forms, dimples and no-dimples, one dominant and one recessive), described by Mendel, could non-dimpled parents give birth to a dimpled child? If non-dimpled parents do give birth to dimpled children, what...

How would you define health education and why? Briefly describe the school children in USA population and their Obesity plus poor eating habit both at school and homes of low income parents as the health issue you would address if you were assigned to design and implement a prevention program.

Do education programs for preschool children that follow the Montessori method perform better than other programs? A study compared five-year-old children in Milwaukee, Wisconsin, who had been enrolled in preschool programs from the age of three. All the children in the study applied to the Montessori school. The school district assigned students to Montessori or other preschools by a random lottery. (a) Comparing children whose parents chose a Montessori school with children of other parents would not show whether Montessori...
