Question

Apple trees reproduce naturally by sexual reproduction. How does this explain why there are many types of Apple's? Be sure to mention meiosis and chromosomes in your answer

Answer 1

Answer: The four cells that are produced by meiosis has only one of each chromosome. One of these four cells from one parent combines with another from the other parent to produce the offspring. An offspring gets half its chromosomes from each parent. But the exact combination of chromosomes it gets from each parent is random. So, each offspring ends up with a unique set of genes different from its parents and other offspring.

Answer 2

Sexual reproduction can be described as the method of reproduction in which the offsprings produced will have half the chromosomes as compared to the parent cell. The other half of the chromosomes to make a complete set would arise from the other parent. In this way, the offspring produced will carry half of the chromosomes from the female parent and half from the male parent.

Crossing over and independent assortment are two phenomenons of meiosis due to which genetic diversity occurs and the offsprings born are not exactly similar to the parent cell.
