Answer:In many ways, meiosis is a lot like mitosis. The cell goes through similar stages and uses similar strategies to organize and separate chromosomes. In meiosis, however, the cell has a more complex task. It still needs to separate sister chromatids (the two halves of a duplicated chromosome), as in mitosis. But it must also separate homologous chromosomes, the similar but nonidentical chromosome pairs an organism receives from its two parents.
Explanation:Mitosis(Opens in a new window)(Opens in a new window) is used for almost all of your body’s cell division needs. It adds new cells during development and replaces old and worn-out cells throughout your life. The goal of mitosis is to produce daughter cells that are genetically identical to their mothers, with not a single chromosome more or less.
Meiosis, on the other hand, is used for just one purpose in the human body: the production of gametes—sex cells, or sperm and eggs. Its goal is to make daughter cells with exactly half as many chromosomes as the starting cell.
To put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes. In humans, the haploid cells made in meiosis are sperm and eggs. When a sperm and an egg join in fertilization, the two haploid sets of chromosomes form a complete diploid set: a new genome.

Answer:
The correct option is <em>lower.</em>
Explanation:
Schizophrenia can be described as an inherited disease and it is a type of mental illness. As Armend has an identical twin brother with diagnosis of schizophrenia hence, he will have more chances than Robert whose fraternal twin sister has schizophrenia.
As fraternal twins develop from two different eggs hence, the chances in them having the same disease will be lower. Identical twins develop from the same egg, hence they will have more chances of having the same inherited disease.
