Meiosis is a type of cell division which results in four daughter cells containing half the number of chromosomes of the parent cell. In the human life cycle, meiosis immediately precedes fertilization

1.Independent Assortment
2.Crossing Over(Chiasmata)
3.Random Fertilisation

Meiosis is when a cell divides in half without duplicating its DNA, producing two cells with half the normal amount of DNA.

What changes in the chromosomes occur during meiosis?
waht changes in the chromosomes occur during meiosis
How do independent assortment crossing over and random fertilization affect the rate of evolution?
They will determine how the fertilization will occur. These can allow for some interesting changes to occur with the different plants.
Which does not occur during meiosis?
two diploid daughter cells occur
During which phase of meiosis does crossover occur?
prophase I
During which process does crossing-over occur?
crossing over occurs in meiosis I, specifically during prophase
How meiosis help in generating variations?
Meiosis generates variations due to activities like independent assortment of chromosomes, crossing over and random fertilization that occur during the process. Meiosis occurs during sexual reproduction.
If a child is born with down syndrome when did the mutation occur?
During meiosis
What changes in the chromosomes occur during meiosis?
waht changes in the chromosomes occur during meiosis
What type of division occur to produce an embryo plant from the diploid zygote formed after fertilization?
meiosis
When a child has Trisomy when does the mutation occur?
during meiosis
How many times does meiosis occur in a human?
Remember that meiosis occurs during the production and maturation of gametes so it occurs very often! In males, it occurs virtually throughout their whole life and in females, meiosis I completes at every ovulatory cycle until menopause and meiosis II completes with fertilization.
How do independent assortment crossing over and random fertilization affect the rate of evolution?
They will determine how the fertilization will occur. These can allow for some interesting changes to occur with the different plants.
Explain how meiosis creates genetic diversity in populations.-?
Meiosis creates genetic diversity due to the processes that occur during meiosis. Such as crossing over which creates new gene combinations due homlogous chromosomes swapping or exchanging DNA segments. Independent assortment is also during meiosis and allows the random assortment of homologous chromosomes during metaphase 1.
When does replication occur during meiosis?
Interphase
Which does not occur during meiosis?
two diploid daughter cells occur
During which phase of meiosis does crossover occur?
prophase I
Where do you expect genetic differences between cells to arise from mitosis or from meiosis?
That is a good question. In mitosis, you don't get regular genetic variation but chance mutations can occur. In meiosis with fertilization, you get pairing of DNA from different hosts on a regular basis. I would choose the latter.
