Define Phenotype 9. Define Mitosis 10. Define Meiosis

Answer 1

5. ANS: Epigenesis: This phenomenon can elaborate about the fundamental embryo development from the undifferentiated structure. It is a step wise process. According to this concept the genetic information can be modified and translate into the substance and the behavior of an organism.

7. ANS: True.

Explanation: Humans do not all have the exact same genes. No two humans are genetically identical.

Ex: Males have a Y chromosome, and females do not.

9. ANS: Mitosis: The mitosis main goal is to produce an identical new cell, which is similar to the parent cell. It this cell division one cell from the the mother can be subdivided and produce two new daughter cells and that are genetically identical to itself.

Mitosis consists of four basic phases:

Prophase

Metaphase

Anaphase

Telophase

Rounds of Cell Division 1

Number of Cells Produced 2

10. ANS: Meiosis

Meiosis is the process through which gametes are produced in each and every organism. Meiotic division is said to be a reduction division whereby the number of chromosomes would be reduced exactly to half of its number. In humans the number of chromosomes is 46 and after meiotic division the gamete formed would have only 23 chromosomes.

In meiosis during prophase crossing-over happens between the sister chromatids when they are aligned along the equatorial plane. This process of crossing-over is what makes each each gamete a unique one and when it fuses with another unique egg, it forms an individual that is unique from the genetic pattern of both father and mother. This is the reason why meiotic division is highly important in sexual reproudction and gamete formation.
