Place the events in the correct order:
Alecsey [184]

Answer:

1. Chromatin condense into chromosomes.

4. Homologous chromosomes pair up (formation of tetrads).

5. Homologous chromosomes separate and move to poles.

2. Sister chromatids separate.

3. Chromosomes unravel in to chromatin.

Explanation:

This question portrays the process of meiosis in a cell. The ordered sequence of events in the options are:

1. Chromatin condense into chromosomes - This process occurs in the Prophase stage. Prior to the cell division, the nuclear material is found as Chromatin material. This Chromatin material then undergoes condensation to form visible chromosomes.

4. Homologous chromosomes pair up (formation of tetrads) - This process also occurs during the Prophase stage of meiosis I. In this stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) are paired up side by side to form a structure known as TETRAD or BIVALENT.

5. Homologous chromosomes separate and move to poles - This process characterizes the Anaphase stage of meiosis I. Homologous chromosomes are pulled apart to opposite poles of the cell by spindle microtubules.

2. Sister chromatids separate - After meiosis I, meiosis II involving sister chromatids instead of homologous chromosomes follows. In the Anaphase stage of meiosis II specifically, sister chromatids are pulled apart towards opposite poles of the cell.

3. Chromosomes unravel in to chromatin - After the whole division process i.e. karyokinesis (division of the nuclear material), the chromosomes begin to unravel to form the CHROMATIN threads once again. This process occurs in the Telophase stage of meiosis.

Does it matter what order you put the alleles in? Like Bb and bB?
BabaBlast [244]
• It is important. If we write 'bB' , it would be wrong.

◘ First, the dominant genes are written (like B) . This is a must. This is a rule.

◘Recessive genes (like b)  are always written after from the dominant gene. 


=> Namely, 'Bb' should be. 


This is the right shape :)
