Answer:
If during meiosis the efficiency to form tetrads is reduced or absent -due to a mutation- this defect would most likely affect the ability to align homologous chromosome at the metaphase plate.
Explanation:
Options for this question are:
<em>a) Breakdown the nuclear membrane
</em>
<em>b) Duplicate centrosomes
</em>
<em>c) Assemble spindle microtubules
</em>
<em>d) Establish spindle poles
</em>
<em>e) Align homologous chromosome at the metaphase plate</em>
During the zigoteno of the prophase I (meiosis) the bivalent chromosomes are formed, product of the pairing of genes. Each of the chromosomes of a pair is constituted by two sister chromatids, resulting in a structure called tetrad, due to the existence of four chromatids.
If in the next phase, metaphase, tetrad (four chromatides) has not formed, alignment in the equator and spindle synthesis is not possible, so the metaphase plate is not formed and the respective chromosomes cannot migrate to cell poles.

Answer:
Yes
Explanation:
All mutations will be passed onto new cells through DNA replication, and all RNA made from that DNA will also have the mutation. If the mutation occurs in sperm or egg cells, those mutations will also be passed on to the organism's offspring.
It would be two i guess because 3 times 2 is 6
Mother. red-green color blindedness is maternally inherited
I believe it's Lower.
Hope this helps!
