Answer 2

It seems that your question has a few options. Could you post them too?
We can't help you with questions that provide insufficient information.

Answer 3

Non-disjunction means not separating of the cells correctly. It is chromosomal segregation that will result in an abnormal number of chromosomes. It can occur in Mitosis, meiosis 1 meiosis 2 when the sex cells are involved, It results in homolo (MI) instead of a complete set of chromosomes 46. Easiest answer is that involves chromosomes that fail to separate correctly. If you need more information let me know and I will give you the entire classifications and a description of all 3 non-disjunction areas

Answer 4

It results in homolo (MI) instead of a complete set of chromosomes 46. ??

Answer 5

Was trying to figure out how to combine all 3 options into one easy explanation for understanding,

Answer 6

Would be beneficial if had more information I agree, Would definitely help if it was involved in reproduction or all other cells but reproduction, Thanks Abhisar It would be helpful to narrow down the options

Answer 7

It's ok @jeeppgirl , but i have a doubt on the line u posted. Can u please rectify or explain it ?

Answer 9

Do u mean homologous recombinant by homolo (MI) ?

Answer 10

As @jeeppgirl said, Non-Disjunction will lead to incorrect segregation of chromosomes. It will result into polyploidy i.e more than two sets of chromosomes or monoploidy i.e only 1 set of chromosome in diploids. For example Down'S syndrome. It occurs due to trisomy on chromosome no 21. turner's syndrome is an example of monoploidy in which females have only one X chromosome.

Answer 11

Any cells not related to sex cells i.e skin, blood, are caused by mitosis and homolo (MI)
is not a full set of chromosomes, 1/2 from each Most common occurs in Meiosis 1 which makes this the most clinically significant It causes Aneuploidies' in humans. Homolo(MI) is what I consider from study short for homologous

Answer 12

Yes

Answer 13

:)

Answer 14

We always called it Homolo (MI) since it was missing significant chromosomes

Answer 15

Thank you
