Answer:
See explanation below
Explanation:
<em>Non-disjunction occur as a result of lack of separation of homologous chromosomes during meiosis. </em>
As a result, the gametes (the daughter cells formed) produced end up having extra or lesser chromosomes as compared to a normal gamete.
When a gamete with extra chromosome fertilizes a normal gamete, the resulting offspring will have an extra chromosome (trisomy condition).
On the other hand, when a gamete with one less chromosome than normal fertilizes a normal gamete, the resulting offspring will have one less chromosome than normal offspring (monosomy condition).
Assuming a chromosome with Aa gene undergoes non disjunction during meiosis, the resulting gametes either contain both A and a chromosome or contain no chromosome at all.
If Aa gamete is fertilized by a normal haploid sperm (a), the resulting zygote will have the genotype Aaa.
If a gamete with no chromosome at all fertilizes a normal haploid sperm, the resulting offspring will have the genotype a.
Answer:
Approximately it will consume 55% of the total time in the interphase i.e. 800 minutes.
Explanation:
The time required in different phases are as follows:
It takes 800 minutes for interphase
It takes 400 minutes for prophase
It takes 120 minutes for metaphase
It takes 80 minutes for anaphase
It takes 40 minutes for telophase
Total -- 24 hours
From this it can be concluded that around 55% of the time spent in the interphase, whereas only 28% in the prophase, 8% time for metaphase, 6% Anaphase and 3% Telophase. This is all happens in the onion cell but in case of the human cell, prophase it takes about 15 min, in prometaphase it takes 15 mins, metaphase takes in about 20 min, Anaphase takes minimum of 3 min and telophase is about and cytokineses are about less then 10 mins.
