Cell division during mitosis is necessary for replacing damaged or dying cells, as well as repairing damaged or worn-out cells that occur naturally. The main mechanism behind growth is this kind of cell division.
<h3>
What are the consequences if mitosis stopped in the body?</h3>
Without mitosis, there wouldn't be any cell division or growth. The fact that genetic information cannot be passed on is most essential. All cell processes would be significantly impacted.
You might also suffer serious consequences, as your heart would have to beat by itself, among other things. Your bones or your brain wouldn't be immediately impacted, but your blood cells would.
Therefore, Every cell in your body would stop replicating itself if mitosis halted, which would induce a heart attack.

Answer:
The ratio of blue to white offspring in the progeny is 4 blue : 12 white.
Explanation:
<u>Available data:</u>
- The dominant allele K is necessary to synthesize blue flower pigment
- K is inhibited by the dominant allele D
- Plants with the genotype K- D- will not produce pigment (and their flowers will be white)
Cross: testcross for (Kk Dd) plants
Parental) KkDd x kkdd
Gametes) KD kD Kd kd
kd kd kd kd
Punnet square) KD Kd kD kd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
- Whenever D is present, it inhibits the expression of the K gene, so every plant with the dominant D allele will be white. This plants´ genotype is kkD- or K-D-.
- Whenever D is absent and K is present, every plant with genotype K-dd will be blue.
- The recessive form for K and D genes will express white-flowered plants, with genotype ddkk
F1) Progeny genotype: 4/16 KkDd, white-flowered plants
4/16 Kkdd, blue-flowered plants
4/16 kkDd, white-flowered plants
4/16 kkdd, white-flowered plants
The ratio of blue to white offspring in the progeny is 4 blue : 12 white.
Blue-flowered plants: 4 Kkdd
White-flowered plants: 4 KkDd + 4 kkDd + 4 kkdd
