<h2>
Answer:</h2>
Cells undergoing mitosis just divide once because they are forming two new genetically identical cells where as in meiosis cells require two sets of divisions because they need to make the cell a haploid cell which only has half of the total number of chromosomes.
Answer:
to organize the eras and periods of major events of fossils
Interphase: You could not distinguish any parts of the cell.
Prophase: You could clearly see the chromosomes throughout the cell.
Metaphase: The chromosomes where lines up in the middle of the cell.
Anaphase: You could see the chromosomes were separated to ether side of the cell.
Telophase: The entire cell was separated to each side but was not split into its own cell.
Cytokinesis: In this step the cell had totally separated and there was now two separate daughter cells.
Answer:
<h2>Incomplete dominance</h2>
Explanation:
As given here;
Two pure line of four-o'clock plant, one having red flower and other having white flower, when they are crossed, they produce all pink progeny.
So, lets red as RR and white as rr
Cross between RR and rr
Here all offspring are Rr ( Pink ).
It's the result of incomplete dominance, in complete dominance the offspring is the intermediate of both the parents.
F2 generation:
As cross between Rr and Rr
progeny are: RR, Rr, Rr, rr
RR =red
Rr= pink
rr= white
So, red: pink: white = 25:50:25
