Mitosis is the process of cell division that creates a new cell identical to the original. Somatic cells, such as muscles, hair and skin, undergo mitosis regularly in humans and other organisms. This is an important type of cell division needed to facilitate the repair of damaged cells, growth and replacement of old cells with new ones.
When a new cell is created, it must have the same library of genetic information all other cells in the body have access to. Because all the material in the new cell must come from the first cell, the original cell must make a copy of its DNA before completing the process of mitosis. These two sets of DNA only exist for as long as it takes the cell to undergo mitosis, which can be anywhere from 30 to 90 minutes in certain human cells. When the cell division is complete, both of the cells have a single identical copy of DNA.
I'm going to use the letter W for this
Going by the question, white is the dominant trait.
WW = white
Ww = speckled
ww = black
4 chickens would be speckled because 50% of the punnet square is Ww
Answer:
lightbulb?
Explanation:
a lightbulb will run out but can last a while
I think at 15 days because that is when it goes down
Answer:
b. FD
d. Fd
c. Dd
h. dd
Explanation:
From the given information:
We are given a dihybrid cross that comprises two traits. The crossing exists between two heterozygous white disc-shaped traits i.e. FdDd.
If the parent self crossed, the gamete combinations for the F1 generation are:
F d
D FD Dd
d Fd dd
Therefore, the gametes combinations are four potential and feasible combinations of FdDd that can enter into the Filial generation crossing.
