The main functions of Mitosis are growth and repair.
Cells must perform this to where they can grow or repair. Some cells you cannot regrow nor repair because they are already fully mature, you'll just halve to take care of them.

Answer:
Option-D
Explanation:
In the given question the genotype of parental allele is- AbaB X AbaB. The alleles formed will be- AB, Ab,aB, ab in which the crossover allele will be AB and ab.
1. Unlinked genes
Now of these alleles are unlinked then the alleles will assort independently of each other therefore performing the punnett square we will get dihybrid ratio as 9:3:3:1 in which
1. A_B_ are 9
2. aaB_ are 3
3. A_bb are-3
4. aabb- 1
Since the crossover allele are AB and ab therefore A_B_ are 9 and aabb- 1 represent recombinant genotype.
2. Linked genes
When the genes will be linked then chances of crossing over will be reduced as a result of which only two type of allele will be formed which are- Ab and aB and the recombinant frequency will become less.
Crossing these allele will form Aabb
, AaBb
, AaBb and aaBB genotypes.
The recombinant ratio will decrease as A_B_ is 2 and aabb is not present.
Thus, option-4 which states that the unlinked ration is 9:3:3:1 and linked ratio is <9: >3: >3: <1 is correct.
Answer:
I think the answer is that prokaryotes have a nucleus and eukaryotes do not.
Explanation:
It is the first thing I think of when I think of a difference between the two.
About 0.3 percent is about the safe amount of water humans may consume, the other 99 percent is in oceans, soil, icecaps, and floating in the atmosphere.
Answer:
True
Explanation:
An allele refer to two alternative forms of the same gene. An allele is a pair of genes found on a given chromosome. Usually, every allelic pair has one which is dominant and one which is recessive.
The dominant allele is expressed while the recessive allele is not expressed.
The colour of the pea plant is controlled by a pair of alleles wherein purple (P) is dominant to white (p).
The expressed colour of the pea plant(phenotype) is dependent on the arrangement of the genes(genotype) of the pea plant.
