The nucleus contains the DNA and acts like a control center of the cell.
Here we can see that 7 phenotypes appeared in F2 generation, so the number of genes involved is 3 and alleles is 6. Contribution per allele = 4 cm Base contribution = 6 cm
Genotype of Harvey = aa bb cc Genotype of Erma = AA BB CC
Number of dominant alleles if length is
18 cm = 18-6 / 4 = 12 / 4 = 3.
F1 generation genotype = Aa Bb Cc This clarifies why the length is 18 cm, as there are three dominant alleles.
seven 1. It is likely that there are gene pairs in this cross. There are
categories of phenotypes. The genotypes of the parents would be combinations of alleles that would produce a 6 cm ( aabbcc ) tail and a 30 cm) tail, whereas the 18 cm offspring would have a genotype of AaBbcc.

C, the roots are underground so have less impact on photosynthesis.
Answer:
The difference between mitosis and meiosis is that....
<u>Mitosis produces two daughter cells with the same number of chromosomes as the parent cell. </u>
<u>Meiosis results in four daughter cells harboring only half of their parent's chromosomes, which underwent recombination.</u>

Brainstem.
The brainstem is the portion of the central nervous system that's located between the spinal cord and the d<span>iencephalon and it occupies the posterior cranial fossa in front of the cerebellum. It is divided into three parts: the rachidian bulb, the pons, and the midbrain.
It's in the brainstem that can be found the commanding nucleus of the most basic homeostatic mechanisms such as heart rate, breathing, and n</span><span>ociception.</span>
