Alleles are letters that represent dominant and recessive traits.
A capital letter represents a dominant trait
A lowercase letter represents a recessive trait.
Dominant traits over shadow the recessive ones. This is known as complete dominance.
Referring to your questions let's us the alleles HH, Hh, and hh for the height of the pea plants.
But what do those letters mean?
HH = homozygous dominant (Tall)
Homo means same.
hh = homozygous recessive (Short)
Now this is different: here's Hh.
There's a capital AND lowercase letter.
This means that the plant carries the gene for tall and short plants, and can pass on either trait to the offspring.
BUT the dominant always over shadows the recessive. So Hh is a tall plant.
Hh = heterozygous (hybrid) (Tall)
You can interpret hetero meaning different.
Now I hope you're with me!
For question two it asks if a short plant can ever be a hybrid.
Referring to what I just said, that answer would be no.
Because there is no dominant trait to over shadow the recessive.
And short plants have the hh alleles, and they are homozygous NOT heterozygous (hybrid).
I hope this helps, and makes sense! If you have any questions please let me know. Genetics can be confusing.
Ultraviolet, or UV, rays ,these are the rays that can cause sun damage to a person's skin in the form of sunburn. While a person cannot detect the sun's UV rays, he or she can detect the infrared rays via the sensation of heat.
Gamma rays - these are most often found in the core of the sun, during fusion. These rays lose frequency as they move towards the surface.
X-rays -
X-rays are emitted by the sun during solar flares.
Visible light -
visible light are radiation waves that are in the frequency range easily seen by the naked eye. Different wavelengths in the visible light spectrum make up different colors.
Microwaves -
microwave radiation waves emitted by the sun are primarily absorbed by the Earth's atmosphere.
Radio waves -
these waves have the longest wavelengths, and the sun is the brightest source of radio waves.
I think personally it looks fine.
When placing a red blood cell in any hypertonic solution, there will be a movement of free water out of the cell and into the solution. This movement occurs through osmosis because the cell has more free water than the solutio
