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.
Answer:
Autonomic
Explanation:
<em>The autonomic nervous system is a section of the peripheral nervous system that specializes in the regulation of various body processes that requires no efforts. </em>
The system operates by collecting information from the external environment and the body of living organisms. It is further divided into 3 sub-sections according to their specialization namely; the sympathetic, the parasympathetic and the enteric nervous system
B) it will starve
happy thanksgiving : )
Answer:
One parent is hybrid, one is recessive
Explanation:
If you do the punnet square, you will notice that there are two outcomes, and that they have a similar proportion, this is only possible if you math a recessive mouse (lets say the recessive allele is white), and a hybrid, that will show the dominant trait (lets say that black is dominant).
So: P=black and p=white
Pp x pp=
2/4 Pp(looks black) and 2/4 pp (looks white)
the answer is g....................
