It’s “one of her parents had type B blood and the other type A blood.”
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:
homology.
Explanation:
These similarities in structural are an example of homology because human arms, bat wings, and dolphin flippers are different organisms that have the common ancestor. The similar bone structure of different organisms and different its function is due to common ancestor. Homology similarity of the structure and physiology of different species of organisms due to their descent from a common evolutionary ancestor so we can say that these structural similarities are an example of homology.
Oxidation occurs at the anode.
For both electrochemical cells, this occurs where the cathode and anode is where half reaction occurs.
Hope this helps!
