Answer:

Since archaea are some of the oldest forms of life on Earth, the similarities suggest that some structures in eukaryotic cells, such as ribosomes, partially evolved from archaea.

Assuming that this is the theory of endosymbiotic creation of eukaryotes , it supports it by showing that ancient prokaryotes such as archae have ribosomes that could have joined together, as the theory states to create the eukaryote's ribosomes that they have today (because they're so similar.)

What are the possible phenotypes of chicken offspring if one parent has black feathers ( FB ) and one parent has white feathers
Salsk061 [2.6K]

Answer:

None. Chickens have feathers not fur.

Now to color. The male usually determines color so without that information it is hard to answer with any authority.

In most crosses if the male is black and the hen is white you will get some black chicks and all will have white/black

variations.

If the male is white and the hen is black you will get some all

white with others showing black and white.

If the breed is Leghorn, even if the rooster is black you will

get mostly white chicks with some throwbacks in red and buff.

1. Which blood types are dominant?
marishachu [46]

Answer: 1). A and B are both dominant (because A and B are codominant to one another)

2). E. All of the above

Explanation:

1). From the image above, A and B are both dominant because they are equally expressed when they occur in a pair (when they occur as blood type AB), also they are dominant because each of them expressed itself when it occurs in a pair with a recessive allele (IAi and IBi).

2). The children of a father with A blood and a mother with B blood will have all the four blood types: A, B, AB, and O. If each parent has a recessive allele, that is if each parent is heterozygous for his/her blood type (IAi for the father and IBi for the mother), the cross between them will produce all the four possible blood types.

See the attached punnet square for more information.
