A trait I which the alleles are not dominant over one another
JulsSmile [24]

Answer:

They are co-dominance and incomplete dominance.

<h2 />

Explanation:

Co-dominance occurs when both alleles in a heterozygous genotype for a trait are both equally expressed. An example is the human AB blood group, in which both the A and B alleles are equally expressed.

Incomplete dominance occurs when the heterozygous genotype for a trait is expressed as a blend. An example is blue feather color in chickens, in which a black allele and white allele together are expressed as blue feather color.

Xelga [282]

Answer:

I agree and disagree with his statement.

Explanation:

We all know that the blood type AB is the universal recipient, so we know that this bloodtype can recieve any kind of blood. AB-type blood doesn't fight off anything because it has all of the antibodies needed. We also know that type O is the universal donor, meaning that this blood can be donated to anyone. This bloodtype doesn't have antibodies, so nothing will go wrong. However, for the other bloodtypes, yes, things have to be matched carefully. Type B blood can't be given type A blood, and so on. Another thing you have to think about is the Rh factor, which is the +/- after blood types. Rh+ bloodtypes can recieve both Rh+ and Rh- bloodtypes, but Rh- bloodtypes can only recieve Rh- bloodtypes. There are also graphic tables that will help answer this question if you're a visual learner!

I hope this helps, sorry it was a bit late!

Which of the following species is diamagnetic? View Available Hint(s) Hint 1. How to determine magnetism Which of the following
m_a_m_a [10]

Answer:

Explanation:

Cl = 1s2 2s2 2p6 3s2 3p5

Al = 1s2 2s2 2p6 3s2 3p1

Fe2+ = 1s2 2s2 2p6 3s2 3p6 4s2 3d4

S2- = 1s2 2s2 2p6 3s2 3p6

Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. If all electrons in the particle are paired, then the substance made of this particle is diamagnetic.

S2- is diamagnetic because of its paired electrons in the outermost shell.
