Answer:
The question lacks options, the options are:
parents?
A.100% red/white-feather chickens.
B.50% white-feather chickens and 50% red/white-feather chickens.
C.33% white-feather chickens, 33% red-feather chickens, and 33% red/white-feather chickens.
D.25% white-feather chickens, 25% red-feather chickens, and 50% red/white-feather chickens
The Correct answer is D
Explanation:
According to the question, the hybrid chicken has a mixture of red and white feather phenotypes expressed at the same time. This tells us that the red and white alleles are CODOMINANT in the chicken i.e. none is dominant or recessive over the other.
Let's assume that (R) allele is the red feather colour while (r) allele is for white feather colour. Therefore, the red/white feathered chicken will have a Rr genotype. In a cross between two red/white feathered chicken (Rr), the following offsprings will be produced RR, Rr, Rr and rr
RR- Homozygous red feather d chicken (1/4 × 100=25%)
Rr- Hybrid Red/White feathered chicken (2/4 × 100=50%)
rr- Homozygous white feathered chicken (1/4 × 100=25%)
Answer:
D) Hydrogen bonding
Explanation:
A hydrogen bond is a kind of electrostatic force of attraction between the hydrogen atom and a more electronegative atom e.g. nitrogen, fluorine, and oxygen.
It is a weak force of attraction.
In size-exclusion chromatography, the attraction that exist between the proteins and dextran is hydrogen bonding.
The several hydroxyl groups thats seen in dextran accounts for why hydrogen bonding exists between dextran column material and the protein.
Answer:
True
Explanation:
If a trait does not help or hurts the organism, it will be less likely to survive and as a result will be less likely to be passed on.
Answer:
the branch of science concerned with classification, especially of organisms; systematics.
Explanation:
Answer:
The monomers combine with each other via covalent bonds to form larger molecules known as polymers.
Explanation:
A monomer is a type of molecule that has the ability to chemically bond with other molecules in a long chain; a polymer is a chain of an unspecified number of monomers. Essentially, monomers are the building blocks of polymers, which are more complex type of molecules
and example of such is seen in several monosaccharides (glucose, fructose)joining together to form polysaccharide like starch
