A cross involving true-breeding, red snapdragons and true-breeding, white snapdragons produce all pink offspring because both ge
stiks02 [169]

Answer: The correct answer for the blanks are- 1) Dominant and 2) Blending of the trait.

Incomplete dominance produces a blend/ intermediate phenotype of both the parental phenotypes ( such as Pink snapdragon here) because none of the parental allele completely masks the effect of other.

As per the given information in the question, when true-breeding, red snapdragons are crossed with true-breeding white snapdragons, they produce pink colored offspring. This means that neither of the parental gene is dominant over the other.

When both are cross bred, they will represent a heterozygous state ( when alleles for both the snapdragons are present ), and they will produce an intermediate phenotype ( that is a blend of both the traits). This represents blending of the parental trait.

Which of the following promotes closure of the minivalves associated with lymph capillaries?
Molodets [167]

Answer:

increasing pressure inside the lymph capillary

Explanation:

Lymph is a fluid like the blood which carry the White blood cells which can fight against the infection. The lymph flows in separate vessels called lymphatic vessels.

The lymphatic vessel is very thin-walled smooth muscle containing tube-like structure which allows the transport of lymph.

The lymph vessel like blood vessel contains the valves called mini valves which prevent the backward flow of the lymph.

When the pressure in the tiny lymph capillaries which supplies lymph to the organs increases, the mini valves closes to prevent backflow of lymph and is the mechanism of lymph flow.

Thus, the selected option is the correct answer.

mafiozo [28]

Answer:

Gene.

Explanation:

Gene which is responsible for the production of spruceanol in the Peruvian Rosewood plant can be inserted in the host species in order to produce spruceanol  in large quantity so that we can used it as a drug that can cure antimalarial disease. There are certain genes that are responsible for the production of spruceanol in the Peruvian Rosewood plant so if we want to produce this spruceanol in other plants we have to transfer this gene to the host plant.
