Imagine you are a plant breeder. Friends sent you two different varieties of a snapdragon flower; each have golden leaves rather
Neporo4naja [7]

Answer:

Complementation.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

A trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her. Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.

Artificial selection is also known as selective breeding and it is a process that involves humans (breeders) selecting the animal or plant with desirable traits in order to reproduce favorable offspring having phenotypic traits.

Complementation can be defined as a relationship between two strains of a living organism both having distinct homo-zygous recessive mutations and results in the expression of a wild-type phenotype when crossed or mated.

In this scenario, there are two different varieties of a snapdragon flower having golden leaves rather than green leaves. Thus, crossing two different varieties of golden snapdragons would produce offsprings that have green leaves.

Hence, the above breeding is an example of complementation.

What is the mass percent of hydrogen in ammonium phosphate, (NHÁ)ÀPOÁ?
Black_prince [1.1K]
The chemical formula of ammonium phosphate is (NH4)3PO4. There is 3*4=12 Hydrogen atom in one molecule ammonium phosphate. The total mass of one molecule is (14+4)*3+31+16*4=149. The mass of hydrogen atoms in one molecule is 3*4=12. So the mass percent of hydrogen is 12/149*100%=8.05%
