When the effects of genes add up to make the phenotype, they are called additive genes.

Answer:

additive genes.

Explanation:

Additive genes are found in Polygenic Inheritance.

In this pattern of inheritance, the phenotype is conditioned by two or more pairs of allele genes, one of which is called the additive gene, and the other is the indifferent or nonadditive gene. Each additive gene present in an individual determines the increase in phenotype expression intensity, no matter which pair this additive gene is. Nonadditive genes add nothing to phenotype expression.

What qualities of metamorphic rocks make them very useful and desirable for building?
sashaice [31]

Slate starts out as shale under the surface of the Earth before its metamorphosis. It is typically gray in color and splits along long flat planes. It is also does not allow water or other liquids to pass through it. Slate is most often used as a roofing material, decorative gardening stone and a base for snooker tables. In the Victorian era, it was commonly used as a writing board.

Marble is another one of the metamorphic rocks and is a metamorphosed limestone. It has a hard crystalline rock appearance and was the stone of choice in ancient Greece. In fact, more than 22,000 tonnes of marble were used to build the ancient Greek Parthenon and marble remains a popular building and sculpture material today. It can also be ground down to make cleaning products or soaps.

Schist is another metamorphic rock that is formed from either mud or shale. However, it is formed at a much higher temperature than slate is. Schist is a fairly weak rock so it does not make for a good building material. It is used for paving and occasionally sculpture.
