Quartz is an important mineral in mafic rocks like basalt and gabbro. The given statement is false.

<h3>What is mafic rocks?</h3>

Mafic minerals and rocks are silicate minerals or igneous rocks that are high in magnesium and iron.

The majority of mafic minerals are darker in color, and some of the most common rock-forming mafic minerals are olivine, pyroxene, amphibole, and biotite. Basalt, diabase, and gabbro are examples of common mafic rocks.

In geology, mafic rock is an igneous rock monopolized by the silicates pyroxene, amphibole, olivine, and mica.

These minerals are rich in magnesium and ferric oxides and contribute to the dark color of mafic rock.

Thus, the given statement is false.

In clover plants, the pattern on the leaves is determined by a single gene with multiple alleles that are related in a dominance

igomit [66]

Answer:

The correct answer is -

a. 7

b. 7 (p1p1, p1p2, p1p3, p1p4, p1p5, etc

c. p7 is abundant

Explanation:

According the question the dominance of the big leaves is p7 > p6 >p5 >p4 >p3 >p2 >p1 where 1 represent least dominance and 7 represent most dominance

let represent the phenotype with the numbers 1 to 7 and genotype with a combination of these numbers so the genotype in respect of phenotype would be :

p7p7,p7p6, p7p5, p7p4, p7p3, p7p2, p7p1 - most dominant 7

p6p6, p6p5, p6p4, p6p3, p6p2, p6p1 - 6

p5p5, p5p4, p5p3, p5p2, p5p1 - 5

p4p4, p4p3, p4p2, p4p1 - 4

p3p3, p3p2, p3p1 - 3

p2p2, p2p1 - 2

p1p1- 1 least dominant

Thus, there are 28 different combinations or patterns of genotypes. 7 phenotypes patterns.
