A geneticist describes the phenotype of an individual with the alleles dd as homo-zygous recessive. In heterozygous individuals, it is masked by the dominant allele.
<h3>Dominant and recessive alleles</h3>
In diploid organisms, an individual receives two gene forms or 'alleles' for the same gene locus.
An individual is heterozygous when receives two different alleles for the same gene locus, whereas an individual is homo-zygous when receives the same alleles for a gene locus.
In cases of complete dominance, the dominant allele completely masks the recessive allele in heterozygous individuals.

Answer:
A. = Shale
B = Granite
C = Sandstone
D = Limestone
Explanation:
Based on the weathering patterns, the rock type shown in each photo can be concluded to be as
A. = Shale: this is a form.of sedimentary rocks. It is formed from finely textured materials. Such as clay, quartz, and calcite minerals
B = Granite: this is derived from igneous rock. It has coarse texture features.
C = Sandstone: it is formed by a sand-sized grain of natural earth materials that form together
D = Limestone: it is also a form of sedimentary rock. It contains a large quantity of calcium carbonate it is formed from materials such as ancient corals and skeleton.
