When an adolescent's newly sophisticated metacognitive capability causes him or her to become self-absorbed and believe that the world is focused on only him or her, this is called <u>b) adolescent egocentrism</u>.
<u>Explanation</u>:
Adolescent egocentrism is the term used by psychologist to describe the incapability of young people to differentiate between their perception of what people think about them and what others actually think in reality.
The adolescent egocentrism concept was expressed by the psychologist David Elkind. Adolescent egocentrism is found in children of age 10-14 years. They always think about what others will think about them. The young people consider themselves as center of attention and never focus on others views.
When a person possesses two different alleles at the same locus, and both alleles are expressed in the phenotype, this is called Codominance.
Alleles
According to leading textbooks on genetics and evolution, an allele is a variant of the same sequence of nucleotides at the same location on a lengthy DNA molecule. "A locus is the chromosomal or genomic site of a gene or other genetic element, and alleles are variant DNA sequences at a locus." The majority of alleles observed have little or no effect on the function of the gene product for which they code. Various alleles can, however, result in variable observable phenotypic features, such as different colouring. Gregor Mendel's discovery that the white and purple blossom hues of pea plants were caused by a single gene with two alleles is an example of this.
