The fact of the matter is, to be a good consulting psychologist, you need to be a good psychologist. I think itâs important to develop the broad base of understanding of human behaviors, research methodologies, clinical approaches, the fundamental building blocks.
In humans, free earlobes (E) are dominant to attached earlobes (e) and the presence of freckles (F) is dominant to the absence of freckles (f). If an individual heterozygous for both of these traits were to mate with an individual with attached earlobes and no freckles, what is the probability of having a child with attached earlobes and freckles? â 25% 9.
The genome in which a genotype is found can affect the expression of that genotype, and the environment can affect the phenotype. Not all pairs of alleles will have the same phenotype: dominance when AA = Aa in phenotype, A is dominant, a is recessive. An allele can be dominant over one allele but recessive to another allele. Model of dominance from enzyme activity: no copies produce no phenotype, one copy produces x amount of product and two copies produces 2x then the alleles are additive and there is no dominance (intermediate inheritance).
