Answer:
During the 20th century, a belief called behaviorism was popular. Behaviorism was a major change from previous theoretical perspectives, rejecting the emphasis on both the conscious and unconscious mind.
Explanation:
The discarded theory of blending inheritance most closely resembles incomplete dominance.
<h3>
What is blending inheritance?</h3>
- An antiquated biological notion from the 19th century is the concept of blending inheritance.
- According to the hypothesis, children inherit any trait by averaging the values of their parents for that trait.
- According to the theory of blended inheritance, an offspring combines the values of both parents for a given attribute.
- As opposed to blended inheritance, particulate inheritance states that a child inherits individual units or genes from each parent.
- Offspring thus combines the traits of both parents.
- Incomplete dominance is the term used to describe phenotypic "blending" of two features, which implies that neither trait is truly dominant over the other.
- The manifestation of phenotypic traits that are intermediate between those of the parents, such as pink flower color from red and white parents.
- Inheritance was a now-discredited hypothesis that claimed children's genetic make-up was a pure admixture of their parents'.

Answer:
Genetic drift
Explanation:
Genetic drift can also be referred to as allelic drift, it refers to the variation in allelic frequencies within a particular population over a period of time. It can also be referred to as the random fluctuations in the number of genotypes within a population. Genetic drift is not influenced by the environment and is usually more pronounced in a small population of organisms.
For example, a population of birds can consist of green feathers and blue feathers with the green feathers as the dominant allele, but as a result of random fluctuations, the offspring may all be with green feathers and hence could eliminate or reduce the allele responsible for blue feathers over time.
