Mendel Claimed That Transmission from Parent to Offspring of Alleles

question 3

Multiple Choice

Mendel claimed that transmission from parent to offspring of alleles of a given gene is independent for each gene and its alleles. What does this mean?

• A) If a parent has the genotype Aa for one gene and aB for another gene, the a allele is more likely to be passed on because it corresponds to a dominant allele on another gene.
• B) Dominant alleles in different loci are organized to enhance their likelihood of being passed on, a process called codominance.
• C) Dominant alleles act independently of recessive alleles.
• D) With the exception of genes on the same chromosome, the probability of transmission of a gene is unrelated to the transmission of other alleles on different genes.

Definitions:

Operant Behavior

A concept in behavioral psychology referring to behavior that is controlled or influenced by its consequences, including rewards and punishments.

Primary Reinforcer

A stimulus that satisfies basic survival instincts such as food, water, and warmth, and doesn't require learning to become effective.

Conditioned Reinforcer

a stimulus that gains its reinforcing power through association with a primary reinforcer, used to increase the likelihood of a specific response in operant conditioning.

Reinforcing Power

The ability of a stimulus to increase the likelihood of the repetition of a behavior when it is presented following that behavior.
