Question

question 19 (2.5 points)
split-brain patient g.c. sees a fork on the right side of their body (seen with the left hemisphere). how will the patient typically respond?
g.c. can draw, point or pick up the object but cannot say it
g.c. will verbalize \fork\ aloud
g.c. will verbalize \knife or spoon\ aloud (a related item)
g.c. will ignore the stimulus because the brain does not see it
question 20 (2.5 points)
you breed a brown mouse with a white mouse. if four out of their five offspring are brown, you would guess that the gene for brown is and the gene for white is .
recessive; dominant
dominant; recessive
the genotype; the phenotype
the phenotype; the genotype

Explanation:

Question 19

In split - brain patients, the left hemisphere is responsible for language. When a stimulus is presented to the right side of the body (processed by the left hemisphere), the patient can verbally identify it. So when G.C. sees a fork on the right side (processed by the left hemisphere), they can verbalize "fork" aloud. The other options are incorrect: the first option is for stimuli processed by the right hemisphere (non - verbal responses), the third option is incorrect as there's no reason to verbalize a related item, and the fourth option is wrong as the brain does see the stimulus.

In genetics, a dominant allele is expressed in the phenotype even when a recessive allele is present. When a brown mouse and a white mouse are bred, and most (4 out of 5) offspring are brown, it means the brown trait is expressed more. So the gene for brown is dominant (it masks the white gene), and the gene for white is recessive (it is masked by the brown gene). The options with genotype and phenotype are incorrect as genotype refers to the genetic makeup and phenotype to the physical appearance, not the dominance relationship here.

Answer:

B. G.C. will verbalize "fork" aloud
