The genotype of a heterozygous individual is Aa, of a homozygous dominant is AA, and of a homozygous recessive individual is aa.
<h3>What is a dominant genotype?</h3>
A dominant genotype is a set of gene variants characterized to have dominant alleles that mask the expression of recessive alleles in heterozygous individuals in cases of complete dominance.
In conclusion, the genotype of a heterozygous individual is Aa, of a homozygous dominant is AA, and of a homozygous recessive individual is aa.

Answer:
The correct answer is insight learning.
Explanation:
A kind of problem-solving or learning, which takes place instantaneously by comprehending the various aspects of an issue in spite of going through trial and error procedure is termed as insight learning. The given case is a clear illustration of insight learning. This form of learning takes place if one finds a novel way to solve an issue without the help of any other elements.
The individual in the given case used the help of a cut potato to collect the broken pieces of a lamp, which is an illustration of insight learning. The person has used his instinct and has not used any outside source for doing what he had done.
The complete question is :
As an epidemiologist you are going to investigate the effect of a drug suspected of causing malformations in newborn infants when the drug in question is taken by pregnant women during the course of their pregnancies. As your sample you will use the next 200 single births occurring in a given hospital. For each birth a medication history will be taken from the new mother and from her doctor; in addition, you will review medical records to verify use of the drug. [N.B.: These mothers are considered to have been followed prospectively during the entire course of their pregnancies, because a complete and accurate record of drug use was maintained during pregnancy.] The resultant data are: Forty mothers have taken the suspected drug during their pregnancies. Of these mothers, 35 have delivered malformed infants. In addition, 10 other infants are born with malfunctions. What is the relative risk between exposure to the drug and malformations?
Answer:
14
Explanation:
- The relative risk is a measure that is used to calculate or compare the likelihood or the chance that an event would occur while comparing the two groups.
- To calculate the relative risk, the probability of an event occurring in one group is compared with the probability of the event occurring in another group and this is done by dividing the probability of one group by another.
- The value of relative risk is always either zero or greater than zero but it cannot be negative.
- The value 1 indicates neutrality.
- The probability of an event = no. of favorable outcomes/ total no. of outcomes
- For the given question, 35 mothers out of 40 delivered infants that were malformed, so the probability of delivering malformed infants is 35/40.
- Out of the 200 births, 40 have occurred so total births left is 200 - 40 = 160
- Therefore, the probability of the second event is 10/160.
- Therefore relative risk is = (35/40)/(10/160) = (0.875/0.062) = 14
