Answer:
If a father has a blood type AB and his wife has a blood type O, their children could be a blood type A or B, with a 50/50 chance.
Explanation:
Blood type and heredity are determined by surface antigens on the red blood cell, called A and B. The surface antigens provided by each parent are genetically encoded:
- <em>Blood type A </em><em>corresponds to the presence of antigen A, and its genotypic expression can be A/A or A/O.
</em>
- <em>Blood type B</em><em>, whose genotype is B/B or B/O, is due to the presence of a gene containing the B antigen.
</em>
- <em>AB blood</em><em> —due to co-dominance— has a gene for A and another for B, with genotype A/B.
</em>
- <em>Blood type O</em><em>, characterized by the absence of surface antigens, behaves as a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O.
</em>
In the case posed the father has the blood type AB and the mother the blood type O, so:
- ♂ blood type AB, alleles A|B
- ♀ blood type O, alleles O|O
The crossing can be seen graphically in the diagram:
Alleles A B
O A|O B|O
O A|O B|O
According to this, the offspring of this man and his wife could be:
- Children with blood type A, genotype A|O, 50%
- Children with blood type B, genotype B|O, 50%

The correct answer is option c, which is preconventional of moral reasoning.
It is because preconventional of moral reasoning because according to Kohlberg's theory of moral development. it is the first stage that clearly defines the moral ethics that lasts up to the age of 9 including ethics like breaking of rules without concern.
<h3>What is
Kohlberg's theory of moral development? </h3>
Kohlberg's theory of moral development focuses on how children develop morality and moral reasoning. Kohlberg's theory suggests that moral development occurs in a series of six stages. The theory also suggests that moral logic focuses primarily on seeking and supporting justice.
Thus it concludes that preconventional moral reasoning is correct as it clearly describes the behavior of moral development by explaining the idea to avoid punishments.
