Answer:

B.) One dominant and one recessive allele

Heterozygous genotypes occurs when the two alleles at a particular gene locus are different. A heterozygous genotype may include one normal allele and one mutation, or two different mutations. The latter is called a compound heterozygote.

The two alleles representing the trait are different (e.g. Pp for purple color). Although the pea plant appears purple in color (its phenotype is purple), its genotype (genetic make-up) is a mixture of a dominant “P” and a recessive ‘p” trait.

Explanation:

Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype, where an individual inherits identical forms of a particular gene from each parent.

earnstyle [38]

Answer:

c) The occupational health nurse should discuss HIV status with the client.

Explanation:

If you are a nurse you should be very careful when administering vaccines to a patient. Besides taking proper care in the administration of the vaccine, the nurse must be careful not to receive a needle injury to the patient, because some diseases are caused by contact with fluids of the infected human body, one of these diseases is AIDS, caused by HIV virus.

In the case exposed in the question, the professional should act calmly and contact the occupational health nurse so that this nurse contacts the patient to discuss the HIV status with the patient. The educational health professional is responsible for this. The attending nurse should not perform an HIV test without the patient's authorization, should not personally ask the patient to take an HIV test, nor can they inform the patient about the need for this test because these practices are considered unethical within of the profession.
