Complete question:
If the recessive allele for cystic fibrosis is represented as c, classify the following genotypes as homozygous dominant, homozygous recessive, or carriers: CC,Cc, and cc. State which one has the phenotype of cystic fibrosis.
Answer:
CC - homozygous dominant
cc - homozygous recessive
Cc - carriers
cc will have the phenotype
Explanation:
Cystic fibrosis is an autosomal recessive disorder that affects the production of mucus in the body, primarily affecting the lungs and digestive system.
Because it is autosomal recessive, an affected individual needs to inherit 2 copies of the faulty gene. The presence of just one normal copy of the gene is sufficient not to cause the disease
In genetics, the dominant allele is usually displayed as a capital letter and the recessive as a small letter. Homozygous means someone has 2 copies of the same allele, heterozygous means they have different alleles. Therefore, CC - homozygous dominant, cc - homozygous recessive, and Cc - carriers. Only those with a cc genotype will be affected, as the presence of one dominant allele is enough to block the phenotype
The statement that is FALSE is:
B) Matings between individuals with dominant phenotypes cannot produce offspring with recessive phenotypes.
For example, you can have a mating between an Rr parent and another Rr parent; they can still have a 25% chance of having an offspring with alleles of rr.
Answer: Postrefusal sexual persistence
Explanation:
Yudy is persistently trying to initiate sexual contact with Jenny in spite of saying no every time. He then tried calling her into his company then also she denied.
One day he made her drunk so that he can initiate sexual contact with her. This scenario represents the post refusal sexual persistence that even after saying no for multiple times she is being asked and forced for multiple times to have sexual contact with Yudy.
The thorax and forehead should be assessed for temperature in clients who abuse sedatives or hypnotics.
Excessive perspiration or diaphoresis is an abnormal condition observed in clients who abuse hypnotics and sedatives. In this case, the body temperature should be measured primarily in the upper thorax as well as the forehead.
The thorax and forehead are the most convenient places since it is easier to see excessive perspiration in those areas. In those who do not abuse sedatives or hypnotics, the rectal area, oral cavity, and axillae are frequently preferred sites for assessing body temperature.
