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
Answer;
Nasolacrimal duct
The runny nose you get when you cry is a result of your tears draining into the nasolacrimal duct.
Explanation;
The nasolacrimal duct is the duct that carries tears from the lacrimal sac of the eye into the nasal cavity.
Tears normally drain through small openings in the corners pf the upper and lower eyelids called puncta and then enters the nose through the nasolacrimal duct.
The puncta and the nasolacrimal duct are part of the nasolacrimal drainage system.
