Question

classify if the recessive allele fibrosis is represented as c classify fibrosis is represented as c,classify the following genotypes

Answer 1

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
