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

Sea otters tend to inhabit the shores of the pacific (sometimes rivers, ponds, or lakes), a favorite habitat is the kelp forests on the coast of California. Mother otters even tie their babies (and sometimes themselves) in kelp leaves, keeping them near and preventing floating away when diving for food. This is a clear sign of intelligence, and they classify as mammals. Otters stay in groups led by a dominant male, but sometimes females will leave with their babies, or males will depart in search of their own group to manage.

For agricultural uses. For example: country or area with low precipitation and high droughts will starve if they don't have plants that can survive the harsh conditions such as genetically modified crops being able to take in less water than non genetically modified crops.
C is the answer to this question.
