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:
Origin of Species was a book that was published in 1859 by Charles Darwin on human evolution. This theory was based on natural selection.
Explanation:
The evolution theory was first proposed by Darwin in 1856 in his book Origin of Species. In this theory, Darwin explains the changes in species over time result in the changes in the traits and heritable qualities. Evolution occurred by natural selection. In this theory, scientists show two main points that, all species are connected on this earth and the diversity in the population is the result of the modification in traits by time.
For Example, one study on 1900 students on human evolution was published in the journal " Personality and Individual Differences". According to this research, people are hard to find their soul mate because the changes are very rapid in traits.
