It is accepted to be fact by those who accept it to be fact, until further experimentation or research can prove otherwise
Answer:
•The gene responsible for the albinism is sex-linked
•The gene responsible for the albinism is recessive
• The pedigree is contained in the attached file
Explanation:
The gene responsible for the trait of albinism is said to be sex-linked because all those that were mentioned with the expression of albinism were females
The gene responsible for the trait of albinism is also said to be recessive because it was found to be rarely expressed and this goes in line with the definition of a recessive gene, which says; a recessive gene is the gene that remains unexpressed ( phenotypically) in the presence of it counterpart ( the dominant gene) in an allelic pair.
