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.
Answer:
Vacuum
Explanation:
A vacuum is usually defined as a space in which there is an absence of matter. It can also be said that there is an extremely low amount of pressure due to which the particles present in it are not affected by any type of process that occurs in space. The value of pressure is lower than the value of normal atmospheric pressure.
For example, sound cannot travel in space because there is no medium such as water and air through which the sound waves can propagate.
