Answer:
(4) is bred and the trait is capable of being inherited
Explanation:
<u>Mutation generally refers to a sudden change to the DNA sequence in the genome of an organism.</u>
Since, DNA is the molecules responsible for heredity and the inheritance of traits by offspring from their parents, a mutation should be inheritable.
<em>Hence, if a sudden appearance of hairlessness in one of the puppies is observed by a dog breeder, he/she can effectively conclude that the situation is caused by a mutation if the affected dog is bred with another dog and the hairlessness is observed in any of the resulting progeny.</em>
Option 4 is the correct option.
Answer: Mutation can affect an organism by resulting to a change in the number and structure of chromosomes (chromosomal mutation). A typical example of this type of mutation is Down's syndrome where the individual contains 47 instead of 46 chromosomes.
Mutation can also result to a change in the nucleotide sequence of the DNA molecule in a particular region of a chromosome(Gene mutation) an example of genetic mutation is sickle cell anemia

Brown eye-color is dominant while the blue-eye color is recessive. Therefore, the homozygous for brown color is BB and the homozygous for brown color is bb. Thus, the heterozygous will be Bb (brown color). Since James has blue colored eyes a child of Jenna (brown color) and bill (blue color) then it means Jenna is heterozygous (Bb). Jenna is described as being a carrier of the allele for blue eyes.
