Explanation:
A heterozygous type can be described as the type in which both the alleles of a gene are different. If both the alleles of a gene are similar in an organism, then the person is said to be homozygous for the trait.
In the above question, two heterozygous parents are to be cross- bred to check the probability of them producing homozygous alleles (AA).
A punnet square made will show the following results:
A O
A AA AO
B BA BO
Hence, there will be 25% chance that the offspring produced could be homozygous AA.
A mutation is any alteration in the genetic material (nucleotide sequence) of an organism. Mutations can be neutral, harmful, or beneficial depending on the environment in which the orgasm lives.
- In this case, the mutation IS HARMFUL because the organism is not more able to break down starch.
- The deleterious mutations are eliminated (selected) by natural selection.
- Beneficial germline mutations can eventually be inherited, increasing their frequency in the population.
