Answer:
haploid (n) or triploid (3n)
Explanation:
If none of the chromosomes separate during meiosis, the resulting gametes will either lack chromosome or have diploid number (2n) of chromosome instead of a haploid number.
If an egg without chromosome (o) fertilizes a normal sperm (n), the resulting zygote will have haploid number (n) of chromosome.
If an egg with diploid number of chromosome (2n) fertilizes a normal sperm (n), the resulting zygote will be a triploid with 3n number of chromosome.
Answer:
It would most likely render the protein nonfunctional or mis-functional.
The mutation could result in three outcomes:
- Silent mutation, which changes the codon to the same amino acid. (AAA->AAG, both are lysine). But since the problem specified that it has a "slightly different amino acid sequence," we can assume this doesn't happen.
- Nonsense mutation, which changes a codon to a stop codon. This would end the chain of amino acids, making the protein potentially nonfunctional.
- Missense mutation, which changes a codon to another completely different codon. This can be harmful, as in sickle-cell disease, where just one amino acid, glutamic acid, is changed to valine.
