The genotypes of the parents are Aa (heterozygous) and aa (recessive homozygous).
For example:
If the purple flower is dominant phenotype, then A is a dominant allele for it and Aa is a genotype which will give the purple colour.
In this case, white flower is recessive phenotype with aa genotype.
If we cross Aa x aa
<span>The offspring is going to be Aa Aa aa aa (half purple and half white)</span>
Mitosis form of cell division marks in an enlarged germ cell pool, Mitosis is a procedure where a single cell splits into two identical daughter cells (cell division).
<h3>What is mitosis and meiosis?</h3>
There are two kinds of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the procedure of making new body cells.
Meiosis is the kind of cell division that creates egg and sperm cells. Mitosis is a actual procedure for life.
Thus, Mitosis form of cell division marks in an enlarged germ cell pool, Mitosis is a procedure where a single cell divides into two same daughter cells.

Answer:
Sickle cell anemia is a genetic disease with severe symptoms, including pain and anemia. The disease is caused by a mutated version of the gene that helps make hemoglobin — a protein that carries oxygen in red blood cells. People with two copies of the sickle cell gene have the disease.
Explanation:
Hope thia helps :)
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.
