True. After the first meiotic division, the cells are diploid, because the chromosomes are duplicated.
<h3>What is meiotic division?</h3>
- Meiosis is a type of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell.
- This mechanism is essential for the development of egg and sperm cells for sexual reproduction.
- The two separate cell division processes are meiosis and mitosis.
- The process of making new cells for the body, known as mitosis, is usually meant when the term "cell division" is used.
- Meiosis, a cell division process, is what creates egg and sperm cells.
- Mitosis is an essential biological mechanism.
- Two cellular divisions make up the meiotic process: To reduce the number of chromosomes in half, pairs of homologous chromosomes are divided during the first meiotic division.
- During the second meiotic division, sister chromatids are split apart.

Answer:
The mutant allele has stayed around because it protects its carrier from dying of malaria.
Explanation:
The sickle-cell allele is extensively recognized as a modified that reasons red blood cells to be distorted into a sickle form when deoxygenated in SS heterozygotes, in which A designates the non-mutant form of the β-globin gene, and also delivers confrontation to malaria in SS heterozygotes. Malaria is related with enlarged severe stage protein attentions and severe malaria rises erythrocyte inflexibility, which may disturb the association among haemoglobin and haematocrit.

Explanation:
The cells store glycogen and neutralize toxins and are present in coelomic fluid of some annelids. They are yellowish in colour due to the presence of yellow granules called chloragosomes.
These cells are derived from the inner coelomic epithelium, and help in excretory functions, as most commonly demonstrated in earthworms.
