Normal gametes should contain one allele from each gene.
A non-gamete cell, or somatic cell, typically has two alleles for each gene, one inherited from each parent. This means that in diploid organisms, such as humans, somatic cells contain two sets of chromosomes, resulting in two alleles per gene. However, some organisms can have different ploidy levels, affecting the number of alleles present.
Heterozygous females produce two types of gametes with respect to a given gene. If we denote the alleles as A (dominant) and a (recessive), the gametes produced will be either A or a. This results from the segregation of alleles during meiosis, where each gamete receives one allele from the pair.
The process is called meiosis, specifically during the formation of gametes, where alleles segregate. Each gamete receives one of the two possible alleles for a given gene due to the law of segregation, which states that allele pairs separate during gamete formation. This ensures genetic variation in offspring when gametes combine during fertilization.
Four gamete types can be formed from the diploid individual TtPp. This is because during meiosis, the two parent alleles for each gene (Tt and Pp) will segregate into separate gametes, resulting in four possible combinations of alleles (TP, Tp, tP, tp).
An organism that is heterozygous for a gene can produce two different types of gametes due to the segregation of alleles during meiosis. Each gamete will carry one of the two different alleles present in the organism.

A non-gamete cell, or somatic cell, typically has two alleles for each gene, one inherited from each parent. This means that in diploid organisms, such as humans, somatic cells contain two sets of chromosomes, resulting in two alleles per gene. However, some organisms can have different ploidy levels, affecting the number of alleles present.
In the given genotype, which consists of three identical homozygous alleles (AA), there is only one type of gamete that can be produced. Since all alleles are the same (A), the only gamete type formed would carry the A allele. Therefore, the number of gamete types is one.
Heterozygous females produce two types of gametes with respect to a given gene. If we denote the alleles as A (dominant) and a (recessive), the gametes produced will be either A or a. This results from the segregation of alleles during meiosis, where each gamete receives one allele from the pair.
In a gamete (sex) cell, there are 23 chromosomes. A gamete is a haploid, or n, whereas a somatic (normal) cell is a diploid, or 2n, and has 46 chromosomes.

Mendel's Law of Segregation states that each individual has two alleles for a particular trait, and these alleles separate during gamete formation so that each gamete receives only one allele. This results in the random distribution of alleles into gametes and leads to genetic variation in offspring.
