Normal gametes should contain one allele from each gene.
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.

The process of allele segregation during gamete formation is determined by the random assortment of chromosomes during meiosis. Homologous pairs of chromosomes separate independently, and each resulting gamete randomly receives one copy of each chromosome. This random assortment leads to the random segregation of alleles, determining which allele of each pair goes into a gamete.
Gametes carry half the number of normal chromosomes as a body cell. Since there are normally 46, this means there are 23 chromosomes in a human gamete.

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.
This is Mendel's first law, the law of segregation.

A normal mouse gamete would have 19 autosomes.
The three Mendelian theories are the Law of Segregation, which states individuals have two alleles for each gene and these alleles separate during gamete formation, the Law of Independent Assortment, which states alleles of different genes segregate independently during gamete formation, and the Law of Dominance, which states that one allele can mask the presence of another in the phenotype.
