No - some traits are polygenetic (such as for skin color, eye color, hair color, etc.) and will have multiple alleles.
For each trait, a gamete has one allele. It is haploid.
Every sex cell has one allele for each trait. after meiosis, pairs of chromosomes separate and alleles for each trait also separate into different sex cells.
Non-Mendelian traits are:A trait with no clearly dominant alleleA trait with four allelesA trait controlled by many genes
Genotypes consist of two alleles for every trait. You inherit one allele from one parent, and another from the other parent.
An organism has two alleles for one trait. If the two alleles are the same, the individual is homozygous for that trait, and if they are different, the individual is heterozygous.

Each gene has a dominate and recessive allele, so there are two types of alleles in each gene. The dominate allele is stronger than the recessive allele unless there are two recessive alleles.

No, often many other alleles will also determine the same trait. For example, many alleles put together will determine a person's skin color.
