Dominant and Recessive
"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).
If parents supply different alleles for a certain trait to their offspring, the offspring are described as heterozygous for that trait. This means they possess two different alleles, one inherited from each parent. In contrast, if the offspring received the same allele from both parents, they would be termed homozygous for that trait. The expression of the trait may depend on whether the alleles are dominant or recessive.
Homozygous is a description of alleles that are the same (HH,hh): either both dominant or both recessive. Heterozygous is a description of alleles that are different (Hh): one dominant, one recessive.
Homologous chromosomes are similar in terms of size, shape, and genes, but they are not similar in terms of the specific alleles they carry. Each homologous chromosome may carry different alleles for the same gene, leading to genetic diversity.
The allele that is expressed in an individual is referred to as the dominant allele. This allele masks the effect of the recessive allele when present.
In terms of a population, evolution is just the change of allele frequencies over time. Natural selection can cause certain advantageous alleles to increase in frequency, and detrimental alleles to decrease in frequency.
Homozygote: (genetics) an organism having two identical alleles of a particular gene and so breeding true for the particular characteristic. Heterozygote:(genetics) an organism having two different alleles of a particular gene and so giving rise to varying offspring.

codominance and multiple alleles
Homologous chromosomes are similar in terms of size, shape, and genes, but they are not similar in terms of the specific alleles they carry. Each homologous chromosome may carry different alleles for the same gene, leading to genetic diversity.

The allele that is expressed in an individual is referred to as the dominant allele. This allele masks the effect of the recessive allele when present.
In terms of a population, evolution is just the change of allele frequencies over time. Natural selection can cause certain advantageous alleles to increase in frequency, and detrimental alleles to decrease in frequency.
Alleles are different forms of a gene that can be inherited from each parent, while genotype refers to the specific combination of alleles an individual has for a particular gene. In genetic inheritance, alleles determine the genotype of an individual, which in turn influences their traits and characteristics.
Any change over time in the relative frequency of alleles in a population.
