Since each gene carried by a diploid has two copies of the two genotypes, if they carry the same two alleles of the same gene, such a diploid organism or cell is homozygous [1] .
Homozygotes do not separate individuals with different genetic factors due to selfing. Therefore, breeding materials are always homozygous, maintaining their traits unchanged. Heterozygotes can be obtained by selfing of heterozygotes.
Homozygotes are divided into two categories: dominant homozygotes and invisible homozygotes [1] .
Dominant homozygote refers to two individuals with identical dominant alleles on the homologous chromosome, all of which are represented by capital letters, such as AA and AABB. Stealth homozygote refers to two individuals with identical recessive alleles on the same chromosome, all of which are represented by lowercase letters, such as aa and aabb.
