The correct option is 4.
In biology a hybrid is an offspring of two animals or plants of different races, breeds, varieties, species, or genera.[1] Using genetics terminology, it may be defined as follows.[2]

In general usage, hybrid is synonymous with heterozygous: any offspring resulting from the breeding of two genetically distinct individuals
a genetic hybrid carries two different alleles of the same gene
a structural hybrid results from the fusion of gametes that have differing structure in at least one chromosome, as a result of structural abnormalities
a numerical hybrid results from the fusion of gametes having different haploid numbers of chromosomes
a permanent hybrid is a situation where only the heterozygous genotype occurs, because all homozygous combinations are lethal.
