|
Polygenes are ____
|
|
Both alleles that give partial influence in heterozygous condition
|
|
|
Both alleles in a heterozygote are dominant and fully expressed in phenotype.
|
|
|
More than two alternative forms of a particular gene that occupy the same locus.
|
|
|
More than two genes occupy different locus but control the same characteristic.
|
Explanation:
Detailed explanation-1: -So, the correct option is ‘Multiple alleles’.
Detailed explanation-2: -Homologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci. One homologous chromosome is inherited from the organism’s mother; the other is inherited from the organism’s father.
Detailed explanation-3: -So, the correct option is ‘Alleles’.
Detailed explanation-4: -Gene located at the same locus but having different expression are: Multiple alleles.
