Answer:
6. Polygenic inheritance
7. Co-dominance
8. Multiple allele
9. Incomplete dominance
Explanation:
This question depicts non-mendelian inheritance patterns i.e. inheritance that do not conform to Mendel's principle of inheritance. They are as follows:
6. POLYGENIC INHERITANCE is a type of inheritance in which multiple genes i.e. more than one gene, interact to determine the phenotype of an organism.
7. CO-DOMINANCE is a type of inheritance pattern in which two alleles of a gene are dominant, resulting in offspring that show both phenotypes. Example is blood group A and B in humans.
8. MULTIPLE ALLELISM is an inheritance pattern involving one gene having several different forms (alleles), resulting in more than two phenotypes. Example is the blood type in humans.
9. INCOMPLETE DOMINANCE is a type of inheritance in which two alleles of a gene are neither completely dominant nor completely recessive, resulting in a phenotype that is a combination of the two. Example is ROAN color in cattle
