Answer: The correct answer is-
1) Incomplete dominance, 2) Multiple allele, 3) Co-dominance
Explanation-
1) Incomplete dominance is a pattern of inheritance where a blend of the parental phenotype is produced because the alleles inherited from parents are neither dominant nor recessive.
A straight hair man and a curly hair woman producing a wavy hair offspring is therefore incomplete dominance.
2) Multiple allele-
When a particular gene has more than two variant forms ( alleles), which are responsible for variable expressions, this is called multiple allelism.
Example- ABO blood group.
3) Co-dominance
When both the gene variant ( alleles) are equally expressed in the heterozygous genotype, it shows codominance.
Example- Red and white flowers producing offspring with red and white proportions.
