Question

How are dominance, codominance and incomplete dominance patterns of inheritance different from each other?

Answer 1

Answer:

Dominance – When two traits (character) of a species is crossed, resulting offspring in F1 generation displays character of any one parent then it called as dominance.

 

Co-dominance – When two traits (character) of a species crossed, resulting offspring in F1 generation display characters of parents then it is called as co-dominance. For example coat colour in cattle. If one with red coat (skin with red colour hair) is crossed with one having white coat then the F1 hybrid would have roan colour hair (.i.e. patches of both red and white colour hair on skin)

 

Incomplete dominance -  When two traits (character) of a species is crossed, resulting offspring in F1 generation don’t resemble either of parents so called as incomplete dominance. For example in snapdragon flower ,if a pure (homozygous) red coloured flower is crossed with pure (homozygous) white coloured flower then the F1 generation includes pink coloured flower (heterozygous) .
