EXCEPTIONS TO MENDELIAN INHERITANCE

When F1 had a phenotype which don't resemble both parents it is termed as

• codominance

• incomplete dominance

• polygenic inheritance

• pleiotropism

Incomplete dominance is observed in

• Snapdragon

• Mirabilis

• Both

• None

Example which explains both codominance and multiple allelelism is

• eye colour

• hair colour

• skin colour

• blood group

Which characters of pea reflects that a gene represents more than one character

• tall and dwarf

• green and yellow seeds

• axial and terminal flowers

• synthesis of starch and smoothness of seeds

Single gene representing more than one character is

• pleiotropism

• multiple allelelism

• polygenic inheritance

• codominance

in case of incomplete dominance, monohybrid F1 ------------ is 1:2:1

• genotype

• phenotype

• both

• wrong option

Choose the odd one

• MN blood group

• ABO blood group

• colour of chicken feather

• coat colour of cattle

When a pink snapdragon is crossed to a white snapdragon, what is the probability of getting a red snapdragon

• 1

• 1/2

• 1/4

• none

In case of codominance, product is

• produced from both alleles

• produced from n alleles

• incompletely produced from both alleles

• none are functional

Human skin colour is an example of

• codominance

• incomplete dominance

• multiple alleles

• polygenic inheritance
