A person having genotype IA IB would show the blood group as AB. This is because of:
Pleiotropy
Co-dominance
Segregation
Incomplete dominance
A cross between two tall plants resulted in offspring having few dwarf plants. What would be the genotypes of both the parents?
TT and Tt
Tt and Tt
TT and TT

In a dihybrid cross, if you get 9:3:3:1 ratio it denotes that:
The alleles of two genes are interacting with each other
It is a multigenic inheritance
It is a case of multiple allelism
The alleles of two genes are segregating independently.
Mendel’s Law of independent assortment holds good for genes situated on the:
non-homologous chromosomes
homologous chromosomes
extranuclear genetic element
same chromosome
It is said that Mendel proposed that the factor controlling any character is discrete and independent. This proposition was based on the:
results of Fs generation of a cross.
observations that the offspring of a cross made between the plants having two contrasting characters shows only one character without any blending.
self-pollination of F1 offsprings
cross-pollination of parental generations
Mother and father of a person with ‘O’ blood group have ‘A’ and ‘B’ blood group respectively. What would be the genotype of both mother and father?
Mother is homozygous for ‘A’ blood group and father is heterozygous for ‘B’
Mother is heterozygous for ‘A’ blood group and father is homozygous for ‘B’
Both mother and father are heterozygous for ‘A’ and ‘B’ blood group, respectively
Both mother and father are homozygous for ‘A’ and ‘B’ blood group, respectively
