If red and white colour flowers in Mirabulus jalapa are crossed, the F1 generation will show……….
a) all red
b) all white
c) all pink
d) 75% red and 25 white
Explanation: it follows incomplete dominance principle
In which of the following dominance relation, both different alleles of a gene expressed in heterozygote condition?
a) complete dominance
b) incomplete dominance
c) Co-dominance
d) over dominance
Which of the following example shows Co-dominance?
a) height in garden pea
b) flower color in 4 O’clock plant
c) ABO blood group
d) drosophila eye pigment
What will be the phenotype of human blood group when true breeding A cross with true breeding B?
a) all the offspring will have A blood group
b) all the offspring will have B blood group
c) half will have A and half will have B blood group
d) all offspring will have AB blood group
Explanation: it is due to Co-dominance and both alleles express themselves in heterozygous condition
What will be the genotype of human blood group when true breeding A cross with true breeding B?
a) all the offspring will have AA
b) all the offspring will have BB
c) half will have AA and half will have BB
d) all offspring will have AB genotype
Explanation: it is due to Co-dominance and both alleles express themselves in heterozygous condition
When the phenotypic expression of heterozygotes become more intense than the homozygous state of the dominant allele, it is called……….
a) complete dominance
b) incomplete dominance
c) Co-dominance
d) over dominance
