In case of incomplete dominance, what will be the phenotypic ratio of F2 generation ?
3 : 1
1 : 2 : 1
1 : 1 : 1 : 1
2 : 2
Which of the following is best suited for codominance ?
Both are recessive
Both are dominance
One is recessive
One is dominance
Which of the following represent a test cross ?
Ww × WW
Ww × Ww
Ww × ww
WW × WW
Lack of independent assortment of two genes 'A' and 'B' in fruit fly Drosophila is due to
repulsion
recombination
linkage
crossing over
In garden pea , yellow colour of cotyledons is dominant over green and round shape of seed is dominant over wrinkled. When a plant with yellow and round seeds is crossed with a plant having yellow and wrinkled seeds, the progeny showed segregation for all the four characters. The probability of obtaining green round seeds in the progeny of this cross is .
1/4
1/8
1/16
3/16
Genes are made up of
histones
hydrocarbons
polynucleotides
lipoproteins
Some individuals with blood group A may inherit the genes for blond hair, while other individuals with blood group A may inherit the gene for brown hair. This can be best explained by the principle of
dominance
multiple alleles
independent assortment
incomplete dominance
