Genotypic and phenotypic ratio in monohybrid cross remains same in case of
sex linked genes
pseudoallelic genes
intermediate inheritance
dominant and recessive genes
Lack of independent assortment of two genes 'A' and 'B' in fruit fly - Drosophila is due to
repulsion
recombination
linkage
crossing over
Which of the following animals is mostly used in genetic experiments?
Butterfly
Fruit fly
Housefly
Dragon fly
How many pairs of contrasting characters in pea pod were chosen by Mendel?
3
5
7
9
The genotype of a plant showing the dominant phenotype can be determined by
test cross
dihybrid cross
pedigree analysis
back cross
Mendel was successful in discovering the principle of inheritance as
he took pea plants for his experiments
he did not encounter linkage between the genes for the characters he considered
he had an in-depth knowledge on hybridization
he was a famous mathematician
Alleles are
alternate forms of a gene
homologous chromosome
pair of sex chromosome
none of the above
Allelism refers to
genic interactions controlling a character
multiple genes controlling a character
expression of many characters by a single gene
alternative forms of a gene at a given locus
Inheritance of flower colour is an example of incomplete dominance, which is seen in
Antrirrhinum
Pisum
Solanum
Hibiscus
Mendel does not get linkage due to
dominance
independent assortment
segregation
genes on same chromosome
