Important Questions on Principles of Inheritance and Variation
Assertion : Clones are produced by sexual reproduction and same sexual process.
Reason : These are prepared by group of cells descended from many cells or by inbreeding of a heterozygous line.
Assertion : Hybrids are generally back crossed.
Reason : Back cross is done to increase the traits of the parent.
Assertion : A gene may have several allelomorphs.
Reason : Wild form can mutate in more than one ways.
Reason: Genotype is the type of hereditary properties of an organism.
Assertion: Holandric genes are found on chromosome.
Reason : Inheritance of Holandric genes are always from father to son.
Assertion : Haploids are used to study mutation.
Reason : Most of the mutations are recessive.
Assertion : The shape of chromosomes is based on the position of centromere.
Reason : During anaphase, the chromosome bends in the region of centromere.
Assertion : Heterochromatin is genetically inactive.
Reason : It lacks genes.
