Pleiotropy
BIOXII05: PRINCIPLES OF INHERITANCE AND VARIATION

342600 A pleiotropic gene

1 Controls a trait only in combination with another gene
2 Is expressed only in primitive plants
3 Controls multiple traits in an individual
4 Is a gene evolved during Pliocene.
BIOXII05: PRINCIPLES OF INHERITANCE AND VARIATION

342601 The phenomenon of pleiotropism refers to

1 Presence of several alleles of a single gene controlling a single crossover
2 Presence of two alleles, each of the two genes controlling a single trait
3 A single gene affecting multiple
phenotypic expression
4 More than two genes affecting a single
character
BIOXII05: PRINCIPLES OF INHERITANCE AND VARIATION

342602 What concept do the following sentences explain?
i. The effect of the gene is on metabolic pathways which contribute towards different phenotypes
ii. Phenylketonuria and sickle cell anaemia
are examples of this type of inheritance
iii. Starch synthesis in pea seeds is also an example

1 Polygenetic inheritance
2 Pleiotropy
3 Multiple alleles
4 Co - dominance
BIOXII05: PRINCIPLES OF INHERITANCE AND VARIATION

342603 Occasionally a single gene may express more than one effect, this is

1 Polygenetic inheritance
2 Pleiotropy
3 Multiple alleles
4 Co - dominance
BIOXII05: PRINCIPLES OF INHERITANCE AND VARIATION

342604 Find the correct statement
I. Generally a gene regulates a trait, but sometimes one has effect on multiple traits
II. The trait AB – blood group of man is regulated by one dominant allele and another recessive allele. Hence it is co – dominant.

1 Statement II is correct
2 Both statements I and II are correct
3 Both the statements are wrong
4 Statement I is correct
