All the genes found in a breeding population at a given time are collectively termed as:

It is the genetic compliment for a particular trait in an individual:

Position of a gene on the chromosome is called its:

Organism of pure line is that which produces individuals of:

The organism chosen by G. Mendel to explain the laws of inheritance was:

All of the following are recessive phenotypes found in Mendelian experimental plant except:

In Mendel’s monohybrid cross, short stem trait becomes recessive in F1 generation. It will express in F2 generation only when/in:

Depict the genotypic ratio of the cross between ‘Tt × Tt’ plants:

Keeping in view the Mendel’s law of segregation, if tall plants were crossed with short heighted plants, then which of the following best describe the F1 progeny?

A test cross is best described by:

Mendel’s law of independent assortment is not obeyed by:

In Mendelian dihybrid cross, how many individuals are homozygous recessive for both traits in F2 generation?

It is the chance of an event to occur:

With a genotype AaBb, the fraction of gametes that will contain ‘ab’ alleles is:

Dominance is physiological effect of an allele over its partner allele occupying:

When two independent events are occurring simultaneously like in dihybrid cross, the ratio of each joint phenotypic combination can be obtained by:

Which of the following blood groups in humans is an example of co-dominance?

ABO blood groups in humans are best studied example of multiple allelism and are controlled by the polymorphic gene ‘I’, which has three alleles ‘IA’ , ‘IB’ and ‘i’. Since there are different alleles, six different genotypes are possible. How many phenotypes can occur?

How many alleles of ABO blood group are present in an individual?

During meiosis, crossing over occur between:

Crossing over is:

Crossing over in diploid organism is responsible for:

The phenotype dihybrid ratio in F2 generation is:

In humans, sex of an individual depends upon:

_____________ form one linkage group on human chromosome 11.

How many linkage groups are present in humans?

If male is an affected case of hypophosphatemic rickets and female is normal, then chances of this trait in their offspring will be as under:

After an injury, haemophiliac’s blood fails to clot properly because it may have:

Haemophilia ‘A’ occurs due to disturbance in ___________ while haemophilia ‘B’ occurs due to disturbance in ___________, respectively.

If a carrier woman for haemophilia is married to a normal man, then all of the following combinations can exist except:

Chances for a man to be affected by haemophilia ‘C’ is:

A boy receives his X-chromosome from:

_____________ may produce many different alleles of a gene.

The method for analyzing inheritance pattern of traits in human being is:

It is the product of evolution:

All of the following are related to evolution except:

It provides the raw material for organic evolution:

Diversity between living organisms is due to:

According to Lamarck, extension of neck in giraffe was a result of:

Darwin’s finches discovered from the Galapagos Island serve as a good example of:

Example of vestigial organs in the human body are:
