Genetics AIPMT

Hello sir I am doing preparation for All India Pre-Medical / Pre-Dental Entrance Test (AIPMT) so would you please provide me Important Concepts of Genetics???

[Kiran Chandar]

All India Pre-Medical / Pre-Dental Entrance Test (AIPMT) is conducted by the Central Board of Secondary Education (CBSE), Delhi for admission into MBBS and BDS courses in several medical colleges around the country.

Important Concepts in Genetics:
Most Important Concepts
Mendel's Laws of Inheritance
Dominance and Pleiotropy
Chromosome Theory of Inheritance

Important Concepts
Linkage and Crossing Over
Sex-linked Inheritance
Pedigree Analysis
Genetic Disorders in Human Beings

Not So Important Concepts
Introduction to Genetics
Complementary Genes

Question paper of Genetics of AIPMT

1. The contrasting pairs of factors in Mendelian crosses are called
alloloci
multiple allele
alleleomorphs
paramorphs

2. An organism with two identical alleles is
dominant
hybrid
heterozygous
homozygous

3. The allele which is unable to express its effect in the presence of another is called
codominant
recessive
supplementary
complementary

4. A dihybrid condition is
dominance
segregation
polygenic innheritance
independent assortment

5. According to Mendelism which character shows dominance?
wrinkled seeds
green pod colour
green colour in seed coat
terminal position of flower

6. When a single gene influences more than on trait it is called
epistasis
pleiotrophy
pseudodominance
none of these

7. Phenotype of an organism is the result of
genotype and environment iteractions
mutations and linkages
cytoplasmic effects and nutrition
environmental changes and sexual dimorphism

8. Text cross involves
crossing between two genotypes with dominant trait
crossing between two genotypes with recessive trit
crossing the F1 hybrid with a double recessive genotype
crossing between two F1 hybrids

9. Two crosses between the same pair of genotypes or phenotypes in which the sources of the gametes are reversed in one cross, is known as
test cross
dihybrid cross
reciprocal cross
reversal cross

10. When dominant and recessive alleles express itself together it is called?
dominance
pseudo dominance
co dominance
amphidominance

Hello sir, I’m preparing for the AIPMT entrance exam. In this exam one of the subjects is Biology. In the biology subject its one of the topic covered in AIPMT is Genetics. I want study material of Genetics of AIPMT?

[Kiran Chandar]

Genetics is the 2nd chapter of biology subject in AIPMT entrance exam:

AIPMT Botany Notes: Genetics:

Mendel's laws of genetics:
His laws include the following: Mendel's law of dominance: When an organism has two different alleles for a trait, one allele dominates.

Mendel's law of segregation: During gamete formation by a diploid organism, the pair of alleles for a particular trait separate, or segregate, during the formation of gametes (as in meiosis).

Mendel's law of independent assortment: The members of a gene pair separate from one another independent of the members of other gene pairs (These separations occur in the formation of gametes during meiosis.).

Genetics and Evolution

Herdity and variation : Mendelian Inheritance; Deviations from Mendelism – Incomplete dominance, Co – dominance, Multiple alleles and Inheritance of blood groups, Pleiotropy; Elementary idea of polygenic inheritance; Chromosome theory of inheritance; Chromosomes and genes; Sex determination – In humans, birds, honey bee; Linkage and crossing over; Sex linked inheritance – Haemophilia, Colour blindness; Mendelian disorders in humans – Thalassemia; Chromosomal disorders in humans; Down’s syndrome, Turner’s and Klinefelter’s syndromes.

Molecular basis of Inheritance : Search for genetic material and DNA as genetic material; Structure of DNA and RNA; DNA packaging; DNA replication; Central dogma; Transcription, genetic code, translation; Gene expression and regulation – Lac
Operon; Genome and human genome project; DNA finger printing.


Evolution : Origin of life; Biological evolution and evidences for biological evolution from Paleontology, comparative anatomy, embryology and molecular evidence; Darwin’s contribution, Modern Synthetic theory of Evolution; Mechanism of evolution – Variation ( Mutation and Recombination ) and Natural Selection with examples, types of natural selection; Gene flow and genetic drift; Hardy – Weinberg’s principle; Adaptive Radiation; Human evolution.
