In pea, the gene that controls starch synthesis shows all of the following except

1.  Dominance 

2.  Incomplete dominance

3.  Multiple allelism

4.  Pleiotropy

  

What is incorrect for genetic maps?

1.  Alfred Sturtevant prepared it for the first time using monohybrid test cross

2.  It is a measure of the distance between genes present on the same chromosome

3.  Stronger the linkage lesser is the distance between two genes

4.  It was extensively used in the case of the Human Genome Sequencing Project

Match the column correctly

        Column l                            Column ll

a.  Phenylketonuria                  i. Autosomal trisomy associated with mongolism

b.  Down's syndrome               ii. Gynaecomastia

c.  Klinefelter's syndrome        iii. Autosomal recessive trait associated with mental retardation

d.  Turner's syndrome             iv.  Sterile females with rudimentary ovaries 

1.  a(iii), b(i), c(iv), d(ii)

2.  a(ii), b(iii), c(i), d(iv)

3.  a(ii), b(i), c(iii), d(iv)

4.  a(iii), b(i), c(ii), d(iv)

All are X-linked traits, except

1.  Colourblindness

2.  Haemophilia

3.  Deficiency of glucose-6-phosphate dehydrogenase

4.  Hypertrichosis

If we change the position of genes on chromosomes it will be included in

1.  Gene mutation

2.  Chromosomal mutation

3.  Polyploidy

4.  Transversion mutation

If size of strach grains in pea is considered as phenotype, Bb alleles show

1.  Dominance

2.  Codominance

3.  Incomplete dominance

4.  Pleiotropism 

Both the alleles produce their effect in

1.  Heterozygous B blood group

2.  Sickle cell hemoglobin

3.  Snapdragon flower color

4.  Cucurbits fruit color 

Law of segregation can be proved with

1.  The presence of dominant genotype in ${\mathrm{F}}_2$

2.  The presence of recessive genotype in ${\mathrm{F}}_1$

3.  The presence of recessive homozygous in ${\mathrm{F}}_2$

4.  The presence of a heterozygous individual in ${\mathrm{F}}_2$

Which of the following traits shows expression in only homozygous condition?

1.  Yellow seed

2.  Inflated pod

3.  Axial flower

4.  Wrinkled seed

In the given below figure what does (a) and (b) represent

1.  GAG, Glumatic acid

2.  GUG, Valine

3.  GAG, Valine

4.  GUG, Glumatic acid
