Sucess of mendal is
  • Selection of Peaplant
  • Studied of free characters
  • More Characters selection
  • Pea is Bisexual
Loss of Melanin pigment cause for:
  • Colourblindness
  • Depigmentation
  • Phenyl Ketoneuria
  • Alkaptoneuria
Gunetical identification of male human is:
  • By Nucleus
  • By cells
  • By Autosome
  • By Sex-chromosome
Rh
  • rr
  • TT
  • Rr
  • Both (a) and (c)
Cause of chromosomal mutation:
  • Euploidy
  • Polyploidy
  • Physical effect
  • All of these
Mendal was born in:
  • 17th century
  • 18th century
  • 19th century
  • 8th century
Two genes very close on a chromosome will show:
  • No crossing over
  • High crossing over
  • Hardly an crossing over
  • Only double crossing overy
First geneticist/father of genetics was:
  • de Vries
  • Mendel
  • Darwin
  • Morgan
An lndividual with into identical alleles is:
  • Hybrid
  • Dominant
  • Homozygous
  • Heterozygous
Mendal’s law can be applicable only when:
  • Characters are linked
  • Parents are pore breed
  • F
  • Onepair of contiasting characters depends on another pair
A true hybrid condition is:
  • tt Rr
  • Tt rr
  • tt rr
  • Tt Rr
The allele which is unable to express its effect in the presence of another is called :
  • Co-dominant
  • Supplementary
  • Complementary
  • Recessive
Most of the mutations are:
  • Recessive
  • Harmful
  • Germinal
  • All of these
Smallest segment of genetic material affected by mutation is :
  • Recon
  • Cistron
  • Muton
  • Exon
Genes located on V-chroinosome are:
  • Mutant genes
  • Autosomal genes
  • Holandric genes
  • Sex-linked genes
A strong mutagen is:
  • Cold
  • Heat
  • Water
  • X-rays
A point mutation is:
  • Thalassemia
  • Sickel-cell anaemia
  • Down’s syndrome
  • Nightblindness
Mendel’s second law is of the law of:
  • Segregation
  • Dominance
  • Polygenic inheritance
  • Independent assortment
An organism with two unlike genes of a trait is called :
  • Homozygous
  • Hetrozygous
  • Both of these
  • None of these
Mendel’s laws were discovered by:
  • Correns
  • Shermak
  • de meris
  • All of these
