  • Wrinkled green seeds
  • Wrinkled yellow seeds
  • Round green seeds
  • Round yellow seeds
The traits which are expressed in first filial (F1) generation are known as which traits.
  • inherited
  • dominant
  • recessive
  • acquired
The number of successful variations are maximized by the process of:
  • inheritance
  • sexual reproduction
  • mutation
  • evolution
Which of the following act as an information source for making proteins in a cell?
  • DNA
  • Lipids
  • RNA

  • DNA
A pea plant shows the genetic makeup TtRr. How will the plant appear externally?
  • Tall with wrinkled seeds
  • Dwarf with round seeds
  • Dwarf with wrinkled seeds
  • Tall with round seeds
The number of differences that appear in the new progeny in case of sexual reproduction is termed as?
  • inheritance
  • variation
  • heredity
  • evolution
If two pairs of characters are crossed in pea plants, then they show an independent inheritance because:
  • they are separate characters
  • they are present on separate chromosomes
  • reproduction is of asexual type
  • they are present on separate plants
The normal number of chromosomes in the progeny is maintained when the germ cells:
  • take all maternal and paternal chromosomes
  • divide by the process of mitosis
  • divide by mitosis and take all maternal and paternal chromosome
  • take one chromosome from each pair
