Chapter 8 - Heredity

1 / 15

A homozygous dominant guinea pig with black fur is crossed with a homozygous guinea pig with white fur. The F1 generation is crossed with itself.

What percentage of F2 generation is expected to show a white fur coat?

2 / 15

If a round, green-seeded pea plant (RR yy) is crossed with a wrinkled, yellow-seeded pea plant, (rr YY) the seeds produced in the F1 generation are

3 / 15

If a tall pea plant is crossed with a pure dwarf pea plant then, what percentage of F1 and F2 generation respectively will be tall?

4 / 15

Which statement about the genotypes of organisms is correct?

5 / 15

Which of the following is heterozygous?

6 / 15

In cattle, having horns is a recessive trait (h) to not having horns (H). When cattle with horns are crossed with cattle that do not have horns, the number of offspring having horns was equal to those not having horns. Which of the following is MOST LIKELY to be true?

7 / 15

  • Assertion (A): Height in pea plants is controlled by the efficiency of enzymes and is thus genetically controlled.
  • Reason (R): Cellular DNA is the information source for making proteins in the cell.

8 / 15

  • Assertion: The probability of survival of an organism produced through sexual reproduction is more than that of an organism produced through asexual mode.
  • Reason: Variations provide advantages to individuals for survival.

9 / 15

A heterozygous red-eyed female Drosophila mated with a white-eyed male would produce _____.

10 / 15

A zygote that has an X-chromosome inherited from the father will develop into a _____.

13 / 15

A recessive homozygote is crossed with a heterozygote of the same gene. What will be the phenotype of the F1 generation?

14 / 15

Two pea plants one with round green seeds (RRyy) and another with wrinkled yellow (rrYY) seeds produce F1 progeny that have round, yellow (RrYy) seeds. When F1 plants are selfed, the F2 progeny will have a new combination of characters. Choose the new combination from the following.

  1. Round, yellow
  2. Round, green
  3. Wrinkled, yellow
  4. Wrinkled, green
