VARDHMAN ACADEMY, RADHA GARDEN, GANGANAGAR, MEERUT BIOLOGY REVISION – IV CH – PRINCIPLES OF INHERITANCE AND VARIATION 05 MARKS QUESTION Q1. A dihybrid heterozygous round, yellow seeded garden pea was crossed with a double recessive plant. a. What type of cross is this? b. Work out the genotype and phenotype of the progeny. c. What principle of Mendel is illustrated through the result of this cross? Q2. In dogs, barking trait is dominant over silent trait & erect ears are dominant over drooping ears. What is the expected phenotypic ratio of offspring when dogs heterozygous for both the traits are crossed? Q3. Differentiate between dominance, co-dominance & incomplete dominance with one example each. Q4. A dihybrid heterozygous tall & yellow pea plant was crossed with double recessive plant. a. What type of cross is this? b. Work out the genotype and phenotype of the progeny. c. What principle of Mendel is illustrated through the result of this cross?
