Principles of Inheritance and Variation questions
1199 published questions with worked solutions.
- Mating of an organism to a double recessive in order to determine whether it is homozygous or heterozygous for a character under...
- In Mirabilis, a hybrid for red (RR) and white (rr) flower produces pink (Rr) flower. A plant with pink flower is crossed with...
- __A__ gene produces all gametes that are similar, while a __B__ produces two kinds of gametes each having one allele with equal...
- Law based on fact that the characters don't show any blending and both the characters are recovered as such in F_2-generation...
- Test cross is
- Mendel self-pollinated F_2-plant and found that __A__ plants continued to generate dwarf plant in __B__ and __C__ generations. He...
- Theoretically, in incomplete dominance one allele function as normal, while another allele may function as
- By seeing the ratio of F_1 and F_2-generation, Mendel proposed that something was stably passed down unchanged over successive...
- When alleles of two contrasting characters are present together, one of the character expresses itself during the cross while the...
- The Mendel crossed true breeding tall and dwarf plant varieties in his experiment. The tall character was dominant and recessive...
- Mendel's experiments were based on hybridization between two plants differing in
- Which of the following statement is/are correct regarding law of segregation?
- Mendel crossed tall and dwarf plant. In F_2-generation, both the tall and dwarf plants were produced. This shows
- Mendel found the phenotype of the F_1-heterozygote Tt was to be exactly like the __A__ parent in appearance. He proposed that in...
- In Mendl's experiments with garden pea, round seed shape (RR) was dominant over wrinkled seeds (rr) and yellow cotyledon (YY) was...
- The law of segregation of characters is also called the law of purity of gametes because
- Dihybrid ratio of test cross 1:1:1:1 proves that
- Mendel could not find linkage because
- Sex-linked chromosomes of man are
- Which one of the following pairs of features is a good example of polygenic inheritance?
