(i) Give the phenotype of F1 progeny.
(ii) Give the phenotypes of F2 progeny produced upon by the self-pollination of F1 progeny.
(iii) Give the phenotypic ratio of F2 progeny.
(iv) Name and explain the law induced by Mendel on the basis of the above observation.
Which one of the following traits of garden pea studied by Mendel was a recessive feature?
______ pairs of contrasting traits were studied by Mendel in pea plant.
Which of the following are reasons for Mendel’s success?
- Usage of pure lines or pure breeding varieties
- Consideration of one character at a time
- Maintenance of statistical records of experiments
- Knowledge of linkage and incomplete dominance
If a cross between two individuals produces offspring with 50% dominant character (A) and 50% recessive character (a) then the Genotypes of parents are:
Mendel blended his knowledge of science and mathematics to keep count of the individuals exhibiting a particular trait in each generation. He observed a number of contrasting visible characters controlled in pea plants in a field. He conducted many experiments to arrive at the laws of inheritance.
- What do the F1 progeny of tall plants with round seeds and short plants with wrinkled seeds look like?
- Name the recessive traits in the above case.
- Mention the type of the new combinations of plants obtained in F2 progeny along with their ratio, if F1 progeny was allowed to self-pollinate.
OR
If 1600 plants were obtained in F2 progeny, write the number of plants having traits:
