8888.	Question :Explain the inheritance of two genes' in pea plants with two suitable examples.
Answer» Solution :Schematic representation of dihybrid cross (two gene inheritance) Dihybrid Phenotypic ratio= ROUND yellow 9: Round green 3: Wrinkled yellow 3: Wrinkled green, i.e. 9:3:3:1 `P_1` F `F_2` checker board `F_2` Phenotypic ratio Detailed Answer: Inheritance of Two Genes Dihybrid Cross A cross between two PARENTS differing in two pairs of contrasting characters. Mendel made some dihybrid crosses e.g. Cross between pea plant with round shaped and yellow coloured SEEDS (RRYY) and wrinkled shaped and green coloured seeds (rryy). On observing the F, Mendel found that the yellow and green colour segregated in a 3:1 ratio. Round and wrinkled seed shape also seg regated in a 3:1 ratio. Thus, the segregation of one pair of contrasting characters (Round and wrinkled shape) is independent of the segregation of ANOTHER pair of contrasting character (yellow and green) colour and also that some new combinations of character appear in `F_2` generation as the alleles get randomly rearranged in the offsprings at the time of fertilization. Dihybrid genotypic ratio: 1:2:1:2:4:2: 1:2:1 RRYY = 1, RRYy = 2, RrYY = 2, RrYy = 4, RRyy = 1, Rryy = 2, rrYY = 1, rrYy = 2, rryy = 1

8889.	Question : Draw schematically the phosphorus cycle in nature and mention what type of nutrient cycle it is?
Answer» Solution :Phosphorus Cycle : The natural reservoir of phosphorus is rock which contains phosphorus in the form of phosphates. On weathering, minute amount of phosphates dissolve in soil solution and is absorbed by the roots of the plants. The waste products of dead organisms are DECOMPOSED by BACTERIA to RELEASE phosphorus. Gaseous EXCHANGE between organism and environment is negligible as compared to CARBON.
