Description : f we cross pure-bred tall (dominant) pea plant with pure-bred dwarf (recessive) pea plant we will get pea plants of F1 generation. If we now self-cross the pea plant of F2 generation, ... plants not found in F2 generation but appeared in F2 generation, mentioning the reason for the same. -Biology
Last Answer : Answer. (a) All plants of F1 generation will be tall plants. (b) 3:1 (c) Dwarf trait is recessive trait which was not expressed in the F1 generation, the recessive trait gets expressed in the F2 generation after self pollination.
Description : If a dwarf pea plant was treated with gibberellic acid, it became as tall, as tall pea plants. If these pea plants are crossed with pure tall pea plants, what will be the phenotypic ratio in F1 generation? ... (b) 50% tall and 50% dwarf plants (c) 75% tall and 25% dwarf plants (d) 100% tall plants
Last Answer : Ans. ((d))
Description : When white -flowered plant were crossed with pure red - flowered plants, the progeny were - (a) White flowered (b) Red flowered (c) Exhibiting 3:1 ratio of red to whiteflowered plants (d) Exhibiting 1:1 ratio of red to whiteflowered plants
Last Answer : Ans:(b)
Description : How did Mendel obtain pure or true breeding varieties of the contrasting forms of pea plants?
Last Answer : Mendel obtained pure or true breeding varieties of pea plants by allowing them to self pollinate for several generations.
Description : If two pure reflections about a line passing through the origin are appliedsuccessively the result is a.Pure rotation b.Quarter rotation c.Half rotation d.True reflection
Last Answer : a.Pure rotation

Last Answer : Ans. Johnson
Description : All the progeny obtained from a single plant by vegetative pro pa-gallon are called - (1) Clones (2) Pure line (3) Indred line (4) Pedigree line
Last Answer : (1) Clones Explanation: A clone is obtained by vegetative propagation of a single plant and it propagates vegetatively in successive generation. It offers excitation for exploiting desirable ... their original characteristics after many years of vegetative propagation i.e. they are stable.

Last Answer : A. A parallel LC circuit
Description : Pick out the wrong statement (A) Co-current absorbers are usually used, when the gas to be dissolved in the liquid is a pure substance (B) In case of gas absorption, HETP is ... reaction (D) In actual practice, absorption is an endothermic process, while stripping is an exothermic process
Last Answer : (D) In actual practice, absorption is an endothermic process, while stripping is an exothermic process
Description : Selection of homozygous plant is (a) pure line selection (b) mass selection (c) mixed selection (d) introduction
Last Answer : (a) pure line selection
