(Pollen grains from flowers of tall plants dusted over the stigma of short plants)Mendel’s Conclusion:The ‘dwarf’ trait was also carried, but remained hidden in F1 generation. This trait got expressed only in F2 generation.\xa0 | |

What is a sexual reproduction. |
|
Answer» Sexual reproduction is the type of reproduction which two different gametes meet and produce a new individual . This helps in variation Thank you so much maria anna alwin sexual reproduction involves two parents and gamete formation. Gametes are special cells which are formed after meiosis. There are two types of gametes, viz. male and female gametes. The number of chromosomes is haploid in the gametes. When gametes fuse during fertilization, the number of chromosomes becomes diploid. This is important for maintaining the unique identity of a particular species which reproduces by sexual method.In sexual reproduction, the offspring gets sets of genes from two different individuals. This leads to subtle variation through subsequent generations. These variations accumulate over thousand of generations and finally may give rise to a new species. That is how all complex organisms have evolved from a common ancestor. Sexual Reproduction. Mode of reproduction in which new individuals are formed from two parents. *** is involved (Fusion between male & female gametes give rise to the new organism) Plz pata do kal mera paper ja |

How mendel got pure bred of tall or dwarf pea plant? |
| Answer» Pure breeding plants contain similar alleles in a pair (homozygous condition) for a particular trait.On crossing pure breeding tall pea plant (TT) with pure breeding dwarf plant (tt).Dwarf plants were not found in F1 generation, but appeared in F2 generation. This occurred due to dominance of allele responsible for tallness (T) over recessive allele responsible for dwarfness (t) in a pea plant. The recessive alleles are expressed only in homozygous condition/similar alleles in pair (tt). The offspring obtained in F1 generation were all heterozygous (Tt), in that condition, dominant allele controlling the trait of tallness (T) overpowers the recessive allele(t). This is in | |

Short note on working on ac genrator |
| Answer» Working\tThe axle is rotated such that it moves in the clockwise directions that is AB moves up and CD moves down. \tAccording to Fleming\'s Right Hand rule, the induced current is setup in the coil along B1-> AB -> BC -> CD -> B2. This means that the external current flows from B2 to B1.\tAfter half a rotation, arm CD starts moves up and AB moves down.\tAccording to Fleming\'s Right Hand rule, the induced current is setup in the coil along B2-> AB -> BC -> CD -> B1. This means that the external current flows from B1 to B2.\tThus after every half rotation of the coil, the current changes direction. This is called an AC current. \tAC current(Alternating current) : Changes its direction after equal intervals of time. It is easier to transmit this current over long distances due to lesser loses and hence this is the current that is supplied to our houses from the electricity department. | |
