ASEXUAL AND SEXUAL REPRODUCTION

 ASEXUAL REPRODUCTION-   

                                                INVOLVES A SINGLE PARENTS IT RESULT IN OFFSPRING THAT ARE GENETICALLY IDENTICAL TO EACH OTHER AND TO THE PARENT ALL PROKARYOTES AND SOME EUKARYOTES REPRODUCE THIS WAY.THERE ARE SEVERAL DIFFERENT METHODS OF ASEXUAL REPRODUCTION. THEY INCLUDE BINARY FISSION,FRAGMENTATION,BUDDING ETC.

 SEXUAL REPRODUCTION-  

                                            INVOLVES TWO PARENTS. PARENTS PRODUCTIVE REPRODUCTIVE CELL CALLED GAMETES. THAT UNITE TO FORM As offspring .gametes are haploid cells .this means THEY CONTAIN ONLY HALF THE NO OF CHROMOSOMES FOUND IN OTHER CELLS OF THE ORGANISMS. GAMETES ARE PRODUCED BY A TYPE OF CELL DIVISION CALLED MEIOSIS.THE PROCESS IN WHICH TWO GAMETES UNITE IS CALLED FERTILISATION .THE FERTILISED CELL THAT RESULTS IS REFERED TO AS A ZYGOTE. A ZYGOTE IS A DIPLOID CELL,WHICH MEANS THAT IT HAS TWICE THE NO OF CHROMOSOMES A GAMETES.

ASEXUAL VS SEXUAL- 

                                       CELL DIVISION IS HOW ORGANISMS GROW AND REPAIR THEMSELVES .IT IS ALSO HOW MANY ORGANISMS PRODUCE OFFSPRING. FOR MANY SINGLE CELLED ORG. REPRODUCTION IS A SIMILAR PROCESS .THE PARENTS CELL SIMPLY DIVIDES TO FORM TWO DAUGHTER CELLS THAT ARE IDENTICAL TO THE PARENT.IN MANY ORGANISM TWO PARENTS ARE INVOLVED ,AND THE OFFSPRING ARE NOT IDENTICAL TO THE PARENTS .IN FACT,EACH OFFSPRING ARE UNIQUE. THE CHILDREN RESEMBLE THEIR PARENTS BUT THEY ARE NOT IDENTICAL TO THEM .INSTEAD,EACH HAS A UNIQUE COMBINATION OF CHARACTERISTIC INHERITED FROM BOTH PARENTS.
