Expert Solution

ANS : SEXUAL REPRODUCTION AND MISTAKES WHILE DNA IS COPIED.

NEW TRAITS RESULTS IN THE EVOLUTION OF NEW VRIETEIES OR NEW STRAINS OF BACTERIA . NEW TRAITS APPEAR DUE TO THE CHANGE IN NUCLEOTIDES SEQUENCE OF AN ORGANISM .WHICH RESULTS IN CHANGE IN SOME OF ITS CHARACETRISTICS .

SEXUAL REPRODUCTION AND MISTAKES WHILE DNA IS COPIED CAN RESULT IN THE FORMATION OF NEW TRAITS.

SEXUAL REPRODUCTION INVOLVES THE COMBINATION OF TWO SETS OF CHROMOSOMES FROM TWO PARENTS. SINCE SEXUAL REPRODUCTION INVOLVES THE COMBINATION OF GENETIC INFORMATION FROM TWO DIFFERENT PARENTS WITH DIFFERENT GENOTYPES IT WILL RESULT IN THE APPEARANCE OF NEW TRAITS IN THE OFFSPRING.

DNA IS THE GENTIC MATERIAL WHICH CONTROLS THE CHRACTERISTICS OF AN ORGANISM .ANY CHANGE IN THE DNA CAN CHANGE THE CHARACTERISTICS OF AN ORGANISM. SO MISTAKES WHILE COPYING THE DNA CAN RESULT IN THE APPEARANCE OF NEW TRAITS OF BACTERIA.

CONJUGATION IS A METHOD OF SEXUAL REPRODUCTION IN BACTERIA .THERE ARE THREE METHODS OF SEXUAL REPRODUCTION IN BACTERIA . THEY ARE TRANSFORMATION , TRANSDUCTION , AND CONJUGATION.

CONJUGATION: IN THIS METHOD OF SEXUAL REPRODUCTION A GENETIC MATERIAL FROM A BACTERIA ALSO KNOWN AS DONOR BACTERIA OR MALE IS TRANSFERRED TO ANOTHER BACTERIA WHICH IS ALSO KNOWN AS REPIENT BACTERIA OR FEMALE BACTERIA. THE GENTIC MATERIAL IS TRANSFERRED THROUGHA SPECIAL STRUCTURE FORMED BETWEEN THE TWO BACTERIA KNOWN AS CONJUGATION PILUS.

Meiosis Essay Question: Three events in sexual reproduction contribute to genetic variation in a population: independent assortment, crossing over, and random fertilization. Explain how the three processes of sexual reproduction are advantageous to organisms and generate genetic variation within a population. - State which phase of meiosis is occurring during each of the three events. - Also, explain what is happing during these phases that results in the genetic diversity of offspring. - How is this advantageous to the population...
