Last Answer : (3) Sexual reproduction Explanation: Genes located on different chromosomes will be inherited independently of each other. Mendel observed that, when peas with more than one trait were crossed, the progeny did not always match the parents.

Last Answer : Sexual reproduction

Description : Explain Mendel’s law of Independent Assortment.

Last Answer : Combinations of characters which are not present in the parental forms are produced in the next generation. When there are two pairs of contrasting characters, the distribution of the members of one pair into the gametes is independent of the distribution of the other pair.

Description : State Mendel’s law of Independent Assortment.

Last Answer : “Factors controlling separate characters normally move independent of each other during gamete formation.”

Description : Explain Mendel’s law of segregation.

Last Answer : The two pairs of factors separate during the formation of gametes. They do not blend but separate into different gametes. The gametes combine together by random fusion at the time of gamete formation.

Description : State Mendel’s law of segregation or law of purity of gametes.

Last Answer : “The pair of factors for a given character separates in equal ratio at the time of gamete formation during meiosis”.

Description : State Mendel’s principle of dominance.

Last Answer : “When two factors responsible for a pair of contrasting forms of a single character come together, normally one expresses itself, while the other does not”.

Last Answer : (c) independent assortment
