Question

mendel's principles of inheritance

Answer 1

inheritance is the transmission of genetically controlled characteristics from one generation to the next . in this case mental gives example of dihybrid cross in which the parent plants having the phenotype round yellow seeds have the factors of Inheritance of gene combination RRYY . On the other hand the parent plants having the phenotype wrinkled green seeds have the factors of Inheritance of gene combination rryy keeping these points in mind we cannot show the dihybrid cross by drawing a chart as we did in the case of monohybrid cross . The chart showing the dihybrid cross between pea plants having round yellow - seeds and wrinkled green seeds is given below

Answer 2

mendel's principle of inheritance are :-
1. law of dominance
a character that appear in F1 generation after monohybrid cross is considered as dominating character and this phenomenon is called law of dominance.
2. law of segregation
law of segregation state the two factors controlling One character segregate or separate from each other during the formation of gametes it also known as law of purity of gametes.
3. law of Independence assortment
it state that the factors or genes controlling different character assort independently without influencing Each Other during the formation of gametes.
