Rules for Inheritance
Rules/ Mechanism of inheritance was given by Gregor Mendel after he conducted experiments on the pea plant
-
Monohybrid Cross
-
-
-
-
However when he self-crossed the offsprings (F2 Gen) he found that 3 of them were tall while one of them was dwarf
-
1 F2 plant was homozygous tall (TT), 2 were heterozygous tall (Tt) and one was pure dwarf (tt)
-
He concluded that in a hybrid organism, only one expressed itself
-
-
Dominant traits appear in pure or hybrid conditions while recessive traits appear only in pure conditions
Dihybrid Cross
-
-
On self pollination of round and yellow (RRYY) and wrinkled and green seeds (rryy) he found that all the offsprings (F1 Gen) were round and yellow (RrYy)
-
Phenotypically there were round and yellow; wrinkled and yellow; round and green; and wrinkled and green seeds in the ratio of 9:3:3:1
