how did mendal showed that traits exist Forever... either in dominant or recessive? ( karlo google : p )
Answers
Answer:
Mendel has shown that the traits whether dominant or recessive don't change
he has proved it by LAW OF SEGREGATION that means the the gametes/genes won't mix up with other gametes/genes even at the time of crosses.It shows the purity of gametes
This is a Universally accepted LAW.
hope it helped....
Step-by-step explanation:
Mendel conducted the experiments using Pisum sativum or pea plant.
He selected homozygous tall (TT) and dwarf (tt) pea plants.
He crossed the tall pea plant with the dwarf pea plant.
It was observed that the F_1
1
generation are all tall plants.
Thus, it was concluded that the gene causing tallness is dominant while the gene causing dwarfness is recessive.
The trait expressing itself in the hybrid is the dominant one.
This experiment proves Mendel’s first law of inheritance.
It states that when a pair of contrasting factors is brought in a hybrid, one factor inhibits the appearance of the other, one which inhibits is the dominant one and which is inhibited is recessive.
