(a) How does Mendel’s experiment show that traits may be dominant or recessive?
(b) How traits get expressed from parents to offsprings? Explain with an example.
(c) Why are traits acquired during the lifetime of an individual not inherited?
Answers
Explanation:
(a) Mendel in his experiment on the inheritance of traits selected and crossed tall pea plant with dwarf pea plant. The F1 progeny had Tt genotype but the plant was tall. This shows that ‘T’ is dominant trait whereas ‘t’ is recessive.
(b) Traits are passed through DNA. When an egg is fertilized with sperm, the resulting offspring takes 50 percent of its DNA from each parent. This resulting combination of two halves of DNA determines what specific traits the child will have.
(c) Only the traits which are passed through DNA of germ cells are inherited to the offsprings during sexual reproduction. On the other hand the traits acquired during lifetime do not pass on to the DNA of germ cells that’s why they cannot be inherited.
