Explain mendel 's concept of heredity by giving three points?
Answers
Answer:
Mendel has given three laws of inheritance: (a) Law of Dominance (b) Law of Segregation and (c) Law of Independent Assortment. 2. ... from this he concluded that tallness is dominant over dwarfness and therefore hides its effect in F1 generation.
Answer:
Here is your answer-
Explanation:
(i) Mendel worked on pea plant (Pisum sativum) and discovered the fundamental
laws of inheritance. He found that traits (characteristics) are controlled by factors
(which are now called genes) and each factor (gene) come in pairs. These factors
(genes) are inherited as distinct units, one from each parent.
(ii) Mendel studied that genes segregate during the formation of gametes (sperms
in males and ova in females) and they again combine in the offspring (one from
each parent) and appear as dominant or recessive trait. This can be worked out
by making test cross.
(iii) Mendel proposed three laws, namely :
(a) Law of segregation : Each inherited trait is defined by a pair of gene.
Parental genes are randomly separated to the germ-cells so that germ contain
only one pair of gene.
(b) Law of independent assortment : Genes of different traits are sorted
separately from one another so that the inheritance of one trait is not
dependent on the inheritance of another.
(c) Law of dominance : An organism with alternate forms of a gene will express
the form that is dominant.
