Inheritance and Variation of Traits

is a process of transmission of heritable traits from parents to their offsprings.

is the basis of heredity and by this process, traits are passed on from the parents to the offsprings. Continuity of the gene pool is maintained by the process of inheritance.

are the basic unit of inheritance and located on chromosomes.

• variation

exists among individuals of one species. Variation is due to crossing over, recombination, mutation and environmental effects on the expression of genes present on chromosomes.

what did Mendel use to create his experiments?

• beans

• corn

• rice

• peas

how did he choose the pease for his experiment?

• 14 true-breeding plants of pea having seven distinguishable characters, which have two opposite traits.

• 13 true-breeding plants of pea having eight distinguishable characters, which have four opposite traits.

• 10 true-breeding plants of pea having five distinguishable characters, which have two opposite traits.

• 14 true-breeding plants of pea having 10 distinguishable characters, which have one opposite traits.

how many laws of inheritance did he give based on his data and observations?

• 5

• 3

• 7

• 2

which of the following were his laws?

• law of dominance

• law of segregation of genes

• law of co-dominance

• law of independent assortment

It is to find out the genotype of the plant showing dominant trait, the given plant is crossed with the recessive homozygote.

• test cross

• dominance
