The genetic constitution of an organism, is called its genotype.
A gene is a unit of inheritance, which contains information that is required to express a particular trait in an organism. An allele is one of the s...
Blending inheritance is the phenomenon in which the expression of a trait is due to mixing or blending of the parental characters and the trait expres...
The parental forms of the trait appear without any change in the F2 generation.
Seed shape: Round and wrinkled. Seed colour: Yellow and green.
Flower position: Axial flowers and terminal flowers. Flower colour: Violet flowers and white flowers.
(i) Pod colour: Green pods and yellow pods. (ii) Pod shape: Inflated pods and constricted pods.
Colour of the pod, shape of the pod, colour of the flower, position of the flower, shape of the seed.
A true-breeding line is one that has undergone continuous self-pollination/inbreeding and shows stable inheritance and expression of a trait for sever...
Genetics is the branch of science that deals with inheritance and variation of traits.
Inheritance is defined as the process by which characters are passed on from one generation to the next.
True, 9 : 3 : 3 : 1 is the genotypic ratio of a Mendelian dihybrid cross.
True, Mendel could not have framed the law of independent assortment, if the genes he had studied, showed linkage.
False, The cross between the F1hybrid with a homozygous dominant individual is called a test cross.
False, The phenotype of the F1 hybrid resembles the dominant parent when there is incomplete dominance.
True, The recessive trait appears only under homozygous condition.
