Which one of the following best describe polygenic inheritance?
In polygenic inheritance, several sets of alleles may produce cumulative effect on the same character, i.e., human height and colour of skin and eye.
ABO group in human is an example of codominance, whereas flower colour of 4 O' clock plant is an example of incomplete dominance.
Hair pigmental mouse is an example of recessive epistasis, Sickle-cell anaemia is an example of codominance.
Match column I with column II and select the correct option from the given codes. Column I Column II A. Multiple alleles (i) Phenylketonuria in Humans B. Polygenes (Multiple genes) (ii) Blood groups in humans C. Pleiotropic (iii) Skin color in humans
Number of genotypes produced when individuals of genotype 'YyRrTt' are crossed with each other is
Which pair of features represents polygenic inheritance?
How many types of gametes are expected from the organism with genotype AABBCC?
When AABBcc is crossed with AaBbCc then the ratio of hybrid for all the three genes is
A dihybrid ratio of 1 : 4 : 6 : 4 : 1 is obtained instead of 9 : 3 : 3 : 1. This is an example of
An example of the quantitative trait in man is
Polygenic inheritance was first noted by
A polygenic inherited trait is controlled by three pairs of genes. Two individuals which are heterozygous for three alleles, are crossed with each other. What will be the phenotypic ratio of offspring?
In a plant, three dominant independently assorting genes A, B and C are essential for production of purple pigment. If any of the genes or all three genes are present in recessive condition then flower is colourless. Raw material $$\overset { A }{ \rightarrow} X \overset { B }{ \rightarrow} Y \overset { C }{ \rightarrow} Z$$ pigment A purple plant with genotype AABBCC cossed with a clourless plant with genotype aabbcc gives purple $$F_1$$ hybrid. On selfing of $$F_1$$, what will be the proportion of coloured offspring in $$F_2$$?
