What is the pattern of inheritance for polygenic trait?
Genes $R$ and $Y$ follow independent assortment. If RRYY produce round yellow seeds and rryy produce wrinkled green seeds, what will be the phenotypic ratio of the F2 generation?
When a tall pea plant with round seeds was selfed, it produced the progeny of : (a) Tall plants with round seeds and (b) Tall plants with wrinkled seeds. Identify the genotype of the parent plant.
Given below are two statements: Statement I: Failure of segregation of chromatids during cell cycle resulting in the gain or loss of whole set of chromosome in an organism is known as aneuploidy. Statement II: Failure of cytokinesis after anaphase stage of cell division results in the gain or loss of a chromosome is called polyploidy. In the light of the above statements, choose the correct answer from the options given below:
Match List-I with List-II: \begin{array}{llll} List-I & List-II \\Type of Inheritance & Example \\A.Incomplete dominance & I. Blood groups in human \\B.Co-dominance & II. Flower colour in Antirrhinum \\C.Pleiotropy & III. Skin colour in human \\D.Polygenic inheritance & IV.Phenylketonuria\end{array} Choose the correct answer from the options given below:
