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?
A pink flowered Snapdragon plant was crossed with a red flowered Snapdragon plant. What type of phenotype/s is/are expected in the progeny?
In a plant, black seed color (BB/Bb) is dominant over white seed color (bb). In order to find out the genotype of the black seed plant, with which of the following genotype will you cross it?
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:
