List-II 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 |
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 resulting in the gain or loss of chromosome is called polyploidy. |
Statement I: | When many alleles of single gene govern a character, it is called polygenic inheritance. |
Statement II: | In Polygenic inheritance, the effect of each allele is additive |
1. | Double homozygous |
2. | Double heterozygous |
3. | Homozygous for seed colour and heterozygous for flower colour. |
4. | Heterozygous for seed colour and homozygous for flower colour. |
