Correct Answer: D
Solution :
[d] Incomplete dominance (discovered by Correns) is the phenomenon where the dominant allele does not completely express itself. The inheritance of flower colour in Antirrhinum sp. is a good example of incomplete dominance. Haemophilia is a sex linked recessive disease. It is a type of Mendelian disorder since its inheritance follows the principles of Mendelian genetics and can be traced in a family by pedigree analysis. Transforming principle was given by Griffith. Dihybrid cross is a cross when two allelic pair are used for crossing. Several dihybrid crosses were carried out in Drosophila to study genes that were sex linked.You need to login to perform this action.
