DNA polymerase adds nucleotides to the growing DNA strand, whereas DNA ligase joins the breaks in DNA having matching ends during replication,... View Article
The DNA ligase joins the two complementary DNA strands. It catalyses the formation of a phosphodiester bond. DNA ligase is used in DNA repair,... View Article
In the F2 generation of the dihybrid cross, we get 4 dihybrid plants having genotype RrYy, when we cross RRYY (round yellow) and rryy (wrinkled... View Article
The phenotype ratio of the dihybrid cross in the classic Mendel experiment is 9:3:3:1. Here the two allelic pairs assort independently into the... View Article
When parents with genotype RRYY (round yellow) and rryy (wrinkled green) are crossed, in the F1 generation we get all the heterozygous round and... View Article
The dihybrid test cross between the dihybrid F1 plants with the homozygous recessive parent yields the ratio of 1:1:1:1. Further reading:... View Article
Dihybrid cross is done to study the inheritance pattern of two different allelic pairs and the relationships between them. Further reading:... View Article
In a monohybrid cross, only one pair of contrasting traits is considered, whereas in a dihybrid cross the inheritance pattern of two pairs of... View Article
When a mating experiment is done taking into consideration two pairs of contrasting traits in an organism, it is called a dihybrid cross. Here... View Article
