ABC Model for Flower Development (arabidopsis thaliana)
The ABC model of flower development explains how three classes of homeotic genes—A, B, and C—interact to determine the identity of floral organs in four concentric whorls: sepals, petals, stamens, and carpels. Class A alone specifies...

Blood Type Problems
What will be the blood type of the probable progenies of blood type AB and blood type O parents? Let's solve this problem in the scenarios below: What will be the phenotype from a father with heterozygous type A, and a mother with...

Dihybrod cross Tricks
A dihybrid cross is a breeding experiment between P generation (parental generation) organisms that differ in two traits. The individuals in this type of cross are homozygous for a specific trait. Traits are characteristics that are...
