When crossing white rabbits with shaggy hair and black rabbits with smooth hair, offspring was obtained: 50% black hairy and 50% black smooth. When crossing other pairs of white rabbits with furry hair and black rabbits with smooth hair, 50% of the offspring turned out to be black furry and 50% – white furry. Make a diagram of each cross. Identify the genotypes of parents and offspring. Explain what the law is in this case.
The scheme for solving the problem includes:
1) 1 crossing:
P rabbits: white furry aaBb x black smooth AAbb
G AB, AB AB
F1 50% black hairy Aabb, 50% black smooth Aabb;
2) 2 crossing:
P rabbits: white furry aaBB x black smooth Aabb
G AB AB, AB
F1 50% black hairy AaBb, 50% white hairy AaBb;
3) the law of independent inheritance of characters appears
