What is a test cross?
Advertisements
Solution
- The cross between the F1 hybrid and the recessive parent is called the test cross.
- The crossing of an F11 progeny with a double (homozygous) recessive parental progeny is done in order to determine whether the progeny is homozygous or heterozygous for a character under consideration. This is called a test cross.
