Q. Dihybrid ratio of test cross 1 : 1 : 1 :1 proves that
A) $F_{1}$hybrid produces four different progenies
B) $F_{1}$ hybrid produces two different progenies
C) Parents produce two different progenies
D) None of the above
Explanation
Dihybrid cross is a cross involving two pairs of contrasting characters. A dihybrid test cross gives 1 : 1 : 1 : 1 ratio indicating that when $F_{1}$hybrid is crossed with recessive parent the two pairs of factors segregate and assorting independently and produce four type of progenies.
