Question

Expected ratio of the 4 diff phenotypes (in dihybrid cross) can differ from actual as;

Accepted Answer

fertallisation of gametes random, so skewed ratio in small samplesgenes studied both on same chromosome (linked genes), if no crossing over, alleles for both characteristics always inherited together (not inherited independently)
