Dihybrid cross help?? Please!?

Posted on 2016-03-10 18:43:00 in Biology by SYMOND

A father is homozygous for bent finger and heterozygous for brown hair. A mother is heterozygous for bent finger and homozygous for blond hair. 

B= bent (dominant) 
b= straight (recessive) 
H= brown hair (dominant) 
h= blond hair (recessive) 

What is the dads genotype? 
What is the moms genotype? 
What is the dad's possible allele combination? 
What is the moms's possible combination? 

Do a 4x4 dihybrid cross. How many offspring out of 16 will be heterozygous for bent finger and homozygous for blond hair?
