Answer 24

see...u have 2 parents...right?
one has the genotype BB ie blue wings and the other has bb yellow wings...correct? this is given

Answer 25

so what u do while making a punnet square is...separate the 2 letters in a genotype, which forms alleles....so BB will be separated as B and B. then write 2 letters of 1 genotype at the top and then next 2 letters of second genotype at the left side the way i hv written. Now u fill in the squares the way i have shown. When u fill the squares thats when u make a cross.
