Both fish seen here are African zebra cichlids. They have two color alleles. The allele for blue coloration is while the gene for orange coloration is 0. A fish that has both types oralleles will be marbled orange and blue. This type of fish
is not shown in the picture. Suppose that a male with genotype BO mates with a female that is also BD. What
percentage of each PHENOTYPE will their offspring have?
A
25% blue; 50% marbled; 25% orange
B)
25% BB: 50% BB, 25% BB
50% blue; 50% orange
D
50% BB: 50% BO

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
