Make sure to add one di-hybrid problem as a reply. Make sure to include the following: In a type of fish scales can be rounded or pointed at one end. The same scales can either have a smooth or rough texture. In this species of fish rounded smooth scales are dominant. What would be the phenotyoic ratio produced from breeding a fish with the pointed rough scales to a fish that had a heterozygous genotype for both characteristics? What % of the fish would be heterozygous for the texture characteristic?

In a species of donkeys there is different lengths of ears and different color of fur. There is long and short ears, and brown and black fur. Long ears and brown fur is dominant.

In a type of bat, there is 3mm teeth and 2mm teeth. 3mm teeth is dominant. They also have 24cm wingspan and 20cm wingspan.20cm wingspan is dominant. What would happen if you crossed a female with homozygous recessive for tooth length, and heterozygous for wingspan with a male that is heterozygous for tooth length, and homozygous dominant for wingspan.? What percentage will have the same phenotype as the father?

In a species of ducks short feathers are dominant to long feathers. Yellow is also dominant to brown in the same feathers. What percentage of the offspring would have the same genotype as their father if a homozygous dominant (for both traits) male and a heterozygous (for both traits) female were crossed?
