- It must be complete without any grammatical issues.
- Have at least one question with it.
- It must be original.
Make sure to add two di-hybrid problem as a replies. 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 phenotypic 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 an insect species, long wings is dominant to short wings (use W and w) and the blue color is dominant to white (B and b). What will be the phenotypic ratio of the offspring of a heterozygous male and a female with heterozygous wings and homozygous recessive color?

Looks good except you need to provide more information on the first problems 1st parent.

In giraffes, long necks are dominant to short necks and sports are dominant to stripes. What are the possible genotypes of the offspring if the mom is homozygous dominant for necks and homozygous recessive for fur and the dad is heterozygous for both traits?

In a breed of dog brown eyes are dominant to blue and pointed ears are dominant to floppy. If you breed two dogs that are heterozygous for both traits, what percent of the offspring will have brown eyes and pointed ears?

There are black with white and brown with white zebras. Black and white zebras are dominant to the brown and white zebra. They have either stripes or spots on them. Stripes are dominant to spots. What would be the phenotypic ratio if you crossed a female who is heterozygous for both traits to a male who is homozygous dominant for stripes and heterozygous for black and white skin.

You are going to have to correct the second problem. Its cross is needs to be fixed. The other problem looks good.

A special type of pig can have either straight or curly tails. It can also be pink or black. Curly tails and the color pink are dominant. If a pig who is heterozygous for both traits is crossed with a pig who is homozygous dominant for tails and homozygous recessive for color what would the phenotypic ratio be?

If short is dominant to tall, red roses are dominant to pink roses, what is the phenotypic ratio of the offspring when you cross a tall, pink rose with a homozygous dominant short, heterozygous red rose?
