How do genetics represent h dominant and Recessive allele?

A dominant genotype is represented as DD or Dd but with many different letters. The DD is a homozygous dominant, while the Dd is the heterozygous dominant. Recessive is always represented as dd or rr or whatever letter you want to use. It is always homozygous recessive. There can never be a heterozygous recessive.


What are the three different combinations of alleles?

If the gene for a trait has two alleles, one dominant (D) and one recessive (d) there are three possible combinations in the genotype: DD (homozygous dominant) Dd (heterozygous) dd (homozygous recessive)


What type of reaction is characterized by a release of energy?

The general term for a chemical reaction that releases heat is an exothermic reaction. The energy released is called enthalpy.A reaction that releases energy is called an exothermic reaction.


If a dog's genotype is Dd if it has a disease what genotype does another mate have to have in order for have of the puppies to not have a disease?

There is not really enough information in the question to answer it properly. You would need to know what trait the D and d stood for to give a proper answer.If the dog's genotype is Dd and it has the disease, this suggests that the disease is caused by a dominant allele. A healthy bitch would have the genotype dd and half of her pups would have the disease. There is no mate which would produce all heathly pups.If the dog is symptom free then the disease is caused by a recessive allele. In which case the dog should be matted with a dog with the genotype DD to have 100% symptom free pups. Mating Dd to Dd would give 75% symptom free pups and 25% sufferers. Mating the Dd dog to a dd dog would give 50% disease free pups and 50% sufferers.
