Why do dogs have most of the characteristics of their parents?

Sagot :

Why do dogs have most of the characteristics of their parents?

  • Alleles give variation in characteristics   Growing dog has two copies of each gene, one of  which he inherited from his mom and one from his dad.  These two genes may be  similar or may be slightly different.  Different versions of the same gene are called alleles, and may cause variation in  the protein produced, or where, when, and how much of the protein is produced.  These differences in how the protein is produced contribute to the unique physical characteristics  of each dog, and account for the differences between each dog and each race.

What controls characteristics?

  • How a dog looks and behaves is dictated by a combination of the world in  which it lives, the world in which it has grown up and the genetics thereof.  Environmental factors could include the diet of a dog, how much exercise it gets, or  the levels of hormones in the uterus in which it was raised as an embryo.  Genetics of a dog are decided before its birth and  are the only way to transfer characteristics from parent to child.  For instance, the coat of a dog may be influenced by what it eats, sunlight,time of year, how short it is trimmed,  etc., but none of these factors will affect the coat of the puppies that it will have in the future, while its genes will.
