It was commonly understood in the past the dogs come from a lineage of wolves, but that isn't the case now. Scientists have found out that dogs and wolves come from a common ancestor about 9,000 to 36,000 years ago. This was done through extensive DNA analysis with samples that took into consideration the geographic locations of their origin and of modern isolation. This yielded a result that despite geographical difference, the dogs are more closely related than to wolves. It is now understood that the complication of the genetic relationship between the two was caused mainly by interbreeding during the course of time, but it isn't just that. Some other factors have come into play including the presence of humans.
Detached ear lobe allele is dominant over attached ear lobe allele
<u>Explanation:</u>
Mendel is the one who found the reason why an offspring has characteristics of the parent. He found that some traits were exhibited in an individual while the others were not. So he named the expressive allele as dominant trait and the one which in not expressive as recessive trait.
He formulated a set of hypothesis and experimented it on the pea plant to form the “Law of Inheritance”. In humans the detached ear lobe, blood groups all are examples of the law of dominance. Hence Mendelian traits are the physical characters that are passed on from one generation to the other
.
The conditions in which a female child will inherit the disease of hemophilia, is if both the father and the mother are infected. Another possibility is if the Mother is a carrier for the disease while the Father is the only one affected.
