Which of the following BEST describes mitochondrial inheritance in humans? A. Mitochondria are inherited only from the mother. Sperm don't have mitochondria, only eggs do. B. Mitochondria are inherited only from the mother. Once the mitochondrion from the sperm enters the egg, it is inactivated. Only maternal mitochondria divide as the fertilized egg divides. C. Mitochondria are inherited only from the mother. Sperm mitochondria aren't contained in the head of the sperm, which is the only part that penetrates the egg. D. Mitochondria are inherited only from the father. Eggs don't have mitochondria, but sperm do. E. Mitochondria are inherited from both parents. Both eggs and sperm contain mitochondria, so every cell in a human body includes both paternal and maternal mitochondria.

Based on their location in the atmosphere, the layers are able to have their own special characteristics. for example, most weather occurs in the troposphere. what occurs in each of the other layers? (site 1)

In a hypothetical breed of dogs, coat color is controlled by two genes. there are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. consider the following crosses.cross 1: black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. f1 males and females are all black. when f1 are intercrossed, f2 males and females are black or brown.cross 2: black females from a lineage of all black dogs are crossed with tan males from a lineage where all males are tan and all females are cream. f1 males are black, f1 females are gray. when f1 are intercrossed, f2 males and females are black, brown, gray, or tan.cross 3: silver females from a lineage where all females are silver and all males are gray are crossed with brown males from a lineage of all brown dogs. f1 males and females are all gray. when f1 are intercrossed, f2 males are black, brown, gray, or tan, f2 females are cream, gray, silver, or tan.select the correct statements regarding the mode of inheritance of the coat color genes.a) both genes are x-linked.b) both genes are autosomal.c) one of the genes modifies the expression of the other gene.d) each gene has an additive effect on the intensity of coat color.e) each gene independently specifies three colors.f) one of the genes is autosomal, and the other is x-linked.
