How might stem cell research change the future of organ transplantation?

A. Stem cells could be designed to duplicate the patient’s immune system, making immunosuppressant drugs unnecessary.

B. Autoimmune diseases could be cured using stem cells, making organ transplantation unnecessary.

C. Stem cells could be used to manufacture a new class of drugs, making immunosuppressant drugs unnecessary.

D. Custom-made organs could be grown in a lab using the patient’s own stem cells, making organ transplantation unnecessary.

All individuals have two alleles for a given trait. according to mendel's these alleles are passed down one each from both mother and father.

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.

Is genetic diversity the same as genetic variation?
