A scientist developed a technique for breeding cattle using adult stem cells. The technique involves extracting adult stem cells from a select donor bull and reproducing the cells in a laboratory. The next step involves the transplantation of the donor bull’s adult stem cells into a recipient bull that is sterilized to ensure only the sperm of the donor bull are produced. This technique will help breeders who are always in short supply of select bulls for breeding. What is a disadvantage of this technique?
it is difficult to identify a select donor.
It is beneficial only in the case of cattle.
It will delay the availability of recipient bulls for breeding.
It will reduce the biodiversity of the species.

1. the passing of is the basis of heredity. 2. our encode the instructions that define our traits. 3. each of us has thousands of genes, which are made of and reside in our chromosomes. 4. in addition to our genes, the we live in also define our traits. 5. humans have two complete sets of chromosomes. 6. when parents conceive a child, each parent contributes set of chromosomes. 7. every child receives of its chromosomes from the mother and half from the father. 8. this transfer takes place at when the father’s sperm joins the mother’s egg. 9. while most cells in our bodies have two sets of chromosomes, or a total of egg and sperm each have chromosomes. 10. when egg and sperm unite they create a single cell called a 11. each parent contributes complete set of chromosomes to their child. 12. since the parents contribute the chromosomes to each new child, every child inherits a unique set of chromosomes. 13. as a result, every baby will have a combination of traits.
