In the tomato, red fruit (R) is completely dominant over green fruit (r) and yellow flowers (W) are completely dominant over white flowers (w). A cross is made between two true breeding plants, one has red fruit and yellow flowers and the other has green fruit and white flowers. The F1 generation has red fruit and yellow flowers. These F1 plants are test crossed to plants with green fruit and white flowers. The following results are obtained:
333 red fruit, yellow flowers
64 red fruit, white flowers
58 yellow fruit, yellow flowers
345 yellow fruit, white flowers
Total of 800
Required:

One of the newest applications of cell technology is called cybrid embryos. this process involves replacing the nuclear material of an animal cell with human nuclear material. how might this process affect public policies about research by using stem cells? the same policies and concerns about the use of human embryonic stem cells would most likely apply. the embryos would most likely be treated like traditional animal embryos and regulated accordingly. the process of forming cybrid embryos would most likely be banned by government regulators. the embryos would be treated as regular cells because they are not fully human in origin.
