In pea plants, the allele for purple flower color is dominant to the allele for white flower color. if you performed a test-cross to determine the genotype of a purple-flowered plant, what would you expect the phenotypic ratio of purple-flowered to white-flowered progeny to be if the plant is homozygous? what if the plant is heterozygous? (a) if the purple-flowered plant is homozygous, then the progeny would all have purple flowers; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1: 1 ratio.(b) if the purple-flowered plant is homozygous, than the progeny would all have white flowers; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1: 1 ratio.(c) if the purple-flowered plant is homozygous, than the progeny would have purple to white flowers in a 1: 3 ratio; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1: 1 ratio.(d) if the purple-flowered plant is homozygous, than the progeny would all have purple flowers; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 3: 1 ratio.(e) if the purple-flowered plant is homozygous, than the progeny would have purple to white flowers in a 1: 3 ratio; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1: 3 ratio.

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.
