It is a basic idea of human biology, taught in grade schools everywhere: Identical twins come from the same fertilized egg and share identical genetic profiles. But according to new research, though identical twins share very similar genes, identical they are not. The discovery opens a new understanding of why two people who hail from the same embryo can differ in phenotype (physical characteristics), as biologists refer to a person’s physical manifestation.
The new findings appear in the March issue of The American Journal of Human Genetics, in a study conducted by scientists at the University of Alabama at Birmingham and universities in Sweden and the Netherlands. The scientists examined the genes of 10 pairs of monozygotic, or identical, twins, including 9 pairs in which one twin showed signs of dementia or Parkinson’s disease and the other did not.
It has long been known that identical twins develop differences that result from the environment. And in recent years, it has also…

One of the earliest experimental embryology experiments was conducted by Wilhelm Roux, who used a hot needle to kill one of the cells in an amphibian embryo at the two-cell stage. In the experiment, the remaining living cell formed only half of an embryo. However, later vertebrate experiments showed that by completely separating cells in early embryos, each can make complete individuals. What could explain the discrepancy in these experiments?

Would you expect early or late stages to be modified the most? Why? The basic stages of embryological development are remarkably similar for a wide range of organisms. How would you explain such consistency? As cells invaginate and move about, do they “know” where they are? If not, how is movement controlled? If so, how do they perceive their position.

If so, how?arrow_forwardhttps://nj.pbslearningmedia.org/resource/tdc02.sci.life.stru.different/cell-differentiation/#.XhYcbf5KjBI How would you explain the similarities among bird, mammal, and reptile embryos at the early stages of development, and what directs the sequence of events during embryonic development?arrow_forward

- Cloning is the process of creating genetically identical organisms. One simple method of cloning is called artificial embryo twinning. In this process, an early stage embryo is separated into two groups of cells. Each group of cells is then allowed to develop. The embryos are then implanted into the surrogate mother. Each embryo is genetically identical to the other. Some pregnancies in humans have a similar result. Explain how identical twins are formed. Compare and contrast the natural formation of identical twins to the artificial embryo twinning process. Explain how the formation of identical twins or the process of artificial embryo twinning differs from the formation of fraternal twins.arrow_forwardA controversial issue, closely related to cloning, that has caused a lot of debate is the use of embryonic stem cells. One possible application of these cells is that they may be able to supply replacement tissues to treat diseases such as Parkinson's disease, diabetes, paralysis due to spinal cord injuries, and other degenerative diseases. The word "embryonic", has caused fierce opposition to this type of research because embryos are destroyed when the stem cells are removed. Questions that have surfaced in this debate include: When a cell nucleus is transferred to another cell, have we created life? Does a stem cell have the same status as a human? What should be done with the embryos that are leftover at in vitro fertilization (IVF), clinics? Advocates argue that the medical benefits of stem cell research would be enormous. Opponents argue that life begins at conception and thus this type of research is abortion.
