DEFINITIONS
Someone with cells from more than one zygote in them.
human chimera
What do we call a mother who got cells from her fetus during pregnancy?
Fetal chimera
How are man-made chimeras created?
transplantation tissues or organs
This test uses specific enzymes to cut out specific genes, multiply those genes segments, and then run the gene segments through gel electrophoresis.
PCR (polymerase chain reaction)
Which of these is a lie?
Mrs. Winkler used to be a cabinet builder.
Mrs. Winkler has herded sheep on horseback.
Mrs. Winkler enjoys botany and is great with plants.
enjoys botany, good with plants
Someone who has non-human cells transplanted in them.
xenotransplant chimera
What do we call a baby who got maternal cells in when they were in utero?
Maternal chimera
What is one difficulty or increased risk that man-made chimeras face?
Risk of rejection or out-competition of transplanted cell line.
This procedure takes chromosomes from a cell and pairs them up to look at. This can be used to identify chromosomal differences between cells when looking for chimerism.
karyotyping
What fish breeds by obligate chimerism.
anglerfish
Someone with a very small amount of cells from someone else (<1%)
microchimera
What do we call it when one baby is born with the cells of their ghost twin or vanished twin in them?
fusion chimerism
Name a real life example of a way doctors create a xenotransplant.
Using gene-edited pigs to make heart valves for humans.
This test checks for proteins on the surface of red blood cells and can be used identify if blood cells are being made in bone marrow from different zygotes (with different genes).
Blood typing
What is Mrs. Winkler's younger sister's name who Mrs. Winkler believes is a fusion chimera?
Iris
Someone who is a chimera without having had a medical procedure that made it happen.
natural chimera
What do we call it when twins are born that exchanged cells in utero and contain cells from each other?
Twin chimerism
What procedure for infertility increases the chance of twin chimerism?
In vitro fertilization
This genetic test uses specially glowing nucleotide probes that combine with specific gene sequences in chromosomes of a cell, allowing for the identification of an individual donor cell in a background of recipient tissue.
Fluorescence in situ hybridization (FISH)
What band sings the Mr. Roboto song?
Styx
A test used to detect numerical and structural chromosomal abnormalities.
Karyotype
What are two physical traits that can be used to identify natural chimeras without doing genetic testing?
Different colored eyes and different skin tones on one person
What is the name of Han Solo's wookie friend/sidekick in Star Wars?
Chewbacca
