For this exercise, use the set of cards provided at the very back of your lab manual. There are five pairs of cards in the set, distinguished by color (a pair of white cards, a pair of blue cards, a pair of yellow cards, etc.). Each color pair represents a section of DNA from a particular chromosome: Blue: Chromosome 4 Red: Chromosome 7 Yellow: Chromosome 10 Green: Chromosome 15 White: Chromosome 20 Within each color pair, one card is labeled "Parental" and the other is labeled "Recombinant." These cards represent some of the DNA an offspring may inherit. If an offspring inherits the parental version of a chromosome card, the DNA was NOT recombined and was transmitted in its original form. If an offspring inherits the recombinant version of a chromosome card, the DNA was recombined and was transmitted in its new form. Follow steps 1-6 outlined in your lab manual on pp. 46-47, and fill in the chart on p. 47 of your lab manual. Analyze your results by answering the questions in this exercise. Do all offspring from the same parents inherit the same versions of the available genetic material? Why or why not?

Bisphenol a (often called bpa) is a chemical found in products that people use every day, from water bottles to food containers to children's toys. unfortunately, bpa leaches out of its many products and makes its way into our bodies. what are the health effects of bpa exposure? ongoing research is finding that elevated exposure to bpa can affect a wide variety of developmental and physiological processes, but one of the first studies of bpa's health effects came about because of a simple mistake in the lab. at a laboratory at case western reserve university in 1998, geneticist patricia hunt was making a routine check of her female lab mice. as she extracted and examined developing eggs from the ovaries, she began to wonder what had gone wrong. she noticed that many of the eggs showed problems with their chromosomes, and some had irregular amounts of genetic material, which can lead to miscarriages and birth defects in mammals. she learned that a lab assistant had mistakenly washed the plastic mouse cages and water bottles with a harsh soap, releasing bpa from the plastic. knowing that bpa is an endocrine disruptor, a chemical that can enter organisms and mimic hormones, hunt set out to discover whether it had adversely affected her mice.
