Document Summary

Chapter 14 - genetics - simple patterns of inheritance. Tall dad + short mom = medium height children. Their children would pass of the trait of medium height off to their. Estimating the distance between genes on a chromosome using crosses. Chance that an event will have particular outcome. P=# times event occurs/total # of poss. Pheads= 1 head/1 h +1 t = . Probability that 2 or more independent events will occur. Toss a coin what is the probability that you will get heads both times. Probability that one or two or more mutually exclusive outcomes will occur. Add the probabilities of the possible outcomes. Toss a coin - probability of heads or tails. 2 factor cross (seed color and seed shape) Each trait is determined by a single gene that has 2 alleles. Some offspring will show new trait combos. F1 produces a variety of gametes, not just yr and yr.
