Assume that D, E, F, G, H, and I are autosomal genes on different chromosomes. From the mating DdeeFfGGHhIi x DdEEFFGgHhii - calculate the probabilities of the following: For each - write your answers as a reduced fraction e. g. 1/16. What is the probability that one of the offspring will have the genotype DdEeFFGghhIi? What is the probability that one of the offspring will be heterozygous for each allele? What is the probability that one of the offspring will have the genotype DDEEFfGGhhii?

Refer to this portion of a dichotomous key for fish identification to answer the question. 1. (a) has a single dorsal fin ® 5 (b) has a double dorsal fin ® 2 2. (a) one fin is spiny, the other is smooth ® 3 (b) one fin is not spiny or smooth ® 4 5. (a) has small fin on back near tail ® 6 (b) has no fin on back near tail ® 7 6. (a) has barbs near the mouth ® catfish (b) does not have barbs near the mouth ® 10 7. (a) tail is asymmetrical ® 8 (b) tail is symmetrical ® 9 10. (a) scales are small ® trout (b) scales are large ® whitefish what is the next step to complete to identify a fish that has a single dorsal fin, no fin on the back near the tail, and no barbs near the mouth? step 2 step 5 step 7 step 10
