AP Biology Genetics Practice Problems 1. Both parents are heterozygous for Round faces (dominant over square) and Brown hair (dominant over blonde). What is the probability of the offspring having round faces and blonde hair? 2. If the genotype is YyRrDd, what is the probability that the offspring will be: a. YYRRDD _________________ b. YyRRDd __________________ c. yyRRdd ___________________ d. YyRrDD __________________ e. YyRrDd ___________________ 3. Assume that a cross was made between fruit flies of genotype AAbb and those of genotype aaBB. What is the probability that you will get AaBb for a genotype? 4. What is the probability that each of the following pairs of parents will produce the indicated offspring? a. AABBCC x aabbcc AaBbCc b. AABbCc x AaBbCc AAbbCC c. AaBbCc x AaBbCc AaBbCc d. aaBbCC x AABbcc AaBbCc 5. The genotype of F1 individuals in a tetrahybrid cross is AaBbCcDd. Assuming independent assortment of these four genes, what are the probabilities that F2 offspring would have the following genotypes? a. Aabbccdd b. AaBbCcDd c. AABBCCDD d. AaBbccDd e. AaBBCCdd 6. In pea plants, long stems are dominant to short stems, purple flowers are dominant to white, and round seeds are dominant to wrinkled. Each trait is determined by a single, different gene. A plant that is heterozygous at all these loci is self-crossed, and 2048 progeny are examined. How many of these plants would you expect to be long stemmed with purple flowers, producing wrinkled seeds?
