6, considering four gene loci, what is the probability that an individual with the genotype AaBbccDd will produce a gamete that has the genotype ABCD? a, 1/4 c, 1/8 7. Consider a tetrahybrid cross (AaBbccDd x AaBbccDd), what is the probability that offspring will be homozygous dominant for all four traits (AABBccDD? a, 1/4 d. 1/128 e. 1/256 s, a is test ssed to a homozygous recessive individual, what is the probability that a phenotypically recessive individual offspring will be produced? 9. In couch potato fleas, pink eyes are dominant to blue eyes and straight wings are dominant to curly. A cross between a homozygous pink eyed, straight wing female is mated with a blue eyed, curly winged male. The Fr progeny are then crossed to produce the Fi generation. What is the probability of producing a blue eyed, curly winged flea in generation? d. 1/16 e. 1/32 b, 1/2 c. 1/8

Explanation / Answer

Question: 6. Considering four gene loci, what is the probability that an individual with the genotype AaBbCcDd will produce a gamete that has the genotype A B C D?

Answer: d. 1/16

No. of gametes will be = 24 = 16

Therefore, genotype of gametes will be 1/16.
