Question
Assume that there is complete dominance and completepenetrance at each locus and that epistasis does not occur. (Theseare the same conditions we used in class). Write your answers innumeric form (not in words). Referring to the cross DdFFGghhRrTt xDDffGgHhRRTt:How many different gametes does the DdFFGghhRrTt parent produce?1
How many different genotypes are found among the progeny of thiscross? 2
How many different phenotypes are found among the progeny of thiscross? 3
What is the probability that the first offspring from this crosswill show the dominant phenotype for all loci? (Type in as adecimal and round to 6 digits.) 4
What is the probability that the first offspring from this crosswill be heterozygous for all loci? (Type in as a decimal and roundto 6 decimal digits). 5
What is the probability that the first offspring from this crosswill be a son with genotype DDFfGghhRrTt? (Type in as a decimal andround to 6 decimal digits). There are two that are wrong and I'm not sure but I think theyare 4 and 5 Assume that there is complete dominance and completepenetrance at each locus and that epistasis does not occur.

Explanation / Answer
What is the probability that the first offspring from this crosswill be heterozygous for all loci? (Type in as a decimal and roundto 6 decimal digits). answer answer : 128(3.125%) What is the probability that the first offspring from this crosswill be a son with genotype DDFfGghhRrTt? (Type in as a decimal andround to 6 decimal digits). answer 128(3.125%)
