Question

Assume that there is complete dominance and complete penetrance ateach locus and that epistasis does not occur. Referring to thecross BBDdGghhRrtt x BbDdggHHRrTT:
How many different gametes does the BBDdGghhRrtt parent produce?
How many different genotypes are found among the progeny of thiscross?
How many different phenotypes are found among the progeny of thiscross?
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 5 digits.)
What is the probability that the first offspring from this crosswill be heterozygous for all loci? (Type in as a decimal and roundto 5 decimal digits).
What is the probability that the first offspring from this crosswill be genotype BbDDggGgRrTt? (Type in as a decimal and round to 5decimal digits).

Explanation / Answer

For the first question, the answer is eight. (BDGhRt, BdGhRt,BDghRt,BDGhrt, BdghRt, BDghrt, BdGhRt, Bdghrt).
