Consider the case of three independently assorting genes. Upper case letters represent dominant alleles, lower case letters represent recessive alleles. For the following cross: AAbbCcdd x AaBBCcDd a. How many different gamete genotypes can each parent produce? b. How many different offspring genotypes can these parents produce? c. What is the probability that an offspring will be heterozygous for all genes? d. What is the probability that an offspring will be homozygous dominant for all genes? e. What is the probability that an offspring will be homozygous recessive for all genes? f. What is the probability that an offspring will express all recessive phenotypes? g. What is the probability that an offspring will express all dominant phenotypes?

Let's say an individual has a genotype of AabbCcDdEeffGg. 5A) How many different kinds of gametes can the individual produce? 5B) If this individual is crossed with another individual with genotype aaBbCcddEeFfgg, what is the probability that they will have an offspring with a dominant phenotype across all of these genes?

Two organisms, AABBCCDDEE and aabbccddee, are mated to produce an F1 that is self-fertilized. If the capital letters represent dominant, independently assorting alleles:(a) How many different genotypes will occur in the F2?(b) What proportion of the F2 genotypes will be recessive for all five loci?(c) Would you change your answers to (a) and/or (b) if the initial cross occurred between AAbbCCddee x aaBBccDDEE parents? (d) Would you change your answers to (a) and/or (b) if the initial cross occurred between AABBCCDDEE x aabbccddEE parents?
