Linkage: Consider three genes, each with two alleles. An individual with genotype AAbbDD is crossed with an individual whose genotype is aaBBdd. What are all the gamete types (gamete genotypes) that their offspring (AaBbDd) can produce? Draw chromosome diagrams if it helps you to answer the question. a. If the three genes are unlinked? b. If all three links are tightly linked (no crossing over)? c. If the first two genes are tightly linked (no crossing over), but the third...

In this tutorial you will examine dihybrid crosses: crosses
where alleles at separate loci assort independently into gametes at
meiosis. You will also use logic to determine unknown genotypes,
phenotypes, and genetic ratios from given data.
Part A - Deducing phenotypes and genotypes of selfed parents
Mendel studied pea plants dihybrid for seed shape (round versus
wrinkled) and seed color (yellow versus green). Recall that
the round allele (R) is dominant to the wrinkled allele
(r) and
the yellow allele...

Genes W, Y, Z assort independently and are dominant over their corresponding alleles w, y, z. You conduct an experiment where you set up a cross between two individuals heterozygous for each trait [Ww Yy Zz x Ww Yy Zz]. (a) What is the frequency of offspring resulting from the cross who are dominant homozygous--that is, whose genotype is [WW YY ZZ]?(b) What is the frequency of offspring whose phenotype is dominant for all three traits?

44. In Nicotiana tabacum, there are two independently-assorting gene loci that influence the appearance of the yellow burley character, i.e. A and B. When both loci are homozygous for their recessive alleles, i.e. aabb, the plant is yellow. When a dominant allele, i.e. A or B, is present at either locus, the plant is green. (a) If a cross were made between a homozygous green strain monosomic for one of these chromosomes (ABB) and a disomic yellow strain (aabb), what...
