About 70% of Canadians get a bitter taste from the chemical phenyl thiocarbamide (PTC), while the other 30% do not. The ability to taste this chemical (T) is a dominant characteristic, while taste-blindness to it is recessive (t). Tongue-rolling ability is dominant (R), while the inability to roll the tongue is recessive (r). A tongue-rolling woman who is taste-blind for PTC has a father who could not roll his tongue but could taste the PTC chemical. She marries a man who can taste PTC but cannot roll his tongue. His mother was taste-blind to the chemical. Show the possible children this couple could produce.
In genetics, the dash symbol (–) is a “wild card” that stands for either the dominant allele or the recessive allele; for example, A– means the individual has either the genotype AA or Aa. Two genes that undergo independent assortment affect coat color in Duroc pigs. Each gene has two alleles, one of which is dominant for coat color. Genotypes of the form A– B– are red, those of the form A– bb and aa B– are sandy, and genotype aa bb is white. What ratio of red:sandy:white is expected from the cross Aa Bb x Aa Bb?
From the BbHh x BbHh dihybrid cross where BB or Bb represented full melanin and bb represented no melanin, and where HH or Hh represented black fur and hh represented brown fur, interpret the 9 : 3 : 3 : 1 phenotypic result from the F generation. Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a 9 had no melanin and black fur, 3 had no melanin and brown fur, 3 had no melanin and black fur, 1 had no melanin and brown fur b 9 had no melanin and brown fur, 3 had full melanin and brown fur, 3 had no melanin and black fur, 1 had full melanin and black fur c 9 had no melanin and black fur, 3 had full melanin and brown fur, 3 had no melanin and black fur, 1 had no melanin and brown fur d 9 had full melanin and black fur, 3 had full melanin and brown fur, 3 had no melanin and black fur, 1 had no melanin and brown fur
The gene for flower color in snapdragons displays incomplete dominance. Snapdragons homozygous for the allele for red flower color have the genotype FRFR and have red flowers. Snapdragons homozygous for the allele for white flower color have the genotype FWFW and have white flowers. Heterozygous snapdragons, with the genotype FRFW, have pink flowers. A snapdragon that has pink flowers is crossed with a different snapdragon that has pink flowers. What percentage of the offspring is expected to have red, white, and pink flowers?
In a particular plant, two genes control leaf shape and color. Round leaves (R) are dominant to jagged leaves (r). Yellow fruits (Y) are dominant to white fruits (y). If you crossed a homozygous round, heterozygous yellow plant with a heterozygous round, white plant, what are the genotypes of the plants involved in this cross?

A pea plant is heterozygous for both pod shape and color. I is the allele for dominant, inflated pod; i is the allele for recessive, constricted pod.
