In peas, tall stems & axial flowers are dominant to dwarf stems & terminal flowers, which are recessive.  If you have a tall, axial flowering plant and want to determine its genotype, what kind of pea should you breed it with?   a. tall & axial flowering   b. dwarf & axial flowering   c. dwarf & terminal flowering   d. tall & terminal flowering

A researcher at ASU is studying the exotic Unicorn Fairy plant. The plant has three genes of interest with the dominant alleles being T-tall, H=hairy leaves and P=purple flowers. The three genes are located in different chromosomes. A trihybrid plant is crossed with a plant that is heterozygous for T and homozygous recessive for the other two genes. What is the probability of getting offspring that is tall, has hairy leaves and white flowers? 9/64 5/8 8/64 O 3/64 O 3/16

A GENETICIST DISCOVERS A NEW MUTATION IN PEAS THAT CAUSES MOTTLED FLOWER COLOR. SHE CALLS THIS MUTATION SPOTTY AND DETERMINES THAT IT IS DUE TO AN AUTOSOMAL RECESSIVE ALLELE (S). SHE WANTS TO DETERMINE WHETHER THE GENE ENCODING SPOTTY IS LINKED TO THE RECESSIVE GENE FOR FLOWER COLOR (WHITE, W, IS RECESSIVE TO PURPLE). SHE CROSSES A PLANT HETEROZYGOUS FOR BOTH TRAITS WITH A PLANT HOMOZYGOUS RECESSIVE FOR BOTH TRAITS AND OBTAINED THE FOLLOWING PROGENY:NORMAL, PURPLE: 86 NORMAL, WHITE: 14 SPOTTY, PURPLE: 10 SPOTTY, WHITE: 90• WHAT ARE THE GENOTYPES FOR EACH OF THESE FOUR PROGENY TYPES?• WHICH ALLELES ARE FOUND ON EACH CHROMOSOME OF THE DOUBLE HETEROZYGOTE PARENT? (USE SLASH NOTATION.)• WHAT IS THE DISTANCE IN CM BETWEEN THESE TWO GENES?
