The purple colour results from the formation of a purple pigment in the skin of the kernel. The gene locus for the colour trait is designated “R”. The wrinkled phenotype arises from a decrease in the amount starch produced within the kernel. The gene locus for the texture trait is designated “S”. Present the data as monohybrids (Xx, XX, xx) for all five corn cobs andfor the plant. Present the colour and texture phenotypes with their associated genotypes in separate tables. Your first table should include the corn ID, the number of purple kernels, the number of yellow kernels, and the phenotypic ratio between the two kernel colours. Present the texture results in the same format to a separate table. What is the dominant phenotype for kernel colour in your assigned cornplant? What is the dominant phenotype for kernel texture in your assigned cornplant?
1. Selective breeding often comes with benefits and drawbacks. Provide 2-3 examples from the text that supports this statement. (This answer should be at least 5-6 sentences) 2. Should we continue to selectively breed animals or plants? Why or why not? Use multiple examples (broiler chicken, Belgian blue cows, dogs, dairy cows) in your response. Your answer should be at least 5-6 sentences.
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?
Eight mutant strains of flowers were found to have white petals. Normal flowers are pink. The flower strains were all mated in pair-wise combinations to use complementation analysis to determine the number of genes involved in flower color. Data are tabulated below. + indicates wild type (pink flowers). indicates mutant (white flowers). 1 2 3 4 5 6 7 8 1 + 4 6 + + + 8 How many genes are mutated in this experiment?

A nutritionist is interested in collecting data to develop a healthy eating program at a local high school. In particular, the nutritionist is interested in collecting the students' body mass index value and their daily caloric intake. The nutritionist wishes to study the relationship between these two quantitative pieces of data. What would be the best graph to display this type of data?
