Here are data pertaining to red vs brown eye color in Drosophila. Given the data, what can you say about the mode of inheritance of brown vs. red (wild type) eye color? What about the genotypes of the sets of parents, and of the offspring? offspring: red brown parents: brown x brown 0 92 red x red 79 0 red x red 64 21 red x brown 100 0 red x brown 54 60

Pigeons may be checkered or plain. In a series of matings, the following data were obtained: Checkered Plain a) checkered x checkered 36 0 b) checkered x plain 38 0 c) plain x plain 0 35 The F1 were mated with these results (parental cross is indicated in parentheses)

Which allele is dominant? What are the parental genotypes? Determine genotypes of parents and offspring for each cross. http://www.vdperre.be/duiven/formerpigeons.htmlA red swordtail with crescent spot was crossed to true-breeding olive spotless fish and the following progeny obtained: 15 red spot,13 red spotless,16 olive spot,14 olive spotless a. What can we conclude about the inheritance; what are the parental genotypes? b. Create symbols for alleles, write out parental genotypes c. Write out genotypes of progeny...
