Follow the instructions below. Printout the results sheets, complete the Punnett Squares and results and give your completed assignment to your instructor.
- print out this sheet of partental phenotypes and genotypes
- the last four numbers of your social secturity number are the numbers of the crosses you must investigate
- mark each number (4 all together) on the parent sheet and put your name and section at the top of the page
- if there are any duplicate numbers, choose a replacement cross
- print out the results sheet(s)
- use these results sheets to perform the Punnett Square on the each of the various genetic crosses you have been assigned
- work out all the possible haploid gametes that each parent can produce by meiosis
- write each gamete genotype along one side of the Punnett Square (male and female separately)
- fill in the internal boxes of the square with the genotypes of the offsprings that would be produced
- from the Punnett Square results, determine the range of phenotypes obtained, put each phenotype into one of the boxes at the bottom of the page
- count the number of offspring that have that particular phenotype
- record that number
- put your name and section number at the top of the page and give your results to your instructor as requested
