You are to discover the chromosomal location (autosomal or X linked) and mode of inheritance
for two new fly mutations swiss cheese (sc) and dachshund (da) The homozygous swiss cheese
(scsc) phenotype has holes in it's brain The homozygous dachshund (dada) has short legs
PARENTS Cross Male double homozygous mutants sc da with Female wild wild SC DA are to
be crossed BUT FIRST you don't know if either gene is on the X chromosome Parental diploid
genotypes could be: male scscdada female SCSCDADA if Both genes autosomal or Male
XscYdada female XSCXSCDADA if sc on the X chromosome and da autosomal or Male
scscXdaY female SCSCXDAXDA if da on the X chromosome and sc autosomal What are the
expected phenotypes and phenotype ratios for each of the above three F1 x F1 Punnett squares
assuming: (REMEMBER FOR X-LINKED CROSSES THE PHENOTYPE RATIO MIGHT BE
DIFFERENT FOR THE 8 MALES FROM THE RESULTANT 8 FEMALES) Predictions Use
this area to create PHENOTYPE PREDICTIONS that reflect the above Punnett squares for the
F2 generation if the inheritance of the mutant trait is: (Label clearly the phenotype).
REMEMBER: Example for Mendelian dominant recessive there are 4 possibles. DO ALL
FOUR a) both WILD alleles are DOMINANT b) both MUTANT alleles are DOMINANT c)
ONE MUTANT allele is DOMINANT and WILD allele for other gene are DOMINANT d)
Reverse of c For autosomal Punnett - dominant or recessive, For two sex linked Punnett -
dominant or recessive, incomplete dominant (for both sex linked and autosomal) (take a guess on
what phenotype might look like), lethal dominant as embryo (sex linked and autosomal) IS THIS
EVEN POSSIBLE lethal recessive as embryo. ( sex linked and autosomal) IS THIS EVEN
POSSIBLE
