Fairy Genetics Mendelian autosomal recessive inheritance Characteristic Dominant Gene Recessive Gene Number of wings Two (W) Four (w) Pink (S) Skin color Green (s) No dust (d) Pixie dust Dust (D) l. Use the information for fairy traits to write the phenotype for each item (b) dd (a) WW (c) Dd (d) Ss 2. Use the information in the chart to write the genotype for each trait below. (a) Green skin (b) Two wings (c) Pink skin (d) No pixie dust 3. Determine the genotypes and phenotypes for each using the information in the chart. (a) Heterozygous number of wings (b) Homozygous dominant skin color (c) Homozygous recessive dust (d) Heterozygous skin color

Solution

1)WW is two wings (dominant noncarrier), dd no pixie dust (Autosomal recessive), Dd is dust pixie (carrier of mutation), Ss is pink skin color (carrier of mutated gene)

2) Green skin ss , a homozygous recessive trait only shows this phenotype.

Two wings WW, Ww these include both homozygous dominant and heterozygous carriers of the mutated allele showing two wings phenotype

pink skin Ss, SS result of dominant allele expressing in both homo and heterozygous genotypes

no pixie dust dd autosomal recessive inheritance where only dd shows this genotype.

3)Heterozygous number of wings- two wings Ww

homozygous dominant skin color-SS pink skin

Homozygous recessive dust - dd no pixie dust

Heterozygous kin color- pink color Ss

4) Fawn (Ss) and rosetta (Ss) have pink skin due to their heterozygous carrier nature of mutated skin color. green skin is inherited when daughter silvermist is carrying homozygous recessive allele.

SS is dominant and causes pink phenotype, Ss are pink phenotype carriers and 50% chances of inheritance, ss have green phenotype and have 25% chances of inheritance (silvermist belongs to this category).
