Genetics
Explain the concept illustrated in this image:
Codominance: both alleles are equally dominant
Philanderdats live on Mars. Skin color is blue (SB) or red (SR) if homozygous. The heterozygous (SBSR) has red and blue
spotted skin. Cross a blue female philanderdat and a spotted male philanderdat?
P gen: __________ x ___________
Genotypic and Phenotypic Ratio
For offspring: _________
Honors- Quarter 3 Review
Incomplete Dominance: neither allele is completely dominant
Cross two 4 o’clock plants. (These plants are known for their incomplete dominance characteristics.) Cross one
homozygous (R) red plants with one white plant (W). What will be the result of this P generation cross?
P generation cross: ________ x __________
Genotypic & Phenotypic Ratio: __________
Dihybrid Crosses
crossing two traits together, like fur color and fur texture
a. List the possible gametes from Parent A with DDMM. ________
b. List the possible gametes from Parent B with DdMM.__________________
c. List the possible gametes from Parent C with Ddmm._____________________
