Okay so always remember genotype is the genetic information and phenotype is the observable trait. Homozygous is going to be the same wether it’s dominant or recessive such as TT or tt. Heterozygous will be different such as Tt.
1. A. Genotype is “TT” and phenotype is “tall”
B. Genotype is “tt” and phenotype is “short”
C. Genotype is “Tt” and phenotype is “tall” because tall is the dominant trait
2. A. Genotype is “YY” and phenotype is “yellow”
B. Genotype is “yy” and phenotype is “green”
C. Genotype is “Yy” and phenotype is “yellow”
3. A. Genotype is “WW” and phenotype is “smooth”
B. Genotype is “ww” and phenotype is wrinkled”
C. Genotype is “Ww” and phenotype is “smooth”
4. A. WW (homozygous smooth) x ww (homozygous wrinkled)
B. W or W and w or w
Not sure what number 5 is referring to and unfortunately can’t draw a punnet square for you for number 6 but I could answer any questions you have as you do it!
