Here are the answers to your Bikini Bottom Genetics worksheet.
1. Genotypes: Heterozygous (He) or Homozygous (Ho)
*
TT: Ho (Homozygous)
*
Bb: He (Heterozygous)
*
DD: Ho (Homozygous)
*
Ff: He (Heterozygous)
*
tt: Ho (Homozygous)
*
dd: Ho (Homozygous)
*
Dd: He (Heterozygous)
*
ff: Ho (Homozygous)
*
Tt: He (Heterozygous)
*
bb: Ho (Homozygous)
*
BB: Ho (Homozygous)
*
FF: Ho (Homozygous)
Which of the genotypes in #1 would be considered purebred?
Purebred means the organism is homozygous (has two of the same letters).
Answer: TT, DD, tt, dd, ff, bb, BB, FF
Which of the genotypes in #1 would be hybrids?
Hybrid means the organism is heterozygous (has two different letters).
Answer: Bb, Ff, Dd, Tt
***
2. Determine the phenotype for each genotype
Yellow body color is dominant to blue.
*(Let's assume Y = Yellow and y = Blue)*
*
YY: Yellow body
*
Yy: Yellow body (because Yellow is dominant)
*
yy: Blue body
Square shape is dominant to round.
*(Let's assume S = Square and s = Round)*
*
SS: Square shape
*
Ss: Square shape (because Square is dominant)
*
ss: Round shape
***
3. Give the genotypes that are possible for Patrick
A tall head (T) is dominant to short (t).
*
Tall: TT or Tt
*
Short: tt
Pink body color (P) is dominant to yellow (p).
*
Pink body: PP or Pp
*
Yellow body: pp
