Answer

Explanation:

Problem 1:

Step1: Determine parent genotypes

Let B represent the dominant brown - color allele and b represent the recessive tan - color allele. The homozygous dominant brown mouse has genotype BB, and the heterozygous brown mouse has genotype Bb.

Step2: Create Punnett square

B B
B BB BB
b Bb Bb

Step3: Determine offspring genotypes and phenotypes

Genotypes: BB:Bb = 1:1. Phenotypes: All brown.

Problem 2:

Step1: Determine parent genotypes

Let W represent the dominant white - fur allele and w represent the recessive brown - fur allele. The two heterozygous white rabbits have genotype Ww.

Step2: Create Punnett square

W w
W WW Ww
w Ww ww

Step3: Determine offspring genotypes and phenotypes

Genotypes: WW:Ww:ww = 1:2:1. Phenotypes: White:Brown = 3:1.

Problem 3:

Step1: Determine parent genotypes

Let R represent the dominant red - flower allele and r represent the recessive white - flower allele. The two heterozygous red flowers have genotype Rr.

Step2: Create Punnett square

R r
R RR Rr
r Rr rr

Step3: Determine offspring genotypes and phenotypes

Genotypes: RR:Rr:rr = 1:2:1. Phenotypes: Red:White = 3:1.

Problem 4:

Step1: Determine parent genotypes

Let T represent the dominant tall - plant allele and t represent the recessive short - plant allele. The homozygous tall plant has genotype TT, and the heterozygous tall plant has genotype Tt.

Step2: Create Punnett square

T T
T TT TT
t Tt Tt

Step3: Determine offspring genotypes and phenotypes

Genotypes: TT:Tt = 1:1. Phenotypes: All tall.

Problem 5:

Step1: Determine parent genotypes

Let W represent the dominant white - rabbit allele and w represent the recessive non - white (assumed black here) allele. The heterozygous white rabbit has genotype Ww, and the homozygous black rabbit has genotype ww.

Step2: Create Punnett square

W w
w Ww ww
w Ww ww

Step3: Determine offspring genotypes and phenotypes

Genotypes: Ww:ww = 1:1. Phenotypes: White:Black = 1:1.

Answer:

Problem 1: Parent genotypes: BB and Bb. Offspring genotypes: BB:Bb = 1:1. Offspring phenotypes: All brown. Problem 2: Parent genotypes: Ww and Ww. Offspring genotypes: WW:Ww:ww = 1:2:1. Offspring phenotypes: White:Brown = 3:1. Problem 3: Parent genotypes: Rr and Rr. Offspring genotypes: RR:Rr:rr = 1:2:1. Offspring phenotypes: Red:White = 3:1. Problem 4: Parent genotypes: TT and Tt. Offspring genotypes: TT:Tt = 1:1. Offspring phenotypes: All tall. Problem 5: Parent genotypes: Ww and ww. Offspring genotypes: Ww:ww = 1:1. Offspring phenotypes: White:Black = 1:1.
