Answer:
Phenotypes: All Brown Hair Color and All Short Hair Length
Genotypes:
Homozygous dominant hair color and homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).
Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)
Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)
Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)
Explanation:
Hair color :
B = dominant brown
b = recessive white
Hair length :
S = dominant short
s = recessive long
The dihybrid cross between parents with the genotypes:
BBSS × BbSs
If BBSS self crossed; we have the following traits= BS, BS, BS, BS
If BbSs self crossed; we have the following traits= BS, Bs, bS, bs
The dihybrid cross is as follows:
BS BS BS BS
BS BBSS BBSS BBSS BBSS
Bs BBSs BBSs BBSs BBSs
bS BbSS BbSS BbSS BbSS
bs BbSs BbSs BbSs BbSs
Phenotypes = All Brown Hair Color and All Short Hair Length
Genotypes include:
Homozygous dominant hair color and homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).
Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)
Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)
Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)
