In some bees, thin stripes (s) are dominant over thick stripes (s) and black eyes (b) are dominant over gray eyes (b). complete a dihybrid cross for parents with the genotypes: ssbb × ssbb and answer the following in complete sentences.

describe how you would set up a punnett square for this cross.
list the likelihood of each possible offspring genotype.
list the likelihood of each possible offspring phenotype.

Genotypic Ration -

SsBB: ssBB: SsBb:ssBb  is 4: 4:4:4

Likelihood of occurrence is  

SsBB: 25 %

ssBB: 25 %

SsBb:25 %

ssBb:25 %

Phenotypic ratio -

thin striped black eye :  thick striped black eye

8 : 8

1: 1

Likelihood of occurrence is  

thin striped black eye :  50%

thick striped black eye : 50%

Explanation:

The genotype of  two parents is SsBB and ssBb

The alleles for cross for parent with genotype SsBB are  SB, SB, sB, SB

The alleles for cross for parent with genotype ssBb are sB, sb, sB, sb

The cross between the two parents is represented by a punnet square as given below -

        SB          SB          sB         sB

As given thin stripes (S) are dominant over thick stripes (s) and black eyes (B) are dominant over gray eyes (b).

So the phenotype for genotype of offsping is as follows

SsBB: thin striped black eye

ssBB: thick striped black eye

SsBb: thin striped black eye

ssBb: thick striped black eye

Phenotypic ratio -

thin striped black eye :  thick striped black eye

8 : 8

1: 1

Likelihood of occurrence is  

thin striped black eye :  50%

thick striped black eye : 50%

the  different  of  these  two  are  that  they  differently  handle  their  team.

an  expressive  leader  focuses  on  the  task  at  hand  and  make  sures  that  their  goal  is  achieved.  they  accurately  finish  the  task.  an  instrumental  leader  on  the  other  hand  works  on  the  unity  of  the  group,  they  care  more  about  their  employees.  all  the  while  creating  a  good  environment.
