Question

a brown rabbit with long ears, bbll, is crossed with a white rabbit with long ears, bbll. the brown allele, b, is dominant fur color allele, and the long - eared allele, l, is the dominant ear length allele. using the provided information in the previous sentence, select the punnett square boxes that should contain offspring that are white with short ears.

Explanation:

Step1: Determine the recessive alleles

The recessive fur - color allele is $b$ (white) and the recessive ear - length allele is $l$ (short). Offspring with white fur and short ears must have the genotype $bbl$.

Step2: Analyze the gametes

The brown long - eared rabbit ($BbLl$) produces gametes $BL$, $Bl$, $bL$, $bl$. The white long - eared rabbit ($bbLl$) produces gametes $bL$ and $bl$. The combination of gametes to get $bbl$ is when a $bl$ gamete from the $BbLl$ parent combines with a $bl$ gamete from the $bbLl$ parent.

Answer:

The box where the $bl$ gamete from the $BbLl$ parent (top - row) and the $bl$ gamete from the $bbLl$ parent (left - column) intersect.
