Question

in rabbits, black fur (b) is dominant over brown fur (b). consider the following cross between two rabbits.
bb x bb
punnett square image with cells labeled 1,2,3,4
refer to the illustration above. the device shown, which is used to determine the probable outcome of genetic crosses, is called a

• punnett square.
• phenotypic paradox.
• mendelian box.
• genetic graph.

Explanation:

The device shown in the illustration, used to determine the probable outcome of genetic crosses (like the cross between two Bb rabbits here), is a Punnett square. A Punnett square is a tool in genetics to predict the genotypes of offspring from a particular cross. The other options: "phenotypic paradox" is not a standard term for this tool, "Mendelian box" is not the correct name, and "genetic graph" is also not the term used for this device.

Answer:

A. Punnett square
