Mendel wondered if the separation of alleles on one gene had any effect on the separation of alleles on another. To test this, Mendel looked at plants that were pure breeding for two traits at once—he crossed plants that were pure breeding for two traits with plants that were pure breeding for the opposite forms of the same traits. In conducting and analyzing those crosses, Mendel was able to discover predictable patterns and ratios in the phenotypes of the F1 and F2 offspring. Problem (Purpose) In this lab, you will explore mouse coat colour and eye colour as two separate genetic traits. Procedure Use the following information to answer the analysis questions. Black fur is dominant so the offspring must inherit one “F” allele to be black. White fur is recessive so the offspring must inherit two “f” alleles to be white. Black eyes are dominant so the offspring must inherit one “E” allele to be black eyed. Red eyes are recessive so the offspring must inherit two “e” alleles to be red eyed Complete the Punnett Square The Punnett square represents possible offspring (represented by letters in boxes) of a cross between two dihybrids, FfEe x FfEe. 1, Of the 16 offspring represented in the Punnett Square, how many have black fur and black eyes? (Hint: Look for mice with at least one F and at least one E allele.) what are the 2 possible genotypes of these mice? 2. How many have black fur and red eyes? How many have white fur and black eyes? 3, How many have white fur and red eyes? 4, Given the following genotypes for the parents: a. FfEe and ffee what percentage of the offspring will have white fur and red eyes

Procedure
Use the following information to answer the analysis questions.
-
Black fur is dominant so the offspring must inherit one “F” allele to be black.
-
White fur is recessive so the offspring must inherit two “f” alleles to be white.
-
Black eyes are dominant so the offspring must inherit one “E” allele to be black eyed.
-
Red eyes are recessive so the offspring must inherit two “e” alleles to be red eyed
Complete the Punnett Square
The Punnett square represents possible offspring (represented by letters in
boxes) of a cross between two dihybrids, FfEe x FfEe.1, Of the 16 offspring represented in the Punnett Square, how many have black fur and black eyes? (Hint: Look for mice with at least one F and at least one E allele.)
