8. The genotype of F1 individuals in a tetrahybrid cross is AaBbCcDd. Assuming
independent assortment of these four genes, what are the possibilities that F2 ossrping
would have the following genotypes?
а. Aabbccdd
b. AaBbСcDd
с. ААВВСCDD
d. AaBBccDd
е. AаBBCСdd
9. What is the probability that each of the following pairs of parents will produce the
indicated offspring? (assume independent assortment of all gene pairs)
а. ААВВССх bbcc 3D AаBbСс
b. AАBbСс х АаBbСс %3D АAЬЬСС
с. АаBbСс х АаBbСс 3 АаBbСс
d. aaBbCС х AАBbсс —D AаBbСс
10. In humans, the genes for coloblindedness and hemophilia re both located on the X
chromosome with no corresponding gene in the Y. These are both recessive alleles.
a. If a man and a woman, both with normal vision, marry and have a colorblind son,
draw the Punnet square that illustrates this.
b. If the man dies and the woman remarries to a colorblind man, draw a Punnet
Square showing the type of children could be expected from hre second marriage.
How many/what percentages of each could ne expected.
