1) In mice, albinism (g) is recessive to grey coat colour (G). A grey mouse mated with an albino mouse. Over the course of several months, 38 pups were born. Out of 38 pups, 17 had a grey coat, and 21 were albino.

Which of the following rows correctly identifies the parental and F1 generation genotypes?

a.      Parental Cross                    F1 Genotypes
             G G x  g g                                      Gg


b.     Parental Cross                          F1 Genotypes
        G g  x  g g                                       Gg and gg


c.       Parental Cross                     F1 Genotypes
              G g  x  G g                          GG, Gg and gg


d.       Parental Cross                       F1 Genotypes
              G g  x  G G                               GG and Gg




2) Which of the following statements describes Mendel’s Law of Segregation?

a. The dominant allele is represented with an uppercase letter and the recessive allele is represented with a lowercase letter.

b. Dominant alleles are always expressed in a homozygous or heterozygous individual.

c. A Punnett square can be used to predict the outcome of a parental cross.

d. A Bb individual will produce B and b alleles, while a bb individual will only produce a b allele.






3) SEE IMAGE ATTACHED TO ASNWER THE FOLLOWING QUESTION:

The diagram above depicts

a. the law of segregation

b. nondisjunction

c. complete dominance

d. crossing over





4) In tomatoes, red fruit (R) is dominant over yellow fruit (r).

Red tomato plants were cross pollinated with yellow tomato plants.  The next generation of plants produced no yellow fruit.

Which of the following rows identifies the genotype and the phenotype of the parental red tomato plants respectively? 

a. red; Rr

b. red; RR

c. Rr; red

d. RR; red

6) Sarah and George have been married for 6 years. They had a daughter 5 years ago and her blood type is AB. Sarah had complications during her birth and was transfused with three pints of type A blood. The couple recently welcomed a new baby boy to their family.

He has the blood type O. What are Sarah and George’s genotypes?

a.   Sarah's Genotype                     George's Genotype
              I^A I^A                                                    ii


b. Sarah's Genotype                     George's Genotype
             I^A I^A                                              I^B i
 

c. Sarah's Genotype                       George's Genotype
                I^Ai                                                I^B I^B
 

d. Sarah's Genotype                       George's Genotype
                 I^A i                                               I^B i

b. Dominant alleles are always expressed in a homozygous or heterozygous individual.

c. A Punnett square can be used to predict the outcome of a parental cross.

d. A Bb individual will produce B and b alleles, while a bb individual will only produce a b allele.


Note: The Bb individual will produce the B and b alleles as during the formation of gametes the alleles segregate from each other. Bb is a heterozygous individual, and according to the law of segregation, the alleles get separated. From a bb individual, the only gametes possible is b, as it is a homozygous recessive condition. Therefore, option a is the description of the law of segregation.
