• All of the offsprings will have the same phenotype (short), but two different genotypes (TT and tt)

• All of the offsprings have the same phenotype (short), and the same genotype (tt)

• All of the offsprings will have the same phenotype (Tall), but two different genotypes (TT and Tt)

• All of the offsprings will have the same phenotype (tall), and the same genotype (Tt)

The allele for free earlobes (E) id dominant over attached earlobes (e), This pedigree shows those affected individuals who inherited the allele for attached earlobe across three generations of a family.

Individual N marries a woman who is heterozygous for free earlobes. What is the probability that they will have a child who has attached Earlobes?

• 0%

• 25%

• 50%

• 100%

Examine this pedigree showing the inheritance of an autosomal trait.

Individuals with recessive phenotype are shaded darker than those with the dominant phenotype. If this trait is represented by letter R, what is the genotype of letter B?

• rr

• RR

• Rr

• RR or Rr

Use the pedigree showing the inheritance of an autosomal trait to answer the question, Individuals with recessive phenotype are shaded darker than those with the dominant phenotype.

If individual J marries a woman with recessive phenotype, what is the likelihood that one of their children would also have the recessive phenotype.

• 0%

• 25%

• 50%

• 100%

The pedigree shows a certain autosomal recessive genetic disorder that is coded for by the allele g.

What is the genotype of individual J.

• GG

• Gg

• gg

• GG or Gg

In Hereford cattle, one gene determines whether or not cow will have horns. The allelle that produces horns is recessive (h) and allelle that results in no horns is dominant (H).

If two heterozygous cows mate, what are the predicted phenotypes of their offsprings.

• 0% horns; 100% no horns

• 25% horns; 75% no horns

• 75% horns; 25% no horns

• 100% horns; 0% no horns
