Question

1). What type of genetic interaction is seen between the three alleles in the ABO blood type system?

a. Codominance (A&B) and complete dominance (A&B compared to O)

b. Codominance (A&B), and incomplete dominance (A&B compared to O)

c. Complete dominance (A&B) and codominance (A&B compared to O)

d. Incomplete dominance only

e. Codominance only

2)

Two heterozygous hairy Ewoks have two baby Ewoks. What is the chance that both offspring will have the same genotype?

Select one:

a. 3/8

b. 1/16

c. 9/16

d. 1/4

e. 5/8

Answer 1

1) e

Indeed, "codominance" is the specific term for a system in which an allele from each homozygote parent combines in the offspring, and the offspring simultaneously demonstrates both phenotypes. An example of codominance occurs in the human ABO blood group system.

2)1/4

Heterozygous refers to the diploid condition where both alleles of the genotype are ... For heterozygous genotypes, haploid gametes will be different for the given ... Homologous chromosome pairs have the same loci, thus genes 2. ... A certain hypothetical species called an EWOK has a gene
