Examples of codominance include ABO blood type
and coat color in cattle.
In short horn cattle coat color pattern is
determined by two alleles (CR = red; CW = white)
that are both equally expressed. CRCW cattle are
roan (red and white patches); therefore, both
alleles affect the phenotype equally.
The ABO system of blood typing exhibits
codominance in humans. There are 3 alleles for the
gene that determine ABO blood type (IA and IB are
codominant alleles; allelei is recessive to alleles IA
and IB). IAIA and I^i are type A; I®I® and IPi are type
B; I^IB is type AB; ii is type O
Practice Problem 4:
4a. If a man with blood type O marries a woman
that is blood type AB, what are the predicted
genotypes and phenotypes of their children?
4b. If a man with blood type A (I^i) marries a
woman with blood type AB, what are the
predicted genotypes and phenotypes of their
children?
A geneticist is studying memory recall and is trying to locate specific genes that have varying effects on a given phenotype (physical trait) in the study subjects.
These locations of these genes are referred to as:
Group of answer choices
Genomic spatial identifications
Epigenetic regulators
Evocative response indicators
Quantitative trait loci
What is the Strategy for genetic mapping of quantitative trait loci (QTLs) influencing complex traits?

The gene si is associated with the silky fur phenotype, and It is associated with the long-tailed phenotype. Both si and It are recessive mutations with respect to wild type. Le is a dominant mutation that confers the lethargic phenotype. The geneticist first crosses true-breeding lethargic rabbits to true-breeding silky fur, long-tailed rabbits. Next, the geneticist backcrosses the Fj progeny to the silky fur, long-tailed parents, and obtains the results reported in the table.

Diabetes is certain if eight or more of the alleles at these six loci are of the “contributing” variety. An uppercase letter indicates an allele that contributes to diabetes and a lowercase symbol indicates a noncontributing allele. A married couple wants to know the probability of producing a child who is at severe risk of type 2 diabetes.
