Should Pets be Cloned
By: Janice Suchoski
Cloning, by definition is to create a replica of something from the genetic material of that something. That the object is a living entity, individual of any other seems to be more of a challenge than an ethical consideration to those caught up in...
Genetic traits of the human eye: Melanin and myopia
By: Tami Port MS
Before discussing the genetics of eye pigment and myopia, it helps to first review some of the terminology related to these aspects of heredity. * Alleles: Variations of a Gene *Alleles are variations of a gene. A diploid organism gets one set of alleles (genes)...
The Ethical Difference between Cloning Animals and Humans
By: Alicia M Prater PhD
Boundaries exist between humans and animals in regards to medical testing, housing, ownership, euthanasia, purchased breeding, and a number of other areas, so why would it be different for cloning? A slippery slope would indicate that one could easily go from one position to another...
Genetic terminology: Diploid and haploid cells
By: Tami Port MS
Genetics is rife with potentially confusing scientific terminology associated with chromosomes and chromosome number. What is ploidy, and which cells are haploid? Which are diploid? What are homologous chromosomes? What are duplicated chromosomes? The intent of this article is to clarify some of this lingo...
Genetic terminology: Difference between duplicated and homologous chromosomes
By: Tami Port MS
Students often become confused during discussions of genetics, when it comes to the terminology associated with chromosomes and chromosome number. What are homologous chromosomes? What are duplicated chromosomes? What are sister chromatids? How do all of these terms differ and how do they relate to...

DNA telepathy: Genes recognize base pair sequence homology
By: Tami Port MS
A new study demonstrates that genes recognize other genes that have similar base pair sequences, a discovery that can help us understand DNA repair and genetic diversity.* Telepathic Genes *New research published in the January issue of the Journal of Physical Chemistry suggests that...
Animal or Human Cloning
By: Dan Creamer - 47733
The ethical questions surrounding human cloning are many and complex. Some people come at the issue from a religious perspective because the state of the art for embryonic cloning still destroys the embryo. Others worry about the science being used for nefarious purposes. The fear...
Dominant human genetic traits: Mid-digital hair, hand clasping and bent little finger
By: Tami Port MS
The one of the best ways to learn about genetics is to understand heredity first hand, by examining actual examples of the dominant and recessive traits that you possess. Here we will explore the characteristics of mid-digital hair, hand clasping, and bent little finger. Before...
Dominant human genetic traits: Facial dimples, chin cleft and free earlobes
By: Tami Port MS
The one of the best ways to learn about genetics is to understand heredity first hand, by examining actual examples of the dominant and recessive traits that you possess. Here we will explore the characteristics of facial dimples, chin cleft and free earlobes. Before delving...
