A Link Between Staple Length and Depth of Color As part of our work using data from the AOA EPD database to examine whether fleece color affects the expression of fleece traits, we looked at the relationship between color and the EPDs for staple length for over 1300 males in the EPD database.  We found a pattern that suggests that faster fleece growth rates have a visible dilutive effect on the color we see in fawn, beige and white animals, by increasing the length of the hair relative to the...
Does Depth of Color Affect the Expression of Other Fleece Traits? We ask the question above as a short lead-in to an only slightly longer – but quite interesting – look at the possible connection between the depth of color of an animal’s fleece and the curvature of the fibers in that fleece, discussed in our library article on this topic.    Our curiosity about this was stimulated by analysis of the amount of pigment present in the fiber of different colored alpacas that was published in Kylie Munyard’s 2011 paper, “Inheritance of...

No Such Thing as a Dominant White? If any of the assertions below contradict what you believe about alpaca base coat color genetics, it’s definitely worth reading this blog post and continuing on to a very friendly, fun-loving statistical analysis that is available in our website’s library! 1. First, all white alpacas can produce color when they are bred to it. There is no such thing as a homozygous dominant white animal.  In fact, a pink-skinned white is in some ways as recessive a creature as a true...
Alpaca Temperatures and Fertility:  We Checked Some Numbers                                                         December 2016.  Those of you who are familiar with our alpaca breeding effort know that we are quantitatively oriented and research-focused.  We also like to share what we learn as broadly as possible.  Some of our research results – especially those from projects led by the human embryologist and fellow alpaca breeder Dr. Kim Gleason, of Dancing Horse Farm – find their way to formal publication.  Sometimes, though, there is incremental yield from our research and data collection that we...
