Merle (dog coat): Merle is a pattern in a dog's coat.  "Merle" comes in different colors and patterns.  Some have blue patches throughout and are considered blue "merle"; same with red, and chocolate, although some describe merle as only a "pattern".  DNA testing identifies the "Merle" gene but not the variety of colors and patterns seen in the coats of the dogs with the gene.  A dilute black (BB or Bb) dog is generally known as blue, but a dog with a merle coat does not test BB or Bb but still is a blue dilute from the "merle" gene The merle gene creates mottled patches of color in a solid or piebald coat, blue or odd-colored eyes, and can affect skin pigment as well.  Health issues are more typical and more severe when two merles are bred together, so it is recommended that a merle be bred to a dog with a solid coat color only.

Financial gerontology: Financial Gerontology is a multidisciplinary field of study encompassing both academic and professional education, that integrates research on aging and human development with the concerns of finance and business.  Following from its roots in social gerontology, financial gerontology is not simply the study of "old people" but emphasizes the multiple processes of aging.  In particular, research and teaching in financial gerontology draws upon the "four kinds" or four lenses through which aging and finance can be viewed: population aging, individual aging, family aging, and generational aging.  The field.  While it is not always true that "demography is destiny," demographic concepts, issues, and data play a substantial role in understanding the dynamics of financial gerontology.  For example, through the lens of population aging, demography identifies the number of persons of different ages in cities and countries—and at multiple points in time.  Through the lens of individual aging, demography notes changes, typically improvements in human longevity.  Beginning in its founding years in the beginning of the 21st century, one primary interest of the field has been on the baby boomers and their relationships with their parents.  The impact of these two kinds of aging on finance are reasonably apparent.  The large and increasing number of older persons population aging in a society, however "old age" is defined, and the longer each of those persons lives [individual aging], the greater the impact on a society's pattern of retirement, public and private pension systems, health, health care, and the personal and societal financing of health care.  The focus on boomers illustrates the other two lenses or "kinds" of aging.  How boomers deal with the social, emotional, and financial aspects of their parents' aging is a central aspect of family aging.  And how boomers may differ from their parents born and raised twenty to forty years earlier, and differ from their Generation X and Millennial children and grandchildren, are substantial aspects of generational aging.
