Crow chaired the Department of Medical Genetics for five years and the Laboratory of Genetics (Genetics plus Medical Genetics) for a total of eight years. He also served as Acting Dean of the UW Medical School for 2 years. He was President of the Genetics Society of America and the American Society of Human Genetics.
The Watkins Landrace Wheat Collection is a unique resource due to the historical nature of being collected in the 1930’s before widespread globalisation of trade, and before intensive selective breeding in wheat to develop high-yielding elite varieties, which resulted in a significant loss of genetic diversity, including resilience traits.

Consider the gene pool of a seed orchard crop or other source of seeds with parents. The gene pool is large as there are many seeds in a seed crop, so there is no genetic drift. The probability that the first gene originates from genotype i in the seed orchard is p i, and the probability that the second originates from genotype j is p j.
The International Treaty on Plant Genetic Resources for Food and Agriculture [2] (also known as ITPGRFA, International Seed Treaty or Plant Treaty [3]) is a comprehensive international agreement in harmony with the Convention on Biological Diversity, which aims at guaranteeing food security through the conservation, exchange and sustainable use of the world's plant genetic resources for food ...
Intensive research in molecular genetics has led to the development of recombinant DNA technology (popularly called genetic engineering). Advancement in biotechnological techniques has opened many possibilities for breeding crops. Thus, while mendelian genetics allowed plant breeders to perform genetic transformations in a few crops, molecular ...
Mutation breeding, sometimes referred to as "variation breeding", is the process of exposing seeds to chemicals, radiation, or enzymes [1] [2] in order to generate mutants with desirable traits to be bred with other cultivars. Plants created using mutagenesis are sometimes called mutagenic plants or mutagenic seeds.
Candy canes are a peppermint treat long associated with Christmas. Learn their history, including why they were first made with red and white stripes.
The heavy ones land nearby to the parent plant, whereas fluffy seeds float further away on the wind. In urban environments, seeds that float far often land on infertile concrete. Within about 5–12 generations, the weed evolves to produce significantly heavier seeds than its rural relatives.
