It’s a commonly observed habit in families to draw likenesses between members of the youngest generation and their ancestors. “This baby has a smile like her mother,” one would say, or, “He has ...

Genetics is important to our understanding of selection for at least three reasons: first, although the concept of selection seems obvious, it was not until selection was linked to Mendelian genetics ...

Basic concepts in quantitative genetics, including Mendelian genetics, gene action (additive, dominant, recessive), heritability, liability threshold model, means, variances, structure of DNA, types ...

The year was 1900. Three European botanists — one Dutch, one German and one Austrian — all reported results from breeding experiments in plants. Each claimed that they had independently discovered ...

Challenging a scientific law of inheritance that has stood for 150 years, scientists say plants sometimes select better bits of DNA in order to develop normally even when their predecessors carried ...

Gregor Mendel described his experiments with pea plants and proved that genes are transmitted in discrete units, with certain ...
