A rock used as a percussor to detach flakes from an objective piece. These usually show signs of impact damage such as crushed edges. A group of muscles including biceps femoris, semimembranosus, and semitendinosus, extending from the ischial tuberosity to the back of the femur and top of the tibia, mainly acting to flex the hip joint. A teardrop or pear shaped, bifacially flaked stone implement. Having only a single set of chromosomes, half the number in a normal somatic cell.
Gametes are normally haploid.
Sets of genes at more that one locus. A hammerstone made of hard rock. A extension of Mendel's laws of inheritance that describes the expected relationship between gene frequencies in natural populations and the frequencies of individuals of various genotypes in the same populations. When both DNA strands contain 5-BUdR, the chromatid stains less intensely than when only one DNA strand contains the analog. When cells are grown in the presence of 5-BUdR for two replication cycles, the two sister chromatids stained differentially are called harlequin chromosomes.
