2. a journey over the sea. I was seasick as it was a very rough crossing.travesíaˈcrossbow noun a medieval type of bow fixed to a shaft with a mechanism for pulling back and releasing the string. ballestaˈcross-breed noun an animal bred from two different breeds. cruce, híbrido...
“each is so close to the spindle attachment that segregation invariably occurs at the Meiosis I without crossing over” [36]. Later work by the Oshima laboratory surprisingly revealed that the same behavior, which would be consistent with centromere linkage, was displayed by any combination of ...

Crossover will produce a new region provided that the cutting point occurs within a block rather than at one of the ends. Since there are L − 1 possible cutting points and Rμ (t) − 1 region boundaries, there will be a probability of L−Rμt/L−1 that the cutting site ...
A process similar to crossing-over can be utilized in somatic cells to repair DNA that has a double-stranded break. It is called homologous recombination. Once a double-stranded break occurs, nucleases 'digest' or eat away at the broken ends of DNA so that new DNA can be added, b...
Studies of the segregation of RFLPs within pedigrees indicate that a single obligatory crossover occurs between the XY in human male meiosis.33 The observation of MLH1 foci on little more than half the observed sex bivalents may be an indication of either the eccentric timing of recombination ...
