PLoS Genet 8:e1002847 PubMed CAS Article Google Scholar What one event in meiosis makes it possible for chromosomes in gametes to have new combinations of genes?When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome.
What causes new combinations of alleles in meiosis?Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles. This recombination process creates genetic diversity at the level of genes that reflects differences in the DNA sequences of different organisms.
Which step of meiosis generates combinations of alleles in the homologous chromosomes in your gametes that were not originally present?Prophase I: The homologous chromosomes line up together. During this time, a process that only happens in meiosis can occur. This process is called crossing over (Figure below), which is the exchange of DNA between homologous chromosomes. Crossing over forms new combinations of alleles on the resulting chromosome.
Which process results in the formation of new combinations of alleles in resulting gametes?Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
