How would you create a fertile plant after crossing two species of plants with different numbers of chromosomes? [For example, cross wheat (24 chromosomes) with a wild grass (31 chromosomes)]. allow the plant to go through meiosis and produce seeds induce nondisjunction of its chromosomes during mitosis a fertile plant cannot be created

Adams maternal and paternal chromosomes have alternate forms of a gene that influences whether a person is right-handed or left-handed. One form says right and its partner says left. Visualize one of Adams spermatogonia, in which chromosomes are being duplicated prior to meiosis. Visualize what happens to the chromosomes during anaphase I and II. (It might help to use toothpicks as models of the sister chromatids of each chromosome.) What fraction of Adam's sperm will carry the gene for right-handedness? For left-handedness?
