Answer:
Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.
Explanation:
When chromatids "cross over," homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.
Answer:
Use chemicals to prevent chromosomal separation during meiosis in plants.
Answer:
Wingless offspring
Explanation:
Complementation is the terminology used for finding difference in the mutation of same or different gene.
Two groups with same complementation have failed to complement each other.
Thus, two wingless flies will have the same genotype i.e “ww”
When two wingless flies are crossed following offspring are produced
ww * ww
ww, ww, ww, ww
All the offspring are wingless too
