In elephants, the allele for small tusks (T) is dominant to the allele for large tusks (t). The allele for a long nose (N) is dominant to the allele for a short nose (n). A bull elephant that is heterozygous for both traits can produce unique gametes containing which allele combinations?

Tt,TN,NT,tn,nt,Nt,tN,Tn,nT

Explanation:

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
