While conducting experiments on pea plants mendel observed that the combination of traits and the offspring did hot match up with the pare rents. how did mendel explain this

The alleles of the Offspring would be mixed with the parents. So if a parents allele was TT and anothers was Tt

it would be either TT or Tt.

Look up 'punnett square'. That's also how he explained it.

If you know about a punnett square already I dunno. I tried to answer it to the best of my abilities

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.
