In horses, grey coat color is determined by a dominant allele. A herd of 50 horses is observed to have 20 grey horses. Determine each of the following values for this herd.

I think it'd be 30/20 which is a 3:2 ratio.

Explanation:

Gray is dominant, therefore a single copy of the gray allele will cause a horse to turn gray. If a horse has two copies of gray, all offspring of this horse will be gray.

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.
