Webbed Fingers or Toes (Syndactyly). Webbed fingers and toes, formally called syndactyly, is a condition that occurs when two or more fingers or toes are fused together by skin.In rare cases, the fingers or toes could be joined together by bone, blood vessels, muscles, or nerves. This condition is present at birth.ebbed Fingers or Toes (Syndactyly).

n. 1. The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell. 2.
This is called the interphase. Just before cell division, the chromosomes are duplicated. This is called the S phase. Then mitosis occurs. To facilitate separation of DNA, the chromosomes condense and become visible under light microscopy.Only during the M phase (mitosis) chromosomes are visible.uring interphase, the cell is essentially preparing for mitosis. Thus, the nuclear membrane is still intact. The cell is merely replicating its DNA and chromosomes. During mitosis itself, however, the nuclear membrane breaks down so the chromosomes become visible under a microscope.
