The diagram shows a cell undergoing meiosis. Correctly label the diagram by dragging and dropping each label to the arrow indicating that particular structure. Kinetochore Centrosome Sister chromatid H Spindle fibre Chiasma Pair of homologous chromosomes

mitosis nuclei resides in the nucleus karyotype autosomes haploid In dividing parent cell; in the parent cell. Male and female gametes at fertilization forms a homologs Microscopic observations showed that during fertilization, the unite, providing evidence that genetic material resides in the cell membrane Brightly staining, threadlike bodies within the nucleus were termed of these bodies could be traced through cell division. chromosomes diploid A image can reveal abnormalities in meiosis of eggs and sperm ; the movements gametes contain a single set of chromosomes. The fusion of zygote. the number of chromosomes in daughter cells remains the same as in the the number of chromosomes in daughter cells is half that of Two chromosomes that match in size, shape, and banding when isolated and stained are is an image of an individual's chromosomes arranged in homologous pairs. This chromosome number and structure nondisjunction

Consider a diploid somatic cell with 3 unique autosomes and no sex chromosomes. At mitotic metaphase this cell will have ___ chromosomes, ___ double helix molecules, ___ tetrads (bivalents), and ___ sister chromatid pairs.

AC elegans cell has 6 pairs of chromosomes in G1. What is the total number of chromatids present in the cell at the end of anaphase Il of meiosis? O 12 O 3 O 24 O o o 0

Mitosis is used to make more body cells while meiosis is only used to make gametes for sexual reproduction. What would be a problem if an organism tried to use mitosis for sexual reproduction instead of meiosis? Mitosis Parent cell Meiosis Parent cell DNA replicates DNA replicates 2 daughter cells 2 daughter cells 4 daughter cells U.S. National Library of Medicine (Level 3) étv МacBook Air DII DD 80 888 F7 F8 F9 F10 F4 F5 F6 F2 F3 23 $ & 3 4 9. 7 8 9 Y F H J K L C V M B E
