During meiosis, what happens when chromosomes "cross over"? Group of answer choices chromosomes get twisted up and often do not separate equally chromatids swap reciprocal segments of DNA nothing, chromosomes do not cross over during meiosis homologous chromosomes do not pair

DRAW OUT CLEARLY each of these chromosomes labeling as appropriate (demoed in class) The cell has a diploid number of 8 Each pair has a set of linked genes that are located on each end of the chromosome (paternal on left, maternal on right) Pair 1 AB and ab Pair 2 DE and de Pair 3 Fg and fG Pair 4 hI and Hi Show what the chromosomes would look like in G1, G2, TI and TII

Recombination through independent assortment and crossing over can occur in which of the following? Mitosis Meiosis II Meiosis I All of the above

If crossing over occurs between two chromatids on a single pair of homologous chromosomes, how many gametes will have a recombinant phenotype? Multiple Choice   all 4   1 of the 4   2 of the 4   3 of the 4   none of them
