If the image represents a meiotic cell, what will happen to the DNA represented in Box 1 after meiosis is complete? а. It will be split equally between the four daughter cells. Ob. It will be split between two of the four daughter cells, with different amounts of DNA in each cell. O c. It will be split between two of the four daughter cells, with the same amounts of DNA in each cell. d It will all end up in one daughter cell.

Rice has a chromosome number of 2n = 24.  If different euploids and aneuploids are available in rice,  identify the chromosomal mutation, chromosome configuration, chromosome number, and/or type of gametes in each of the mutations below. Example: For 10B, the answer is  “10 II + 2 I”

describe a specific example of chromosome abnormality that leads to human cancers, such as leukemia, other than the Philadelphia chromosome that is derived from the translocation of chromosome 9 and 22

Construct a map of the chromosome from the following recombination frequencies between individual pairs of genes: c – f 8%, v – f 12%, s – v 16%, v – c 4%, s – f 6%

The following diagram represents two nonhomologous chromosomes: A B • C D E F G R S • T U V W X What type of chromosome mutation would produce each of the following groups of chromosomes? a. A B • C D R S • T U V W X E F G b. A U V B • C D E F G R S • T W X c. A B • T U V F G R S • C D E W X d. A B • C W G R S • T U V D E F X

When stained with Giemsa (G-Banding staining), the centromere will be stained:   Question 28 options:   more robustly (dark band)   less robustly (light band)

Which of the following chromosome rearrangement genotypes and/or processes involving the described chromosome rearrangement can lead to unbalanced gametes? (Select all correct answers.) .00000 translocation heterozygote recombination outside of the inversion loop formed in a pericentric inversion heterozygote translocation homozygote pericentric inversion homozygote recombination within an inversion loop formed in a paracentric inversion heterozygote

A line of mouse cells is grown for many generations in a medium with 15N. Cells in G1 are then switched to a new medium that contains 14N. Draw a pair of homologous chromosomes from these cells at the following stages, showing the two strands of DNA molecules found in the chromosomes. Use different colors to represent strands with 14N and 15N. Q. Cells in anaphase II of meiosis, after switching to medium with 14N
