homologous | paired chromosomes the form a tetrad during prophase 1
🗑
|
||||
crossing-over | parts of homologous chromosomes exchange information and leads to genetic variation (difference)
🗑
|
||||
diploid | 2 sets of chromosomes represented by 2N found in somatic cells
🗑
|
||||
haploid | 1 set of chromosomes represented by 1N or N found in gamete cells
🗑
|
||||
somatic cells | body cells
🗑
|
||||
meiosis | process of reduction division in which the chromosome number is cut in half through 2 cell divisions
🗑
|
||||
Prophase 1 | crossing-over occurs
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
