Heterochromatin
The coding regions of a gene the portions that are expressed as polypeptide sequences are called?
exon
What is a process in which homologous chromosomes exchange portions of their chromatids during meiosis?
the process in which homologous chromosomes exchange portions of their chromatids during meiosis is the definition of the term "Crossing Over"
What happens in the tetrad stage?
During the tetrad stage, the metaphase I of meiosis starts to happen. When this occurs, the diploid meiocyte divides twice.

Are exposons the portions of DNA molecules that code for the production of proteins?
Exons are what are expressed while introns are spliced out.
What is homologous chromosomes frequently exchange portions of their DNA called?
It's called crossing over, and it generally only happens between homologous chromosomes.
What do chromosome contain?
Chromosomes contain genes, regulatory portions, the centromere, the telomere and "junk DNA".
The diagram below illustrates which type of chromosomes that may cross over and exchange portions of their chromatids during meiosis?
what type of cell has two sets of chromosomes
What crosses over during crossing over?
Each chromatid can synapse with any one it want/chooses.
Are alleles made up of DNA?
All alleles contain DNA. They are the genes. An allele is one form of a gene. For example, the gene for flower color in pea plants has two alleles, one for purple flower color, and one for white flower color.
Which is better Counting Calories or Counting Portions?
