What are chromosomes that have similar genetic information called?
Chromosomes that are similar are called homologous chromosomes. Chromosomes that have similar paired genes are called homolegous chromosomes. These copies have the same loci. These loci provide points along each chromosome that enable a pair of chromosomes to align.
What phase does chromatids line up along the equater?
Metaphase II In Metaphase I, the tetrads of homologous chromosomes line up along the equator, but they are not individual chromosomes.
In what phase of meiosis does chromosomes line up along equator not in homologous pairs?
AnaPhase1
What is a pair of homologous chromosomes in meiosis?
synapsis
How does independent orientation of chromosome during meiosis increase genetic variation?
Independent orientation of chromosomes refers to the allignment of the homologous chromosomes along the metaphase plate in metaphase I of meiosis. As the pair of chromosomes line up, one inherited from your mother and the other from your father, there are two orientation possibilities of equal probability; each pole has a 50% chance of inheriting one or the other. This is best explained using the sex chromosomes. Males are XY and females are XX. To differentiate these two female X chromsomes, we will call them Xa and Xb. In Metaphase I of meiosis, the chromosomes can be lined up along the metaphase plate (represented as l) as follows: Male: X l Y or Y l X Female: Xa l Xb or Xb l Xa

What is a sentence with metaphase in it?
At the stage of metaphase, chromosomes line up along the equator of the cell. Homologous chromosomes pair up.
What phase does chromatids line up along the equater?
Metaphase II In Metaphase I, the tetrads of homologous chromosomes line up along the equator, but they are not individual chromosomes.
In what phase of meiosis does chromosomes line up along equator not in homologous pairs?
AnaPhase1
What chromosomes align single file along the equator of a haploid cell?
during the metaphase. and they are called sister chromatids, not double chromosomes
Chromosomes line up along in the equator not in homologous pairs?
Metaphase. What's the difference? Whether it's IN homologous or NOT, they're both Metaphase..... Stupid worksheet. I hate you group 3. :(
What phase of meiosis do homologous chromosomes cross over?
Crossing over begins early in prophase I of meiosis. At the time, homologous chromosomes Are paired along their lengths. Each gene on one homologue ia alined precisely with the corresponding gene on the other homologue. Source: my science book copy right 2006
What is the area in which homologous chromosomes are joined?
If you mean the area of the cell, then they line up along the Metaphase (or equatorial) plate before being pulled apart. Or perhaps you mean the centromere - the bit that connects two homologous pairs?
What is the name given to the points along the length of homologous chromosomes where they remain held together in metaphase 1 just before their complete separation?
Centrioles
What is a pair of homologous chromosomes in meiosis?
synapsis
Chromosomes that contain genes that will determine the sex of an individual are called?
XX=female XY=male the male's second allele determines the sex (gender) of the offspring. If it is a Y, congratulations you're having a boy. If it is an X, you're having a girl. The sex linked genes are always carried along the X chromosome. The female's chromosome is always XX.
Do gametes have two sets of chromosomes?
No. a normal cell is diploid(2n) number of chromosomes. a normal human cell has 23 pairs of homologous chromosomes which makes 46 chromosomes. during meiosis 1 the homologous chromosomes randomly segregate along the equator and seperature into 2 daughter cells. during meiosis 2, the sister chromatids of the chromosome split in both of the daughter cell creating 4 daughter cells containign haplod (n) number of chromosomes - in humans they will have 23 chromosomes. gamete need to have half the number of chromosomes to a normal cell as when it fuses with another gamete during fertilization, the orginial 46 chromosome - diploid number will be restored.
