Definition
The term for two identical chromosomes with the same set of genes and characteristics are known
What are homologous chromosomes?
The chromosomes become visible, crossing-over occurs, the nucleolus disappears, the meiosis spindle forms, and the nuclear envelope disappears.
What is prophase 1?
Chromosomes attach to spindle fibers
What is metaphase?
One half of the duplicated chromosomes
What are sister chromatids?
Process in the embryo starts to form
What is embryogenesis?
The fancy name for the reproduction cells
What is a gamete?
Homologous chromosomes bind together and share genetic information from maternal and paternal genes
What is crossing over?
Spindle fibers pull apart to opposite poles
What is anaphase?
Body cells with 46 chromosomes and 92 chromatids?
What is a somatic cell?
Process in which the fetus starts to take shape
What is morphogenesis?
Cells with half the number of chromosomes as the cell.
What are haploid cells?
The homologous chromosomes separate but the sister chromatids stay attached
What is anaphase 1?
The cytoplasm is split into two
What is cytokines?
A cell with 46 chromosomes
What are zygote cells?
The organization of a human cell’s total genetic complement.
What is a karyotype?
A membrane that separates the cytoplasmic and nucleus in eukaryotic cells
What is a nuclear membrane?
The chromosomes line up in a SINGLE file line in the middle of the cell
What is metaphase 2?
Chromosomes move to opposite sides of the cell and two nuclei are formed
What is telophase?
Found in male/females and represents approximately 5 percent of the total DNA in cells.
What are X chromosomes?
The set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Identical cells that are created after the parent cell divides
What are daughter cellls?
The diploid cells start to separate into haploid cells with HALF as much chromosomes as the original cell.
What is telophase 2?
Chromosomes form and nuclei disappears
What is prophase?
Creates a gene call SRY and normal sperm production
What are Y chromosomes?
The genetic constitution of an individual organism.
What is a genotype?
