Vocabulary #1
The process by which a cell reproduces itself used for growth, repair and reproduction.
Cell Division
The cells of the body (skin cells, bone cells) carry all of the genetic material.
Somatic Cells
The first part of interphase where the cell grows and performs its normal job.
G1
What is the correct order for Mitosis?
Prophase, Metaphase, Anaphase, Telophase
2 Homozygous Dominant parents will result in what type of offspring?
100% Homozygous Dominant offspring
Thread-like structures in the nucleus made of DNA that contain all of the genetic information.
Chromosomes
the allele that is always expressed if it is present.
Dominant
The final part of interphase where the cell prepares for mitosis.
G2
Structures that act like ropes to pull the sister chromatids to each end of the cells during mitosis.
Spindle Fibers
What are the offspring percentages for the following parents Genotypes. Tt Tt
25% TT
50% Tt
25% tt
The regular sequence of growth and division that cells go through.
Cell Cycle
two of the same allele. ex: HH or hh.
Homozygous
The middle part of interphase where the cell copies its DNA.
S Phase
How many Chromosomes result in each daughter cell?
identical or 46.
Explain Co-dominance
When both alleles are expressed.
Reproduction that only involves ONE parent and produces offspring that are genetically identical to the parent.
Asexual Reproduction
what is on the gene – the actual alleles.
Genotype
True or False, Interphase is the shortest part of a cells life?
False
In this phase the Nuclear envelope forms at each pole?
Telophase
Explain Incomplete Dominance.
when neither allele is expressed. A blend.
the actual variations of genes that occur on the DNA. (the letters) these cause the trait that is expressed.
Allelles
Having 3 copies of a chromosome.
Trisomy
Why do cells divide?
Maximum surface area to transport necessities into the cell and export waste from the cell
Repair damaged cells and replace dead cells
The final phase of the cell cycle where the cytoplasm divides and two separate daughter cells are formed.
Cytokinesis
Show a cross between a pure red-eyed female and a white-eyed male. Use the letters E & W
