What is phenotype?
100
simply a picture of a persons chromosome
What is a karyotype?
100
A chromosome is a structure composed of DNA and found in the nucleus(X-like structure)
What is a chromosome?
200
When cells lose the ability to control cell growth
What is cancer?

What are homologous chromosomes?
200
A persons genetic make-up
What is genotype?
200
development disorder caused by an extra copy of chromosome 21
What is Down syndrome?
200

What is a chromatid?
300
In prophase the chromosomes become visible. The centrioles start moving to the opposite sides of the nucleus.
What what happens in the first phase of mitosis?
300
4 cells are produced at the end of meiosis and they all are genetically different.
How many cells are produced at the end of meiosis? Are they all identical?
300
Represented by lower case letters and shows up in phenotype when paired with another recessive allele
What is a recessive allele?
300
tells us whether or not they have a chromosomal disorder. Also tells us if they are male or female.
purpose of karyotypes?
300
where the chromatids are attached(center of the chromosome)
What is a centromere?
400
to replace old cells or to help us heal.
Purpose of Mitosis?
400
prophase 1- The tedrads are formed and crossing-over happens
What is the first stage of meiosis?
400
intermediate inheritance in which one allele for a specific trait is not completely dominant over the other allele (combined phenotype)
What is incomplete dominance?
400
produces egg or sperm cell that don't have a normal amount of chromosomes
What is non-disjunction?
400
In the nucleus
Where are chromosomes located?
500
Metaphase is when the chromosomes line up ion the middle of the cell
What is the second phase of mitosis?
500
A tetrad is when a chromosome from the father and a chromosome from the mother are on top of eachother
What is a tetrad?
500
When 2 alleles are dominant and are expressed in phenotype
What is codominace?
500
When the 5th chromosome is missing.
