This image shows the arrangement of chromosomes of an individual
What is a karyotype
100
This is the number of daughter cells that results from one mitotic division
2 cells
100
Meiosis results in this number of gametes.
What are 4
100
This is an alternate version of the same gene. Every gene has one copy in each gamete.
What is an allele
100
In the genotype Ff, the F allele is this to the f allele.
What is dominant.
200
This chromosome is only found in male humans.
What is the Y chromosome
200
Chromosomes line up along the a central axis during this phase of mitosis.
What is metaphase
200
The number of divisions that must occur during meiosis.
What are 2
200
This is the location of a gene on a chromosome.
What is locus
200
This describes an individual with a genotype of RR or rr.
What is homozygous
300
Condition when a individual has three copies of chromosome 21.
What is Down Syndrome
300
Chromosomes must be duplicated in this stage before mitosis can begin.
What is interphase
300
The process is the physical exchange of chromosome pieces during prophase I of meiosis I
What is crossing over
300
The physical appearance of a gene.
What is phenotype
300
The genetic basis of a gene, written as Gg, for example.
What is genotype
400
Chromosomes are composed of this fiber, which is made up of DNA and proteins.
Chromatin
400
Cytokinesis in plant cells occurs by the formation of this.
What is the cell plate
400
This is the purpose of meiosis.
What is the production of egg or sperm.
400
A heterozygous individual for a recessive human disorder is considered to be this.
What is a carrier
400
The inheritance pattern in which many genes influence one trait, such as human height.
What is polygenic inheritance.
500
The total number of chromosomes in a diploid human cell.
What is 46 chromosomes.
500
In prophase, this must breakdown which allows the chromosomes to be separated in later phases.
What is the nuclear envelope
500
This happens when chromosomes fail to separate properly during meiosis I or meiosis II.
What is nondisjunction
500
This non-Mendelian inheritance pattern is seen when the phenotypes of the two homozygous individuals are blended together in the heterozygote. Red and white flowers produce pink.
What is incomplete dominance
500
This inheritance pattern is found with AB blood type in humans, where the phenotype of both alleles is expressed.
