1
New cards
Phenylketonuria
\________ (PKU)- autosomal recessive disease caused by a single gene defect.
2
New cards
Karyotype
\________: a chart that organizes chromosomes in relation to number, size, and type.
3
New cards
Hemophilia
\________ caused by the absence of a protein vital to the clotting process.
4
New cards
Thomas Morgan
\________ made key discoveries regarding sex linkage and linked genes.
5
New cards
Crossover
\________- a form of genetic recombination that occurs during prophase I of meiosis, led to their production.
6
New cards
Tay Sachs
\________ disease- fatal genetic disorder that renders the body unable to break down a particular type of lipid that accumulates in the brain and eventually causes blindness and brain damage.
7
New cards
Edwards
\________ syndrome- can affect all organs; trisomy 18.
8
New cards
Anaphase I
\________- Separated homologous pairs move to opposite poles of the cell.
9
New cards
Geneticists
\________ breed the organism whose genotype is unknown with an organism that is homozygous recessive for the trait.
10
New cards
Intermediate inheritance
\________- an individual heterozygous for a trait (Yy) shows characteristics not exactly like either parent.
11
New cards
Cytokinesis
\________- After the daughter cells split, the two newly formed cells are haploid (n)
12
New cards
Huntington
\________ disease- A fatal disease that causes the breakdown of the nervous system.
13
New cards
human life
The cells produced during meiosis in the \________ cycle- gametes.
14
New cards
mates
A horizontal line from male to female represents \________ that have produced offspring.
15
New cards
Cystic fibrosis
\________ (CF)- recessive disorder, the most common fatal genetic disease in the US.
16
New cards
Haploid
\________ (n) organism- Has only one copy of each type of chromosome.
17
New cards
Genotype
\________: an organisms genetic makeup for a given trait.
18
New cards
Diploid
\________ (2n) organism- Has two copies of each type of chromosome.
19
New cards
Chromosome duplication
\________- results in the repetition of a genetic segment.
20
New cards
genetic information
After meiosis I in females, one cell receives half the \________ and the majority of the cytoplasm of the parent cell.
21
New cards
genetic input
The phenotype is a "mixture "of both of the parents \________.
22
New cards
Mendel
\________ used plant experiments to test this hypothesis and developed his two fundamental theories: the law of segregation and the law of independent assortment.
23
New cards
F2
\________: the second generation of offspring, or the second "filial "generation in a genetic cross.
24
New cards
Deletion
\________- occurs when a piece of the chromosome is lost in the developmental process.
25
New cards
F1
\________: the first generation of offspring, or the first "filial "generation in a genetic cross.
26
New cards
Chronic myelogenous leukemia a cancer
\________ affecting white blood cell precursor cells.
27
New cards
DNA
Non- nuclear inheritance, in which offspring get \________ only from the male or female parent, does not follow the Mendelian pattern of inheritance.
28
New cards
Eg
\________: Mendels peas- round or wrinkled, green or yellow, purple flower or white flower.
29
New cards
Meiosis
\________ consists of a single synthesis period during which the DNA is replicated, followed by two acts of cell division.
30
New cards
Turner syndrome
\________ (XO)- sterile females who possess sex organs that fail to mature at puberty.
31
New cards
Gregor Mendel
\________- spent many years working with peas.
32
New cards
P1
\________: the parent generation in a genetic cross.
33
New cards
Nondisjunction
\________: the improper separation of chromosomes during meiosis, which leads to an abnormal number of chromosomes in offspring.
34
New cards
Patau syndrome
\________- causes serious brain and circulatory defects; trisomy 13.
35
New cards
Dihybrid
\________ cross- the crossing of two different hybrid characters (BbRr Ă— BbRr)
36
New cards
Telophase II
\________- The nuclei and the nucleoli for the newly split cells return.
37
New cards
excess cytoplasm
The \________ is required for proper growth of the embryo after fertilization.
38
New cards
Gregor Mendels work
\________- not able to account for many patterns of inheritance that occur in life (sex- linked traits, incomplete dominance, and codominance)
39
New cards
Usage of pedigrees
\________: determine the risk of parents passing certain conditions to their offspring.
40
New cards
Allele
\________: a variant of a gene for a particular character.
41
New cards
Phenotype
\________: the physical expression of the trait associated with a particular genotype.
42
New cards
Phenotype of an organism
\________- can be determined from simple observation.
43
New cards
fruit flies
The \________ had four pairs of chromosomes: three autosomal pairs and one sex chromosome pair.
44
New cards
monohybrid cross
A(n) \________ between heterozygous gametes gives a 3: 1 phenotype ratio in the offspring.
