Structures in the cell containing genetic material, 46 in total, organized in 23 pairs.

The molecule that contains the genetic code for living organisms; the blueprint for life.

Segments of DNA that code for proteins, typically numbering between 20,000 and 25,000.

The membrane-bound organelle in a cell that contains chromosomes and controls genetic information.

The estimated total of genes in a human is between 20,000 to 25,000.

Different forms of a gene; e.g., B and b for eye color.

An allele that masks the effect of a recessive allele; e.g., B for brown eyes.

An allele that is masked by a dominant allele; e.g., b for blue eyes.

A genotype with two identical alleles; either BB or bb.

A genotype with one dominant and one recessive allele; Bb.

Interaction where dominant traits mask recessive traits; examples include a Roman nose and curly hair.

A blending of traits where neither allele is completely dominant; hazel eyes are an example.

Traits influenced by multiple genes, such as height and skin color, resulting in a range of variations.

Traits influenced by both genes and environmental factors; spina bifida is an example.

Traits determined by genes located on the X chromosome, including color blindness and hemophilia.

The genetic makeup or instructions of an organism.

The observable traits or characteristics of an organism.

A table used to predict genetic combinations from parents' alleles.

The specific pairing of alleles inherited from each parent.

The probability ratio of offspring characteristics from parents; typically 1:4 in a Punnett square.

A mode of inheritance where genes on the X chromosome are involved, affecting males and females differently.

The colors representing different traits in a pedigree chart: green (normal), red/brown (carrier), and red (affected).

An individual with a red/brown phenotype who can pass on the trait but is not affected themselves.

A visual representation of inheritance patterns over generations in a family.

The X chromosome influences trait expression; males have one X, females have two, affecting how traits manifest.

A genetic disorder caused by having 47 chromosomes, leading to distinctive features and developmental delays.

A condition in males with an XXY chromosome pattern, resulting in infertility and psychological issues.

A chromosomal disorder in females with one X missing, leading to lack of secondary sex traits and infertility.

A blood disorder caused by sickle-shaped red blood cells, leading to pain and anemia, mainly in African-Americans.

A genetic disorder where the body cannot break down phenylalanine, resulting in intellectual delays; treatable with diet.

Common physical traits of Turner Syndrome include short stature, low hairline, and shield-shaped thorax.

Internal characteristics can include rudimentary ovaries, no menstruation, and constriction of the aorta.

One of the most noticeable features of Turner Syndrome, leading to shorter-than-average height.

Underdeveloped gonadal structures in Turner Syndrome, indicating immature ovaries.

The visual representation showing the presence of 47 chromosomes, including two X chromosomes and one Y chromosome.

Common features include breast development and hypogonadism in affected males.

The 22 pairs of chromosomes in humans that are not sex chromosomes.

The X and Y chromosomes that determine the biological sex of an individual.

The condition where an individual has three copies of chromosome 21 instead of the usual two.

A visual representation of an individual's chromosomes, showing number and structure.

The chromosome that, when present in three copies, leads to Down's syndrome.

A mutation or defect in the genetic material that can lead to disorders like Down's syndrome.
