Chapter 15 Vocab

Theory that states Mendelian genes have specific loci on chromosomes, and it is these chromosomes that undergo segregation and assortment

The phenotype for a character most commonly observed in natural populations

A gene located on either sex chromosome

Genes found of the human X chromosome

A human genetic disease cause by a sex-linked recessive allele and characterized by progressive weakening and loss of muscle tissue

X-liked recessive disorder defined by the absence of one or more of the proteins required for blood clotting

The inactive X in each cell of a female condenses into a compact object is known as this

Genes located near each other on the same chromosome tend to be inherited together in genetic crosses

The production of offspring with new combinations of traits, different from those found in the P generations

Matching one of the true-breeding parental phenotypes

A chromosome created when crossing over combines DNA from 2 parents

The reciprocal exchange of genetic material between non sister chromatids during prophase 1 of meiosis

An ordered list of the genetic loci along a particular chromosome

Genetic map based on the recombination frequencies

A unit of Measurement of the distance between genes, one map is equivalent to a 1% recombination frequency

When a pair of homologous chromosomes fail to move apart properly during meiosis 1, or when sister chromatids fail to separate in meiosis 2

The condition when the zygote has an abnormal number of a particular chromosome

Refers to a zygote with a chromosome missing

Refers to a zygote with a chromosome present in triplicate

Refers to when some organism have more than two complete chromosome sets in all somatic cells

When a chromosome fragment is lost

When a fragment from a chromosome is duplicated and fused with a homologous chromosome

When a fragment reattaches to the original chromosome in the reverse orientation

Segment attaches to a non-homologous chromosome

Genetic disease caused by the presence of an extra chromosome 21 and resulting in developmental delays, physical differences, and some heart issues

When variation in the phenotype is dependent upon whether an allele is inherited from the male or female present
