Q

Pink snap dragons from red and white parents, neither allele is fully dominate

A

Incomplete dominance

17
Q

AB blood group, the A and B are expressed

A

Codominance

17
Q

ABO blood group, more than one type of allele controlling a trait

A

Multiple alleles

18
Q

2 alleles of a gene can mask another gene. Ex. Abinism

19
Q

Single gene pair has more then one effect or phenotypic expression in an individual, such as in Marfan syndrome

A

Pleiotrophy

20
Q

More than one gene pair controlling a trait and results in small differences of a bell-shaped curve

A

Polygenic Inheritance or continuous variation

21
Q

Process by which chromosomes fall to separate properly and abnormal numbers of chromosomes or Annueploidy can occur/ abnormal # of chromosomes

A

Nondisjunction

22
Q

Missing one chromosome would result in monosomy or monosomic cells

A

2n-1 or n-1

23
Having an extra chromosome would result in trisomy or trisomic cells
2n+1 n+1
24
XXY, make with extra X may have breast enlargement
Klienfelters
25
Male with extra Y, taller than average
XYY
26
Female missing an X
XO or turners
27
Female with extra X
XXX
28
Trisomy or downs syndrome
extra 21st chromosome
29
Missing a part
Deletion
30
Repeated section
Duplication
31
Take a piece out, rotate 180 and put it back
Inversion
32
Part of non-homologous chromosomes may have a mix up or exchange of genes/DNA for different traits
Transversion
33
An old idea prior to Mendel's work that we are a blend of our parents
Blending theory
34
Colorblindness and Hemophilia
Examples of sex-linked traits, carried on the X chromosome
