(a.ii.1.b)
Achondroplasia: a ___________ condition: dwarfism
(a.ii.2)
Polygenic inheritance: (facts)
(a.ii.2.a)
Quantitative characters are those that wary in the population along
a continuum.
(a.ii.2.b)
Quantitative variation usually indicates polygenic inheritance, an
additive effect of two or more genes on a single phenotype
(a.ii.2.c)

____________
(a.ii.3)
Mendelian inheritance has its physical basis in the behavior of
____________
(a.ii.3.a)
Chromosome theory of inheritance:
(a.ii.3.a.i)
Mendelian genes reside at specific locations (_____) on
chromosomes
(a.ii.3.a.ii) Chromosomes undergo segregation and independent assortment
a.ii.3.a.ii.1.
________ ____ _________: provided first evidence that
Mendel’s heritable factors were on chromosomes.
a.ii.3.a.ii.2.
Morgan’s experimental organism were_______ ________.
a.ii.3.a.ii.3.
Characteristics:
a.ii.3.a.ii.3.a.
a.ii.3.a.ii.3.b.
a.ii.3.a.ii.3.c.
Easily visible phenotypes
a.ii.3.a.ii.3.c.i. P generation female flies with red eyes x male flies
with white eyes
a.ii.3.a.ii.3.c.ii.F1 generation all had _____ eyes
a.ii.3.a.ii.3.c.iii.
F2 generation: _____ratio red: white, but
only ________ had white eyes.
(a.ii.3.a.iii)Association of specific gene and chromosome:
a.ii.3.a.iii.1.
Morgan reasoned that the gene for eye must be located on
the _____(X/Y) chromosome, since white recessive trait only appeared
in males.
