Download ESSENTIAL CONCEPTS CLASS ACTIVITY 1: Polygenic Inheritance

meiosis is a reduction division of a diploid nucleus to
form haploid nuclei (4.2.1)
Define polygenic inheritance (10.3.1)
Meiosis (Basics)
Define homologous chromosomes (4.2.2)
CLASS ACTIVITY 1:
Polygenic Inheritance Model
Polygenic Inheritance
Human skin tone
Heredity and "classic genetics"
Explain that polygenic inheritance can contribute to
continuous variation (10.3.2)
outline the process of meiosis (4.2.3)
traits under the influence of natural selection
genotype
phenotype
Non-disjunction can lead to changes in chromosome number
(4.2.4)
State that eukaryotic chromosomes are made of
DNA and proteins (4.1.1.)
Karyotyping, chromosomes are arranged in pairs
according to size and structure (4.2.5)
Define gene, allele, and genome (4.1.2)
Definitions (4.3.1)
Basic Concepts
dominant allele
CLASS ACTIVITY 2:
Chromosocks 1:
Modeling Meiosis
Dihybrid crosses and gene linkage (10.2)
ESSENTIAL CONCEPTS
recessive allele
Recombination of alleles during meiosis
contributes to genetic variability within a
population
codominant alleles
Karyotyping is performed using cells collected by
C.V.S., or amniocentesis, for pre-natal screening of
chromosomal abnormalities (4.2.6)
Analyze a human karyotype to determine gender
and whether non-disjunction has occurred (4.2.7)
locus
Describe the behavior of chromosomes in the phases
of meiosis (10.1.1)
homozygous
Meiosis (HL)
heterozygous
Outline the formation of chiasmata in the process of
crossing over (10.1.2)
Explain how crossing over between non-sister
chromatids of a homologous pair in prophase I can
result in an exchange of alleles (10.2.3)
Theoretical Genetics (4.3) also known as Basic
Mendelian Genetics
determine the genotypes and phenotypes of
offspring from a monohybrid cross using Punnet
squares (aka Punnet grids) (4.3.2)
Explain how meiosis results in an infinite variety in
gametes through crossing over in prophase I, and
random orientation in metaphase I (10.1.3)
State that some traits result from more than two
alleles (Reardon: most traits….are polygenic) (4.3.3)
Describe ABO blood types as an example of
codominance and multiple alleles (4.3.4)
CLASS ACTIVITY 3:
Chromosocks 2:
Mendel & Meiosis
the X and Y chromosomes in humans
State Mendel's law of independent assortment (10.1.4)
Explain how sex chromosomes control gender (4.3.5)
Explain the relationship between Mendel's law of
independent assortment and meiosis (10.1.5)
State that some genes are on the X chromosome,
and absent on the shorter Y chromosome in humans
(4.3.6)
Here, the IBO means X-linkage
Define sex linkage (4.3.7)
Example 1: red-green color blindness
Example 2: hemophilia
State that human females can be homozygous or
heterozygous with respect to X-linked genes (4.3.9)
Explain that female carriers are heterozygous for Xlinked recessive alleles (4.3.10)
CLASS ACTIVITY 4:
Working genetics
problems
Predict genotypic and phenotypic frequencies of
monohybrid crosses any of the above patterns of
inheritance (4.3.11)
Deduce genotypes and phenotypes of individuals in
pedigree charts (4.3.12)
