LO/EK description  
  I have inlcuded the learning targets below highlighted in orange in my unit on cell division  
IST 1.F Explain how meiosis results in the transmission of chromosomes from one generation to the next.  
IST 1.F.1 Meiosis is a process that ensures the formation of haploid gamete cells in sexually reproducing diploid organisms Modeling Mitosis/Meiosis with Pop beads
IST 1.G Describe similarities and/ or differences between the phases and outcomes of mitosis and meiosis.  
IST 1.G.1 Mitosis and meiosis are similar in the way chromosomes segregate but differ in the number of cells produced and the genetic content of the daughter cells. Modeling Mitosis/Meiosis with Pop beads
Mitosis/Meiosis Comparison
IST 1.H Explain how the process of meiosis generates genetic diversity  
IST 1.H.1 Separation of the homologous chromosomes in meiosis I ensures that each gamete receives a haploid (1n) set of chromosomes that comprises both maternal and paternal chromosomes.  Modeling Mitosis/Meiosis with Pop beads
IST 1.H.2 During meiosis I, homologous chromatids exchange genetic material via a process called “crossing over” (recombination), which increases genetic diversity among the resultant gametes.  Crossing over, linked genes, & Gene mapping video
BILL genetic variation 
IST 1.H.3 Sexual reproduction in eukaryotes involving gamete formation—including crossing over, the random assortment of chromosomes during meiosis, and subsequent fertilization of gametes—serves to increase variation. Crossing over, linked genes, & Gene mapping video
BILL genetic variation 
EVO 2.A Explain how shared, conserved, fundamental processes and features support the concept of common ancestry for all organisms.  
EVO 2.A.1 DNA and RNA are carriers of genetic information.  
EVO 2.A.2 Ribosomes are found in all forms of life.  
EVO 2,A,3 Major features of the genetic code are shared by all modern living systems.
EVO 2.A.4 Core metabolic pathways are conserved across all currently recognized domains.  
ST 1.I Explain the inheritance of genes and traits as described by Mendel’s laws.  
  1.I.1 Mendel’s laws of segregation and independent assortment can be applied to genes that are on different chromosomes.  
  1.I.2 Fertilization involves the fusion of two haploid gametes, restoring the diploid number of chromosomes and increasing genetic variation in populations by creating new combinations of alleles in the zygote—
   a. Rules of probability can be applied to analyze passage of single-gene traits from
        parent to offspring.
   b. The pattern of inheritance (monohybrid, dihybrid, sex-linked, and genetically linked
         genes) can often be predicted from data, including pedigree, that give the parent
         genotype/phenotype and the offspring genotypes/phenotypes.

Non-Mendelian crosses
IST 1.J Explain deviations from Mendel’s model of the inheritance of traits.  
IST 1.J.1 Patterns of inheritance of many traits do not follow ratios predicted by Mendel’s laws and can be identified by quantitative analysis, where observed phenotypic ratios statistically differ from the predicted ratios—
    a. Genes that are adjacent and close to one another on the same chromosome may 
       appear to be genetically linked; the probability that genetically linked genes will
       segregate as a unit can be used to calculate the map distance between them.

IST 1.J.2 Some traits are determined by genes on sex chromosomes and are known as sexlinked traits. The pattern of inheritance of sex-linked traits can often be predicted from data, including pedigree, indicating the parent genotype/phenotype and the offspring genotypes/phenotypes  
IST 1.J.3 Many traits are the product of multiple genes and/or physiological processes acting in combination; these traits therefore do not segregate in Mendelian patterns.  
IST 1.J.4 Some traits result from non-nuclear inheritance—
a. Chloroplasts and mitochondria are randomly assorted to gametes and daughter cells;  thus, traits determined by chloroplast and mitochondrial DNA do not follow simple Mendelian rules.
b. In animals, mitochondria are transmitted by the egg and not by sperm; as such, traits  determined by the mitochondrial DNA are maternally inherited.
c. In plants, mitochondria and chloroplasts are transmitted in the ovule and not in the pollen; as such, mitochondria-determined and chloroplast-determined traits are maternally inherited.

SYI 3.B Explain how the same genotype can result in multiple phenotypes under different environmental conditions.  
SYI 3.B.1 Environmental factors influence gene expression and can lead to phenotypic plasticity. Phenotypic plasticity occurs when individuals with the same genotype exhibit different phenotypes in different environments. It's OK to be SMART- Epigenetics

  3.C Explain how chromosomal inheritance generates genetic variation in sexual reproduction.  
  3.C.1 Segregation, independent assortment of chromosomes, and fertilization result in genetic variation in populations. BILL genetic variation 
  3.C.2 The chromosomal basis of inheritance provides an understanding of the pattern of transmission of genes from parent to offspring.  
  3.C.3 Certain human genetic disorders can be attributed to the inheritance of a single affected or mutated allele or specific chromosomal changes, such as nondisjunction.
