5.3 Mendelian Genetics

 

Learning Objective(s):

Explain the inheritance of genes and traits as described by Mendel’s laws.

#	Tasks:
1	Quiz: Meiosis and Sexual Reproduction   Complete the quiz!   Part B When available, complete the practical modeling.
2	Finish - Mendel’s Laws of Inheritance Try the sample problems in the blue packet from yesterday.
3	Mendel’s Laws of Inheritance You are to look up the three laws that govern Mendelian genetics
4	NOTES > Mendel’s Genetics   DNA and RNA are carriers of genetic information. Ribosomes are found in all forms of life. Major features of the genetic code are shared by all modern living systems. Core metabolic pathways are conserved across all currently recognized domains. Mendel’s laws of segregation and independent assortment can be applied to genes that are on different chromosomes. 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.
4	Exploring Heredity and Probability Students are to use Punnett squares to investigate patterns of Mendelian Inheritance.
5	Solutions Review – Exploring Heredity & Probability The whole class reviews the solutions for the problems on the worksheet.

5.2 Meiosis and Genetic Diversity continued

 

Today's Learning Objective(s):

Explain how the process of meiosis generates genetic diversity.

#	Tasks:
1	Quizlet Live - Meiosis Practice new vocabulary
2	Crash Course Biology
3	Meiosis Review Questions    You will receive review questions. Write responses to the questions.
4	NOTES > Genetic Diversity and Chromosome Variation Segregation, independent assortment of chromosomes, and fertilization result in genetic variation in populations. The chromosomal basis of inheritance provides an understanding of the pattern of transmission of genes from parent to offspring. Certain human genetic disorders can be attributed to the inheritance of a single affected or mutated allele or specific chromosomal changes, such as nondisjunction. 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.

5.2 Meiosis Genetic Diversity

 Today's Learning Objective(s):

Explain how the process of meiosis generates genetic diversity.

#	Tasks:
1	Quizlet Live - Meiosis Practice new vocabulary
2	Modeling Meiosis Use the model to show meiosis. How can they manipulate the pieces to show the various event that happen in meiosis.
3	NOTES > Meiosis   Meiosis is a process that ensures the formation of haploid gamete cells in sexually reproducing diploid organisms—a. Meiosis results in daughter cells with half the number of chromosomes of the parent cell. b. Meiosis involves two rounds of a sequential series of steps (meiosis I and meiosis II).   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.
