What You Need to Know for the Genetics Test

Mendel (p. 556) Who was he? What did he contribute to the field genetics? Specifically, what did he discover? Make sure you know the correct format for writing alleles in genetics crosses

Who was he?

What did he contribute to the field genetics? Specifically, what did he discover?

Make sure you know the correct format for writing alleles in genetics crosses

Genetic Material Make sure you know the difference between DNA, chromosomes, genes, alleles What are homologous pairs? Where do we get them? How are they the same? Different?

What are homologous pairs? Where do we get them? How are they the same? Different?

 

Mitosis and Meiosis What is the end product of mitosis? What is the purpose of mitosis? What is the end product of meiosis? What is the purpose of meiosis? Be able to explain how genetic material is transferred cell to cell, parent to offspring.

What is the end product of mitosis? What is the purpose of mitosis?

What is the end product of meiosis? What is the purpose of meiosis?

Be able to explain how genetic material is transferred cell to cell, parent to offspring.

 

Comparison of Mitosis and Meiosis Characteristic Mitosis Meiosis Number of daughter cells 2 4 Number of cell division(s) 1 2 Daughter cells are diploid or haploid Diploid Haploid Daughter cells are identical or different Identical Different Parent cell is diploid or haploid Diploid Diploid

 

Human Karyotype

Predicting Genetic Outcomes As a result of meiosis, human gametes have only half the number of body cells. Why is this important? Punnett Square Practice – monohybrid(one trait) crosses What is the outcome of this cross?

Punnett Square Practice – monohybrid(one trait) crosses

Protein Synthesis

Multiple Alleles Know examples of traits with multiple alleles and examples of traits with only two alleles. Be able to complete Punnett squares for both.

Sex Inheritance and Sex-Linked Genes What determines the sex of a child? What are the genotypes that determine sex? Why are males more likely to have sex-linked traits?

What determines the sex of a child? What are the genotypes that determine sex?

Why are males more likely to have sex-linked traits?

Sex-Related Trait Regular Trait

Pedigrees Be able to drawn and interpret pedigrees. Be able to determine if a pedigree is tracking a regular recessive trait or sex-linked trait.
