Cell Reproduction test retake information:

If you failed the test, you have to retake it. If you passed, but wish to retake the test, you may. Before the retake you have to print and complete Ch. 12 Review 1, Ch. 12 Review 2 and Ch. 12 Review 3. and then talk to Mrs. Jankowski to schedule your retake.

Heredity

Chapter 13

Test Thursday 12-17

Science TEKS 7.14

Organisms and environments. The student knows that reproduction is a characteristic of living organisms and that the instructions for traits are governed in the genetic material. The student is expected to:

(A) define heredity as the passage of genetic instructions from one generation to the
next generation;

(B) compare the results of uniform or diverse offspring from sexual reproduction or asexual reproduction; and

(C) recognize that inherited traits of individuals are governed in the genetic material found in the genes within chromosomes.

Section 1: Genetics

Concepts:

• Genetics, heredity, traits
• Genes, alleles
• Mendelian inheritance
• Hybrids; dominant and recessive genes
• Punnet squares
• Genotype (homozygous, heterozygous) and phenotype

Answer show questions

Practice: p. 390 # 6, 7.

Section 2: Genetics since Mendel

Concepts:

• Incomplete dominance
• Multiple alleles, blood types
• Polygenic inheritance
• Mutations
• Recessive genetic disorders
• Sex determination
• Sex-linked disorders and pedigrees

Polygenic inheritance; mutations and chromosomal disorders; recessive genetic disorders

Section 3: Genetic Engineering

Concepts:

• Genetic engineering
• Recombinant DNA
• Gene therapy

Tuesday 12-8

Mrs. Jankowski is not here

When the above is completed, work on Genetic Engineering Internet activities: go to Learn Genetics and complete as many activities as you can, starting with "What is Gene Therapy".
