Variations on Mendel's Principles

Today students had a reading quiz on section 11.3 and we learned about variations on Mendel's principles.

There is a substantial amount of vocabulary in this chapter and in order to successfully solve the problems, you need to be able to understand the questions. Below is a list of the vocab and concepts we have covered so far.




homologous chromosomes
gene
allele
gene locus (loci)
geneotype
phenotype
Autosomal dominant disorder
Incomplete dominance
Heterozygous
Test Cross
Monohybrid cross
Dominant
Law of Segregation
Law of Independent Assortment
P, F1, F2 etc. generations
Pleiotropy
Recessive
Pedigree chart
Codominance
Autosomal recessive disorder
Homozygous
Genotypic Ratio
Polygenic trait
Carrier
Sex-linked traits
Genetic Disorders
Chorionic Villus Sampling
Achondroplasia
Probability
Phenotypic Ratio

On Friday we will be starting Meiosis and learning more about crossing over and the importance of genetic variation. On Monday we will do a 'dry lab' and make baby dragons.

Since you have already had to read section 11.4, there is no homework for Friday. However, you would benefit from re-reading the section if you were confused.
