Today we started Chapter 11 and the basics of Mendelian Genetics. Key concepts and vocab discussed include:
Lamarkism
allele
loci
homologous chromosomes
homozygous dominant
homozygous recessive
heterozygous
geneotype
phenotype
Principle of Segregation
Principle of Independent Assortment
Test Cross
Punnet Square
Monohybrid cross
Carrier
P generation
F1 generation
F2 generation
Phew! That's quite a few words/concepts. The material we are starting now has a substantial amount of terms, so make sure you start to make flashcards (if you need them) sooner rather than later.
Homework: Read section 11.2 and take notes, you will have a reading quiz. Also, complete the vocab section (part 2) of the worksheet we did in class today.
The Roloff Family, stars of TLC's Little People, Big World have brought dwarfism (achondroplasia) to the big screen. Achondroplasia is a genetic disorder that is caused by a dominant allele. The parents are heterozyous for the trait, which is why some of their children are not affected by the by the disorder.
