Vocab (for homework, copy off of blog into your vocab section):
Phenotype - organism's observable traits (what you can see on the outside).
Genotype - individual's pair of alleles for a specific gene or group of genes that determines a trait (what's in the genes).
Dominant - version of gene that appears with only one copy of a version of a gene (an allele).
Recessive - hidden trait, that is, the genetic trait that is not observed in a heterogeneous individual.
heterozygous - an organism that has more than 1 kind of allele for a characteristic.
homozygous - an organism that has only one kind of allele for a characteristic.
Punnett Square - diagram to show the likelihood of each outcome of a breeding experiment with known parent genes for a trait. See p. D-37.
PLUS: if you were absent on Monday, you need to include the following Notes and Vocab from Monday's lesson:
Topic: What Are Your Genes? Investigating Human Traits
Obj: TSW collect data on six human characteristics and discuss causes of human variation.
Vocab from Monday's class:
o Allele - a variant or version of a gene. Ex: a gene could code for a round thumb joint, or a squared off thumb joint. One is Dominant (it wins), while the other is Recessive (it loses unless its the only one).
o Characteristic - an observable or measurable feature of an organism and may be caused by one gene or many genes. Ex: eye color.
o Gene - A specific sequence of DNA that determines one or more traits.
o Genetics - the study of the location and behavior of genes, their passage to offspring, and of how characteristics are inherited.
o Heredity - traits passed down to people or other organisms from their biological parents. Ex: eye color, tongue rolling, height potential, genetic diseases, arm span.
* Inherited - The passage of traits from parent to offspring.
