Homework for today:

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:

DAte:  1/26/15

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.
