Gold Tape Question: This week's Gold Tape question is worth two pieces of Gold Tape! Turn in your work on Monday or send a picture of it to firstname.lastname@example.org
Question: In Sponges Yellow (Y) is dominant to blue (y) and Square (S) is dominant to round (s). SpongeBob is heterozygous for his yellow color and square shape (YySs) and SpongeSusie is heterozygous for her yellow color and round (Yyss). Use a dihybrid cross to determine the phenotype and genotype percent (or ratio) possibilities of all offspring.
In class today we finished our origami genes and also added to our genetics vocabulary list. Understanding the language of genetics is essential to being able to really understand how genetics work and make predictions about the genetic make up of organisms. Here are the words we added today.
Hybrid: Offspring receiving different alleles from each parent
Dominant: The form of an allele that covers up the other form of an allele
Recessive: The form of an allele that is covered up by the dominant allele
Genotype: refers to the genetics make up of an organism (represented by pairs of letters TT, Tt, tt)
Phenotype: The physical traits of an organism, more simply what an organism looks like (Tall, short)
Homozygous: a pair of alleles that are the same AA, aa, BB, bb
Heterozygous: When a pair of alleles are different Aa, Bb, Cc
Gold Tape Question: Where was George Beadle born and what is his famous scientific discovery that has to do with genes?
We continued adding to our genetics notes today with special emphasis on DNA. We also watched a short video and began our origami DNA molecules.
In class today we finished our "Genes in my Body" Diagram and continued our exploration of genetics.
Also, if you didn't do as well on the back page (meiosis section) of the quiz. An alternate assignment is at the bottom of this post for you try try again.
Meiosis Alternate Assignment: Watch the video below and answer the following questions. You can turn them in to Mr.Powell in class or email them to email@example.com
In class students took a short quiz over their understanding of genetics thus far based on our dragon breeding activity. Then we began creating our notes for the rest of the unit.
Although we are done breeding dragons in class, your journey does not have to be over! I encourage you to continue breeding dragons at home. The link to the Geniverse Lab is posted on the Genetics page of this website. Good Luck!
GOLD TAPE QUESTION: Email Mr. Powell (firstname.lastname@example.org) the answer to the following question; What is the difference between a gene and an allele?
Mr. Powell is an 8th grade Science Teacher in Western Colorado.
