Week 7 Flashcards
What does ATP stand for?
Adenosine Triphosphate
What are some functions of ATP?
produces 95% of our energy
creates heat in the body
What is a Terminal Bond?
last bond to hold energy
when broken it releases heat
When ATP is broken 1 time what is it called?
Adenosine Diphosphate
When ATP is broken 2 times what is it called?
Adenosine Monophosphate
Who is the father of genetics?
Gregor Mendel
What are traits?
Hereditary physical characteristics known as genes
What is a gene?
Segment of chromosome that codes for a particular physical trait
What is Locus?
The position of the gene
(location)
What is an Allele
the alternate form of a gene
(Tall - Short)
*What are the 2 forms of Allele’s*
Dominate
Resessive
What is a Dominate Allele
Allways expressed
What is a Resessive Allele
not expressed if dominate is present
How do dominate and resessive allele’s occure?
Dominate in pairs or with a resessive allele
*What is a Genotype*
The arrangement of allele’s in the chromosome
What is the law of dominance
dominate genes are always expressed
F1 Generation
its homozygous- both the one allele, TT - tt
phenotype is 100%
genotype is 100%
What is the law of segregation
individual allele’s are segregated randomly
F2 Generation
Heterozygous - mix of allele’s
phenotype is 1:3
genotype is 1:2:1
what is the law of independant assortment
two individual traits segregate independantly of each other
Dihybrid Cross
phenotyp ratio is 9 : 3 : 3 : 1
9 homozygous
3 : 3 heterozygous
1 resessive
