Gregor Johann Mendel

Definition

Shows parents pass heritable

factors (genes) to offspring through peas

Term
What is the equivalent to sperm and eggs in a flower
Definition
sperm = stamens
eggs = carpel
Term
What is a monohybrid cross
Definition
inheritance of a single characteristics
Term
What is a homozygous genotype
Definition
has identical alleles
Term
what is a heterozygous genotype
Definition
two different alleles
Term
Give an example of a dihybrid cross
Definition
ie: round yellow seeds x
wrinkled green seeds observe there are two alleles tracked
Term
Mendels laws reflect what two rules of probability
Definition
rule of multiplication
rule of addition
Term
what is a pedigree
Definition
can be used to track genetic traits
Term
What are some ways you can
obtain a genetic test for a unborn child
Definition
Amniocentesis - obtain amniotic fluid
via needle inserted through abdomen
Chorionic villus sampling - suctioning
out fetal cells
Term
What is incomplete dominance
Definition
Neither allele is dominant over the other
Term
Describe the blood types
Definition
AB - universal acceptor - donates to AB
A - Accept all but B, donate to A+AB
B - Accept all but A, donate to B+AB
O - universal donor, accept only o.
Term
What is polygenic inheritance
Definition
Many genes influence one trait
ie: skin color affected by at least 3 genes
Term
How can you create new combination of alleles
Definition
crossing over
Term
define locus
Definition
a specific site of a particular gene
on its chromosome
Term
