Heredity
What is a trait?
An inherited characteristic
Where does protein synthesis START?
the nucleus
What type of cell replication creates body/somatic cells?
Mitosis
a pedigree
Who is credited for introducing the theory of Natural Selection?
Charles Darwin
When both alleles are present for eye color (coding for Brown and coding for blue Bb) The brown eyed allele is what the offspring has. Which allele is dominant in this gene?
Brown eyes
Why does DNA replication occur?
The cell is dividing
What does phase of mitosis does this picture show?
metaphase
What is the type of RNA that is used in protein synthesis
mRNA
What organism did Charles Darwin use to develop his ideas on artificial selection?
Pigeons
What two GENOTYPES would result from this cross BBxBb
BB & Bb
What are the nitrogenous base pairs that makeup DNA?
Adenine (A), Thymine (T), Cytosine (C), Guanine (G)
What are the results of mitosis?
two Identical daughter cells with the same number of chromosomes as the parent
If a cell has half the amount of chromosomes as a cell is it diploid or haploid
haploid
What is an adaptation?
a modification of an organism or its parts that makes it more fit for existence in a specific environment
What PHENOTYPES would result from this cross BB x Bb? If B=Brown eyes and b= blue eyes
All brown eyes
The following DNA strand is to be replicated, what is the correct mRNA strand that would be produced? ATT CGC TTA ACG
UAA GCG AAU UGC
What are the results of meiosis?
What is cytokinesis
when the cytoplasm splits
What is fitness?
An organism's ability to survive in an environment
How many genes do you get for each trait? Who do you get them from?
2 for each trait, you get them from your parents?
What is the cause that identical twins will not be the same at 50, even though they have the same DNA?
Environmental mutations
What is a disadvantage to sexual reproduction?
The amount of time and energy it takes to find a mate
What is an advantage of asexual reproduction
It's quick and you only need one parent
