What did Mendel do plants in order to perform cross-pollination
-he cut the male parts off one flower so it would reproduce with another female flower
How many alleles does an organism inherit from a single parent in a genre containing two alleles?
When and only when will a recessive trait show in a two allele gene?
-only when the diminant trait is not present
What does the genotype tt say about the parent?
- the child will not have the tall gene (recessive)
Why can certain traits disappear from one generation, but reappear in the best generation?
-because she trait might not be dominant but it’s still there
What is the probability of a coin flip?
What can the principles of probability be used for in genetics?
-to see the probability and the results of his genetic crosses
What is the difference between homozygous and heterozygous
- TT= homozygous (same alleles)
To which organism do Mendel’s pronciples of genetics apply?
What are the principles of dominance and segregation?
-dommance= some alleles are dominant\necessice
Segregation= formation of new genome, separation of genes
Give an example of codominance
-bird having both black and white feather inherited
Define incomplete dominar
-are allele is not completely dominant other another
Give an example of when genetics and the environment both influence changes in an organism?
-Shows joe hates changing color depending on its climate
What are some examples of polygenic traits
-skin color, eye color
