What did Mendel do most of his work with?
Garden peas
What is the P generation?
the parent generation
What is the f2 generation?
the offspring of the f1 generation
What are biotic and abiotic things, give an example of each
answers vary

25%
Where did Mendel do most of his work?
in the monastery garden
What is the F1 generation
the offspring of the P generation
What does homozygous and heterozygous mean, give an example of each.
same alleles and different alleles, AA and Aa
What is an autotroph
something that makes its own food using the sun, plants
In rabbits, brown fur is dominant to white fur. 2 Heterozygous brown rabbits have been crossed. What percent of their offspring would also be brown?
75%
What law states that some alleles are dominant and some are recessive?
the law of dominance
What does genotype and phenotype mean? give an example of each
genotype= the genetic makeup (AA)
phenotype +the expressed traits that you can see (brown hair)
The gamete contributed by the mother
the egg
what is the lowest level of ecological organization that includes non-living things
ecosystem
if the P1 generation is a cross between 2 homozygous recessive parents, what percent of the F2 generation would be showing the dominate trait?
0%
what law states that genes for different traits are inherited independently from each other?
the law of independent assortment
when sperm and egg combine, they make this
zygote
different forms of a gene
allele

What is a monohybrid cross, and what is a dihybrid cross?
monohybrid cross is crossing only one trait, and a dihybrid cross is two traits, containing 16 boxes in the punnett square
which law states that when the gametes are produced the gene pairs separate and each gamete receives one allele
the Law of Segregation
the exchange of genetic material between non-sister chromatids during meiosis
crossing over
cells containing 2 alleles for each trait are called what?
diploid
