Reproduction
How are gametes formed by meiosis?
What is Cell division, crossing over, and splitting of homologues.
3 major phases of vertebrate development
what is cleavage, gastrulation, and cell differentiation?
monohybrid cross, its expected phenotype and genotype ratio in the f2 generation, and the law of heredity
what is a cross between to hybrid parents, 3:1 and 1:2:1, and the law of genes needing to be passed down through generation?
epigenetics
what is the study of modifications in gene expression
diversity of type and unity of pattern
what is the concept of how diverse our environment is and similarities between all species?
Compare asexual and sexual reproduction
What is Asexual reproduction produces an identical offspring of the single parent and sexual reproduction produces genetically varying offspring of two parents?
How do cells differentiate even though their DNA is identical?
what is cell differentiation and turning certain genes on or off?
deviations from the law of heredity observed by mendel
what is incomplete dominance, mutations, multi allele traits
how can epigenetic modification change gene expression
what is environmental impacts change how genes are expressed and coded
evidence supporting evolution
what is fossil records, homologous structures, vestigial structures, embryology, biochemistry, geographic distribution, and behavio?
How is genetic variation introduced in sexual reproduction
what is crossing over and interchanging of traits?
compare reproduction and development in the 5 vertebrate groups
amphibians: external fertilization and lay eggs. mammal: internal fertilization and give birth. reptiles: in fertilization and lay eggs. aves: internal fertilization and lay eggs. fish:external fertilization and lay eggs
DNA structure
what is a double helix ladder like structure with sugar and phosphate backbones and “rungs” of nitrogen bases
mutations and point v chromosome
what is mistakes in the genetic code and change in one or a few gene tags v the addition or removal of a whole chromosome
artificial selection v natural selection
what is man made forced breeding choice v naturally occurring
compare the human female and male reproductive systems
what is men produce sperm in the testes and women produce eggs in the ovaries
How is placental mammalian development different
how do genes code for protein production
what is 98% controls the 2% that control protein production?
biotechnology
what is the human manipulation of living things to create product?
punctuated equilibrium v. gradualism
caused by a extreme event and causes species to quickly branch off v natural change overtime and species branch off gradually and slowly
phases of meiosis
what is interphase, prophase i, metaphase i, anaphase i, telophase i, prophase ii, metaphase ii, anaphase ii, telophase ii?
stem cells
what are unspecialized cells?
Why are proteins so important?
what is they build structure, create transport passageways, create enzymes, create antibodies, and create hormones
bioethical questions regarding biotech
what is what are the effects on the animal and the environment? what are the ethics behind genetic modification?
evolutionary patterns
what is
adaptive radiation: species branch off from common ancestor. convergent: species don’t share a common ancestor but share traits due to their environment parallel: species share a common ancestor and share many traits coevolution: species do not share a common ancestor but evolve alongside each other
