- If 2 heterozygous organisms are crossed what percent of their offspring will also be heterozygous?
- How many haploid and diploid cells are produced from meiosis?
- Assuming a 3:1 ratio in the F2 generation, if you counted 1500 dominant purple flowers, about how many recessive white flowers would you expect?
- If two heterozygous (Hh x Hh) organisms are crossed, what will be the genotypes and percentages of their offspring?
- Polygenic traits such as skin color will produce a bell shaped curve graph, showing most individuals falling in the middle range. Which other polygenic traits from your notes would you expect to produce a similar bell-shaped curve?
- What is another name for a heterozygous organism?
- Draw a Punnett square for a cross between Tt x tt, and list the genotypes and phenotypes of the possible offspring.
- In a dihybrid cross of homozygous dominant & homozygous recessive parent (RrYy x RrYy), what fraction of the offspring will be recessive for both trait?
- What is the chance an individual will get Huntington's disease if one of their parents has it?
- What are alleles? Assuming Mendelian Genetics, how many alleles do you get from each parent from a particular trait.
- In a habitat that changes frequently, how is sexual reproduction an advantage over asexual reproduction?
- What process reduces the umber of chromosomes in half?
- If 2 genes are close together on a chromosome, are they more of less likely to separate during crossing over?
- If a homozygous dominant parent is crossed with a homozygous recessive parent all the offspring in the generation will be __________?
- What process returns the haploid gamete cells to diploid?
- Do men and women have different numbers of chromosomes in the gamete cells?
- Chloroplasts absorbs energy from sunlight and water molecules are broken down
- 1. Carbon dioxide molecules into the Calvin cycle.2. Energy added to molecules in the cycle; molecules rearranged into higher energy molecule.3. High energy, three carbon molecule leave the cycle; two are bonded together to make a six carbon sugar.4. Energy added to molecules remaining in the cycle to change them into five carbon molecules.
- 1. Energy absorbed from sunlight, and transferred to electrons that an electron transport chain (ETC)2. Water molecules are broken down; electrons enter chlorophyll.3. Energy from electrons in transport chain is used to pump H+ ions across the thylakoid membrane.4. Energy, absorbed from sunlight is transferred to electrons.5. High energy electrons used to produce an energy carrying molecule called NADPH.6. H+ ions flow (by diffusion) through a channel in the thylakoid membrane7. The channel is part of ATP synthesis, which produces ATP
- Produce their own energy: produce chemical energy for themselves and other organism
