- What is the reason for codominance?
- What patterns of inheirtance are illustrated by ABO Human Blood Types? Explain.
- Prophase I
- How can we use probability to predict traits?
- a separation of alleles
- b One pattern of inheirtance is codominance and the examples are A is equally dominant to B, so the blood type is AB. Multiple alleles have three possible alleles which are A,B,and O
- c Punnett squares use probability to predict the combinations of alleles in a genetic cross.
- d The phenotypes for both alleles are equally expressed in the offspring.
- e Each chromosome pairs with its corresponding homologous chromosome to form a tetrad.
5 Multiple choice questions
- process by which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell
- In four o'clock plants the R stands for red and W stands for white flowers. If a plant is RR, then the flower will be red. If WW, then the flower will be white.
- The offspring recieved one recessive allele from each parent.
- trait controlled by two or more genes
- TtYy; First: TY; Outside: Ty; Inside: tY; Last: Ty. The F.O.I.L. method determines all the possible allele combinations
5 True/False questions
Gametes → sex cells
Define true-breeding → A hybrid is the offspring that crosses between parents with different traits.
Anaphase II → The fibers pull the homologous chromosomes toward opposite ends of the cell
What happens during each phase of Meiosis I? → During prophase, the chromosomes become visible. During metaphase, the chromosomes line up in the middle of the cell. During anaphase, the chromatids seperate. During telophase and cytokinesis, four new haploid cells are formed.
What is meant by a polygenic trait? → trait controlled by two or more genes
