- If an offspring is homozygous recessive, what do you know about the parents?
- Multiple alleles
- Telophase II and Cytokinesis
- How is meiosis different from mitosis?
- Name the pattern of inheritance that would produce the speckled chicken with black and white feathers
- a Codominance
- b a gene that has more than two alleles
- c meiosis II results in 4 haploid daughter cells
- d The offspring recieved one recessive allele from each parent.
- e Mitosis can be a form of asexual reproduction, does not change the number of chromosomes, and makes two identical diploid cells. Meiosis is a step in sexual reproduction, cuts chromosomes in half, and makes four different haploid cells.
5 Multiple Choice Questions
- A hybrid is the offspring that crosses between parents with different traits.
- one allele is not completely dominant over the other allele
- 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.
- Mendel's principles of heredity form the basis of modern genetics.
- process in which homologous chromosomes exchange portions of their chromatids during meiosis
5 True/False Questions
Haploid → term used to refer to a cell that contains only a single set of genes
Explain how to determine the gametes for a dihybrid cross when the parent gamete is TtYy → TtYy; First: TY; Outside: Ty; Inside: tY; Last: Ty. The F.O.I.L. method determines all the possible allele combinations
Does the environment have a role on how genes determine traits? → Punnett squares use probability to predict the combinations of alleles in a genetic cross.
Example of a polygenic trait in humans. → Skin color
Metaphase II → the chromosomes line up in a similar way to the metaphase stage of mitosis
