- Metaphase I
- Multiple alleles
- Example of a phenotype in pea plants and list the genotype
- a 50% tall and short; TT, Tt, tt; Pea plant height may be either tall or short.
- b The principle of independent assortment states that genes for different traits can segregate independently during the formation of gametes
- c meiosis I results in two haploid daugther cells, each with half the number of chromosomes as the original cell
- d a gene that has more than two alleles
- e Spindle fibers attach to the chromosomes
5 Multiple choice questions
- The diploid cells of most adult organisms contain two complete sets of inherited chromosomes and so two complete sets of genes.
- Situation in which the phenotypes produced by both alleles are completely expressed
- separation of alleles
- 2N; N represents the single set of chromosomes found in a gamete.
- having two identical alleles for a trait
5 True/False questions
If an offspring is homozygous recessive, what do you know about the parents? → The offspring recieved one recessive allele from each parent.
What is the reason for codominance? → The phenotypes for both alleles are equally expressed in the offspring.
Define homologous chromosomes → Chromosome pairs of the same length, centromere positions, and staining patterns for the same characteristics.
Where does an oganism get its unique characteristics? → An individual's unique characteristics are determined by factors that are passed from parent to offspring.
Define hybrid → A hybrid is the offspring that crosses between parents with different traits.
