5 Written questions

5 Matching questions

  1. Gametes
  2. Principle of dominance
  3. Polygenic traits
  4. Alleles
  5. How are different forms of a gene passed to offspring?
  1. a states that some alleles are dominant and others are recessive
  2. b one of a number of different forms of a gene
  3. c When gametes are made, the alleles for each trait seperate from each other. That way each gamete carries only one allele for each gene.
  4. d sex cells
  5. e trait controlled by two or more genes

5 Multiple choice questions

  1. states that genes for different traits can segregate independently during the formation of gametes
  2. 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
  3. 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.
  4. a fertilized egg
  5. During prophase, each copied chromosome matches up with its homologous chromosome. Crossing-over increases the allele combinations on chromatids. In metaphase, spindle fibers form. In anaphase, chromatids seperate. In telophase, a nuclear membrane forms around the chromosomes. During cytokinnesis, the cells spilt, and two cells are made.

5 True/False questions

  1. Define homologous chromosomesterm used to refer to chromosomes in which one set comes from the male parent and one set comes from the female parent


  2. If an offspring is homozygous recessive, what do you know about the parents?Mendel's principles of heredity form the basis of modern genetics.


  3. What symbol is used to represent a haploid?2N; N represents the single set of chromosomes found in a gamete.


  4. Fertilizationprocess in sexual reproduction in which male and female reproductive cells join to form a new cell


  5. Example of a phenotype in pea plants and list the genotype50% tall and short; TT, Tt, tt; Pea plant height may be either tall or short.
