Based on the hypothesis that the two genes for eye color and body color obey Mendel's law of independent assortment, calculate the expected values of each of the four phenotypes. (Use the actual and expected data shown to the left)total is 2,205 of F2 generation.expected Mendelian ratios= 1:1:1:1
  • There would be twice as many in each nonrecombinant class grouping.
  • The expected number of offspring with each phenotype is 551.
  • The two genes for eye color and body color obey Mendel's law of independent assortment.
  • rejected
-two pairs of sister chromatids
  • syntenic
  • bivalent
  • True
  • haploid
-frequency of recombinant offspring due to crossing over provides a way to deduce the linear order of genes along a chromosome
  • genetic linkage
  • genetic linkage or simply linkage
  • genetic recombination
  • genetic linkage map
.Based on a X2 value of 2110, the hypothesis that the two genes for eye color and body color obey Mendel's law of independent assortment, should be:
  • genetic map
  • rejected
  • haploid
  • genetic linkage
-genes that are close together on the same chromosome tend to be transmitted as a unit
  • genetic map
  • genetic linkage
  • genetic linkage map
  • genetic linkage or simply linkage
-two or more genes are located on the same chromosome-physically linked to each other, because each eukaryotic chromosome contains a single, continuous, linear molecule of DNA

A diagram that depicts the sequence of genes along a chromosome is called a ________________ ________
  • genetic map
  • genetic linkage or simply linkage
