This question relates to the inheritance of two linked genes, the ‘E gene’ and the ‘B gene’. Each gene has a dominant allele, shown with the upper-case letter (E and B, respectively) and a recessive allele, shown with the lower-case letter (e and b, respectively). Two pure line parents were crossed together to produce a dihybrid F1 individual. This F1 individual is crossed with a tester parent. The F2 test cross progeny are stated below. Use this information to answer the following questions. F2 Test cross progeny Genotype       Number eB/eb              75 Eb/eb              76 EB/eb             25 eb/eb              24 Which one of the following options most accurately states the genotype of the dihybrid F1 individual in this scenario? eB/eB Eb/eb EB/eb eB/Eb

Question

This question relates to the inheritance of two linked genes, the ‘E gene’ and the ‘B gene’. Each gene has a dominant allele, shown with the upper-case letter (E and B, respectively) and a recessive allele, shown with the lower-case letter (e and b, respectively).

Two pure line parents were crossed together to produce a dihybrid F1 individual. This F1 individual is crossed with a tester parent. The F2 test cross progeny are stated below. Use this information to answer the following questions.

F2 Test cross progeny

Genotype       Number

eB/eb              75

Eb/eb              76

EB/eb             25

eb/eb              24

Which one of the following options most accurately states the genotype of the dihybrid F1 individual in this scenario?

  1. eB/eB
  2. Eb/eb
  3. EB/eb
  4. eB/Eb
