1. four o'clock plants have a gene for colour and gene for height with the following phenotypes: rr: red flower, tt: tall flower, rr: pink flower, rr: white flower, tt: medium height flower, tt: dwarf flower. if a dihybrid plant is self-fertilised, give the portion of genotypes and phenotypes produced.

It is expected that 75% of the gametes produced by this plant have at least one dominant gene in their genotype and 25% are fully recessive.

  • RR: red flower
  • TT: tall flower
  • Rr: pink flower
  • rr: white flower
  • Tt: medium height flower
  • tt: dwarf flower.

What is Dihybrid in Genetics?

The concept of dihybrid is used in biology to name one or that which originates from the crossing of two organisms with different characteristics. This crossing gives rise to a diploid being that, in its nucleus, has two sets of homologous chromosomes.

With this information, we can conclude that It is expected that 75% of the gametes produced by this plant have at least one dominant gene in their genotype and 25% are fully recessive.
