NeTakaya

Answer:

Providing a controlled source of water vapour through which water can be vaporized into the plant envoirment.

Explanation:

Humidity ratio is the ratio of the mass of water in air to the mass of dry air. Humidity is needed in some conditions where the air is very dry. In a very dry air setting, there can be excess moisture loss from the plant surface, increasing the Humidity ratio can counter this effects and reduce excess moisture loss.

Imagine you do a test cross between a purple-flowered pea plant having serrated leaves (a dominant trait) and a white-flowered p
Rom4ik [11]

Answer:

genes for flower color and edge shape are linked. They do not assort independently.

Explanation:

<u>Available data:</u>

  • test cross between a purple-flowered pea plant having serrated leaves and a white-flowered pea plant having smooth edges.
  • serrated leaves → dominant trait
  • smooth edges → recessive trait
  • purple color → dominant trait
  • white color → recessive trait
  • F1: 4 purple-serrated:1 purple-smooth:1 white-serrated:4 white-smooth.

There are two genes involved in the cross. The expected ratios are 1:1:1:1 because we assume genes assort independently. However, we see a different phenotypic distribution. When phenotypic ratios differ from the expected ones, it means that genes are linked.

To know if two genes are linked in the same chromosome, we must observe the progeny distribution. If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. But if instead of this distribution, we observe a different one, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent
