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

Question: A rat approaches a piece of rotting fruit, takes a small bite, and runs away. Which statement best explains the reason
Anna [14]

Answer: See below

Explanation:

There should be another answer that can be chosen: the rat’s chemical receptors detect chemicals in the fruit that alert the rat to possible danger. Sensory receptors in the rat's whiskers respond to input about the texture of the fruit, maybe it's slimy or rancid, if if it was another factor such as the environment, it wouldn't have approached the fruit in the first place.
