A idea that is repeatedly tested and widely excepted is
expeople1 [14]

Answer:

Theory

Explanation:

A scientific theory is what best fits your description. A scientific theory basically explains aspects of the natural world. However, scientific theories are not just ideas, it is based on collaborative works that tests the idea through the scientific method. Theories are verified through repeated testing.

Scientific hypotheses can eventually become a scientific theory when results have been verified through repeated testing.

In the fruit fly Drosophila, there is a dominant gene for normal wings and its recessive allele for vestigial wings. At another
aev [14]

Answer:

15

Explanation:

The genes for vestigial wings (vg) and purple eyes (pr) are linked on the same chromosome.

<u>The following cross was made:</u>

Heterozygous male for both genes   X female<em> vg pr / vg pr</em>  

The male could be either <em>vg+pr+/vg pr</em> or<em> vg+ pr/vg pr+</em>.

The female only produces <em>vg pr </em>gametes.

<u>The following offspring was observed: </u>

420 Normal wings and red eyes (<em>vg+ pr+/vg pr</em>)

430 Vestigial wings and purple eyes (<em>vg pr / vg pr</em>)

80 Vestigial wings and red eyes (<em>vg pr+ / vg pr</em>)

70 Normal wings and purple eyes (<em>vg+ pr / vg pr</em>)

Total: 1000

The individuals observed in the highest frequency have the parental genotypes. The recombinant individuals are <em>vg pr+ / vg pr</em> and <em>vg+ pr / vg pr.</em>

Distance = Number of recombinants × 100 / Total

Distance = (80 + 70)×100 /  1000

Distance = 15 cM.

<em>Just a small note, male drosophila do not experience crossing over in meiosis, so there would be no recombinants observed from this cross. The problem is probably mixed up, the female should be heterozygous and the male the homozygous recessive.</em>
