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:

Explanation:

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

The following cross was made:

Heterozygous male for both genes X female vg pr / vg pr

The male could be either vg+pr+/vg pr or vg+ pr/vg pr+.

The female only produces vg pr gametes.

The following offspring was observed:

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

430 Vestigial wings and purple eyes (vg pr / vg pr)

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

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

Total: 1000

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

Distance = Number of recombinants × 100 / Total

Distance = (80 + 70)×100 / 1000

Distance = 15 cM.

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.

A particular plant species is pollinated by a certain insect species the insect species depends on the plant species with food w

Travka [436]

The correct answer is co-adaptation.

Co-adaptation in biology refers to the procedure by which two or more species, phenotypic traits or genes go through adaptation as a group or pair. This takes place when two or more associating features go through natural selection together in response to the similar selective pressure or when selective pressures change one feature and simultaneously changes the interactive feature. These associating features are only beneficial when together, in certain cases resulting in increased interdependence.
