Answer:
100% merle with long coats.
Explanation:
<em>All the offspring produced from the cross would be merle with long coats.</em>
<u>From the illustration:</u>
Merle gene is represented by the genotype cmcs.
fgf5 gene determines the coat phenotype. Let the gene be represented by the allele A. A determines long coat traits and it is dominant over its alternate form, b, which determines short coat trait.
Now, two merle (cmcs) dogs were mated. One is true-breeding for long coat (AA) while the other is true breeding for short coat (aa).
cmcsAA x cmcsaa
Progeny genotype = cmcsAa
cmcsAa = merle with long coat.
<em>Since </em><em>A</em><em> is dominant over </em><em>a,</em><em> all the progeny from the cross will be merle with long coat.</em>
(D), amount of time and area of physical contact between the substances

Dichotomous Key for Insects</h3><h3 />
This dichotomous key is a simplification and is used to find the order of most insects. But as in biology there is always someone or something to deny us, there are insects that defy this order 1.
Start by choosing between one of the two alternatives of option number 1 and go to the indicated number:
- - Obvious, membranous wings, sometimes covered with scales or fur: - Wings absent or forewings thick and hiding membranous hindwings: 15
- Wings covered with small scales and proboscis-shaped mouthparts: LEPIDOPTERA
- Wings not covered with scales, usually translucent. Mouthpiece is not a proboscis: 3
- - With a pair of wings: DIPTERA
- With two pairs of wings: 4
- - Long, narrow wings, fringed with fur. Size 5 mm or less: THYSANOPTERA
- Wings not narrow and fringed: 5
- - Abdomen with 2 or 3 long filaments. Small hindwings: EPHEMEROPTERA
- Abdomen with short filaments or none. Full-sized hindwings: 6
- - Forewings clearly longer and with a larger area than the hind wings: - Four forewings as long as, or nearly as long as the hind wings and with a similar or smaller area: 10
- - Wings hairy, opaque, with long palps antennae as long as the body or longer: TRICHOPTERA
- Transparent or translucent wings, hairless, palps short or absent, antennae shorter than the body: 8
- - Tarsus with 5 segments, usually with a wasp or bee face: HYMENOPTERA
- Tarsus with 2 or 3 segments, without a bee or wasp face: 9
- - Sucking mouthpiece, nozzle starting at the back of the head. Small to large: HOMOPTERA
- Chewing mouthpiece, without beak, length 7 mm or less: PSOCOPTERA
- - Head extended ventrally forming beak-shaped structure: MECOPTERA
- Head not extended ventrally: 11 - - Very short antennae with thick fur and large eyes: ODONATA
- Antennas not so short. Moderate to small eyes: 12
- - Hindwings wider than forewings. Cerci present: PLECOPTERA
- Hindwings as wide or almost as wide as forewings.
With this identification key we can taxonomically classify the 10 insects contained in the question, and with that we can discover the species we are studying.
Taxonomy is an important tool to better understand the species of living beings, their species diversity and their role in ecology.

The correct answer is taxonomy,
Taxonomy is a branch of biology that aims to to sort living thing into categories. In its early years, taxonomy was solely based on structural comparisons, mostly the anatomical similarities and differences between the organisms. However, with the discovery of the physiological processes and the genetic structures of organisms, the previous taxonomic knowledge was revised and changed in the light of the new scientific finds. Nowadays, taxonomy is primarily based on genetic similarities between the organisms.
