Color in poison dart frogs is controlled by a single gene with multiple alleles. A blue poison dart frog that is heterozygous fo

r the blue allele (Cb) and red allele (Cr) is crossed to a yellow poison dart frog that is heterozygous for the orange (Co) and yellow (Cy) alleles. Their progeny are 1/2 blue, 1/4 orange, and 1/4 yellow. Determine the order of dominance for the alleles. (Order of dominance is indicated as: A > B > C > D such that A is dominant over all alleles, B is dominant over C and D, C is dominant only to D, and D is recessive to all alleles.)

Answer:

Cb>Cy>Co>Cr

Explanation:

First of al we need to do the Punnett square. As a result we get the genotypes:

CyCb

CyCr

CoCb

CoCr

Because there are no red frogs, red is the least dominant as it isn't expressed in any genotype.

Half of the progeny are blue and half of the possible genotypes contain the blue allele meaning that blue is expressed in all genotypes. This means that blue is the most dominant.

The only alleles left are yellow and orange. We can deduce that yellow is more dominant than orange because one of the parent frogs is yellow and contains the genes for yellow and orange.

As a result blue is the most dominant, yellow is the second most dominant, orange is the third most dominant and red is the least dominant.

Discuss ecological pyramids, use tropic levels to discuss this process of heat loss.
Dima020 [189]

Answer:

Energy pyramids is representation of food chain where producers lie at the base of pyramid followed by primary, secondary and tertiary consumer. A tertiary consumer lies at the top of the energy pyramid .

Explanation:

An ecological pyramid is a chronological arrangement of organism in which the organism producing the food lies at the base of pyramid and remaining all organism lie above it.

Each level of an ecological pyramid is called a trophic level and an organism lying at any trophic level feed upon organism lying in trophic level prior to it.

Energy transferred to an organism lying at certain trophic level is 10% of the energy contained in an organism lying at its lower trophic level. remaining 90% of the energy is used by an organism for its internal metabolic process.

LenKa [72]

Answer:

The best way to classify two different organisms that have similar appearance and are found in the same environment is to use gel-electrophoresis to compare DNA patterns.

Explanation:

When organism possesses the same physical characteristics and are found in the same environment the genetic test must be varried out to ascertain their differences such as DNA test using electrophoresis to compare such
