Basic body color for horses is influenced by several genes, one of which has several different alleles. Two of these alleles— th

Phantasy [73]

Answer:

<h2>No,</h2><h2>Phenotypic Ratio: 1 Chestnut : 2 Palomino : 1 Dilute</h2>

Explanation:

As given:

The chestnut (dark brown) allele and a diluting (pale cream) alleles show incomplete dominance, means that both the alleles in heterozygous condition show their effect. So the heterozygous show the phenotype which is intermediate of both the parents, here a horse heterozygous for these two alleles is a palomino.

There is in fact, no particular allele present for palomino, this phenotype only results due to having two different alleles for a gene. So, palominos can never be pure-breeding because they can never be homozygous.

Let P1 chestnut and P2 dilute,

Palomino is P1P2

The Punnett’s Square for palomino mated to palomino:

P1P2× P1P2

Gametes are: parent-1 P1 and P2 , parent-2: P 1 and P2

Progeny are: P1P1, P1P 2, P 2 P1, P2 P2

Genotypic Ratio: 1 P1P 1 : 2 P1P 2 : 1 P2P 2

Phenotypic Ratio: 1 Chestnut : 2 Palomino : 1 Dilute

The zebra mussel, a mollusk native to Eurasia, was first discovered in the Great Lakes of North America in 1988. Zebra mussels a

Anvisha [2.4K]

Answer:

Please see below

Explanation:

A. Zebra mussels are located in the areas of the United States that they were introduced to but it continues to spread across the US as time progresses.

B. Since the Zebra mussels can attach itself to solid surfaces, boats are no exceptions. They are able to go a few days out of water which gives them enough time to remain attached until a boater takes the vessel to another lake or isolated body of water.

C. Since these are filter feeders they are growing without a natural predator since they are an invasive specie. They feed on the algae in the water and use up almost all of this food supply and makes resources for other native specie (fish) that depend on this food source to die out.

D. Burmese pythons in the Florida everglades are an invasive specie. The prey on endangered species, have no real predator and have voracious feeding habits that affect the numbers in the animal population.

E. Non- native mongoose was introduced on Jamaica to control the snake population. The problem with introducing a non native specie would be that this new organism is also without a natural predator. After the target specie has been eliminated it may try to feed on other animals in the ecosystem as well.

F. Invasive species need to adapt to weather conditions and should be able to hunt/acquire its food in order to survive in its new environment.
