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

What is responsible for the yellow-orange coloration of leaves in the fall?

mixer [17]

The correct answer is - C) carotenoids.

The majority of the trees from the mid-latitude forests tend to shade their leaves in the autumn. This process occurs because of the seasonal changes in the climate, where the trees tend to be almost not-active during the winter, so in order to preserve as much energy and nutrients as possible they get read off their leaves.

It is not a sudden process, but it takes some time, where the leaves from the initial green color start to change to yellowish, than towards orange, reddish, or brownish before they fall.

The reason why this coloration appears in the leaves when the tree starts to process of shading them off are carotenoids. The carotenoids found in the leaves, the lutein and the beta-caroten, thorugh the xantophills and the flavonoids give a yellowish color to the leaves, thus we get the beautiful autumn colors and landscapes.
