I believe the term for an observable trait of an organism would be called or noted as the organism's phenotype.

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 effect does sweating have on body temperature?

Dovator [93]

Answer: When the weather is hot or your body temperature rises due to exercise or fever, sweat is released through ducts in your skin. It moistens the surface of your body and cools you down as it evaporates.

Why is 2 the correct answer to number 16 ? Explain why please and answer this !!

marta [7]

an egg cell has a haploid nucleus so it has half the number of dna because it fuses with a sperm cell to have the full amount of dna.

an egg cell has 23 chromosomes and a sperm cell has 23 chromosomes.

they both have half the amount of dna to form a zygote

You are studying leaf development in a member of the mustard family. You identify several mutants of interest in this plant and

monitta

Answer:

•The relationship between the twist and the wild type flower in the first crossing is known as a COMPLETE DOMINANCE

•The relationship between the forked and the wild type flower in the second crossing is also known as a COMPLETE DOMINANCE

•The relationship between the pale and the wild type flower in the third crossing is known as an INCOMPLETE DOMINANCE

Explanation:

A complete dominance is characterised by having one of the genes (the dominant gene) in an heterozygous condition, completely masking the effect of the other (the recessive gene) of thesame allelic pair. E.g. if the genes in allelic is represented with Aa, "A" is said to completely dominate "a" if it does not allow "a" to Express itself phenotypically.

The heterozygous condition is always the result of the F1 generation

and the F2 generation of a Complete dominance is always characterised by a phenotypic ratio of 3:1 which is in line with the results gotten from the first crossing and the second crossing as stated in the question.

An complete dominance is characterised by having an intermediate progeny in the F1 generation which was evident in the result of the third crossing. Also a phenotypic ratio of 1:2:1 in the F2 generation is also a characteristic feature of an Incomplete dominance relationship which was also evident in the third crossing.
