In cattle black coat is dominant to white coat color a farmer has a black male of undetermined genotype how can the farmer determine the genotype of the male?
One way to determine the male's genotype would be to breed him to females with a known genotype of Black-Black. If any resultant calves were born with a white coat, you would then know that the male were Black-White. If calves were consistently black coated, you could be fairly certain he was also of the Black-Black genotype.

What is an observable trait of an organism that can mask a recessive trait?
The observable characteristic are called the genotype and any dominant trait can mask the recessive. An example would be Black Angus cattle can actually carry a red recessive trait because black is the dominant trait in cattle breeding
What is the difference between genotype and phenotype and give examples?
A genotype is the actual genetic coding for an organism A phenotype is the physical appearance For example, let's say BB or Bb is the coding for black hair. BB/Bb is the genotype, and the black hair is the phenotype
According to the rule of dominance if two different alleles are present is the dominant allele expressed?
the dominant allele is expressed when two (assuming you mean dominant and recessive) alleles are present. however, if the alleles are codominant they are both expressed.
Pattern of inheritance in which both alleles contribute to the phenotype of the organism?
The pattern of inheritance in which both alleles contribute to the phenotype of the organism is codominance. For example white and red hair color in cattle. Black and white feather color in certain chickens.
Why doesn't commensalism exist in nature?
Commensalism does exist in nature. It means a relationship between two organisms where one benefits and the other is not affected. An example is the cattle egret and cattle. The egrets live near the cattle and benefit by eating the insects stirred up by the cattle's hooves. The cattle are not affected.
What is an observable trait of an organism that can mask a recessive trait?
The observable characteristic are called the genotype and any dominant trait can mask the recessive. An example would be Black Angus cattle can actually carry a red recessive trait because black is the dominant trait in cattle breeding
What is example of a genotype?
There are genotypes and phenotypes discussed in genetics.Genotypes include both recessive and dominant genes, and is the genetic makeup of the organism.Phenotypes are only the traits that are observed in an organism, i.e. double-recessive, or dominant genes.If you looked at horned/polled(no horns) cattle. The polled gene is dominant, the horned gene is recessive.A cow with horns would be expressing the horned phenotype. It would also have the double-polled genotype since it is a recessive gene.A cow without horns would be expressing the polled phenotype. However, it could have either 2 polled genes for the genotype, or it could have 1 polled gene and 1 horned gene for the genotype.
What is the difference between genotype and phenotype and give examples?
A genotype is the actual genetic coding for an organism A phenotype is the physical appearance For example, let's say BB or Bb is the coding for black hair. BB/Bb is the genotype, and the black hair is the phenotype
Where are Ranching and cattle dominant in?
Ranching and cattle are dominant in regions with vast open spaces suitable for grazing, such as parts of the United States (like Texas and Wyoming), Canada, Australia, and parts of South America (such as Brazil and Argentina). These regions typically have a tradition of livestock production and ranching as an important part of the economy.
What is Colorado's dominant industry?
Colorado's dominant industries are agriculture including wheat, cattle, and sheep, tourism (especially skiers), mining (gold, silver), oil, finance, and manufacturing. Colorado has many ranches and ranchers as well.
Are senepol cattle horned or polled?
Polled. The dominant polled characteristics come from the Red Poll breed that is infused into this breed to make it the Senepol breed.
If a hornless bull mates with a horned cow what are the two genotypes of the two parents?
Hornless = polled. Polled cows and bulls can be either homozygous polled or heterozygous polled. So, since we have no idea of what kind of calf they produce, the genotypical cross will look like this: (H = polled and h= horned) H_ x hh "H_" symbolizes the unknown allele that the polled bull has. Is he hetero polled or homozygous polled? The "hh" of the cow symbolizes she is homozygous horned, since the horned trait in cattle is a recessive trait: polled gene is dominant.
If Mendel had performed experiments on cattle rather than on peas the patterns of inheritance would not have been easily detectable because cattle?
have a much longer generation time compared to peas, making it more difficult to observe multiple generations and patterns in a shorter period of time. Additionally, cattle may have more complex genetic interactions compared to peas, which could have made it harder to identify clear Mendelian inheritance patterns. Finally, the sheer size and complexity of the cattle genome could have made it challenging to pinpoint specific genetic factors influencing traits.
What was the cattle frontier?
The cattle frontier refers to the period in the late 19th century when cattle ranching became a dominant economic activity in the American West. This era was characterized by the extensive grazing of cattle on open ranges, driven by the demand for beef in eastern markets and the expansion of railroads. Cowboys played a crucial role in herding cattle and managing ranches, contributing to the romanticized image of the American West. However, this frontier eventually declined due to overgrazing, changing market conditions, and the enclosure of land.
According to the rule of dominance if two different alleles are present is the dominant allele expressed?
the dominant allele is expressed when two (assuming you mean dominant and recessive) alleles are present. however, if the alleles are codominant they are both expressed.
Cattle with both white hair and red hair are?
Mendel's principle of dominant and recessive alleles doe not explain why the heterozygous chickens have both red and white hair
What are body condition scores in cattle?
It is a means of measuring the amount of fat that cattle are carrying to determine health, fertility, and feed efficiency of that animal. BCS's are mainly performed in cows and heifers, but it's not uncommon to do a BCS on a bull either.
