What else can I help you with?
What are the genotypes of the parental dogs one is black the other is brown who have ONLY black or yellow puppies. Explain how you determined their genotypes.?
BBEe and bbEe. Black is dominant, and brown is recessive. Yellow is also recessive. Because one parent is brown, for none of the puppies to also be brown the black parent cannot carry the recessive allele on the B locus. Because neither parent is yellow but some of the puppies are, both parents must carry the recessive allele on the E locus.
If a child has blond hair and both of her parents have brown hair what does that tell you about the allele for blond hair?
Both of the parents were heterozygous with the blonde hair allele, which is recessive. When there are two parents that are heterozygous, there is a 25% chance their offspring will get two of the recessive alleles. A punnett square can be useful when determining the different phenotypes and genotypes possible in offspring
What is meant by observed genotypes?
A phenotype is a physical characteristic. For a human an observed phenotype example would be hair colour (e.g brown) or eye colour (green). An observed phenotype is a physical characteristic that can be seen directly or indirectly (internal organs) caused by an individual's genotype.
How many puppies can a girl black lab and a brown boy have?
up to 10 puppies
How do you determine how many offspring will be the dominant color?
You can use a Punnet Square to figure it out. For example, if gray elephants dominate over brown elephants, and you cross 1 homozygous gray elephant (GG) and one homozygous brown elephant (gg), the Punnet square predicts that the offspring will all be heterozygous Gg. They will all be gray, however, because gray dominates over brown.
If a black and brown rabbit mate out of 4 offspring how may would be dark brown?
If a black and brown rabbit mate, their offspring could potentially have a mix of black, brown, and dark brown fur. It is not possible to predict exactly how many offspring would be dark brown without knowing the genetics of the parents. Each offspring has a different combination of genes that determine its fur color.
What would be the observable color of the offspring if both chromosomes coming from the parents has brown hair color?
his offspring hair color will be brown
What is the main color of a dog?
The most probable color is brown.
Can a lab have yellow and black and brown puppies or can they only have a certain color depending on the puppies parents?
Any color.
How A Bb guinea pig crosses with a Bb guinea pig all four off springs re black how does this happen?
In guinea pigs, the black coat color is typically determined by the dominant allele (B), while the brown coat color is determined by the recessive allele (b). When two Bb guinea pigs are crossed, the possible genotypes of the offspring are BB, Bb, Bb, and bb, resulting in a 3:1 phenotypic ratio. However, if all four offspring are black, it suggests that the bb genotype did not occur, possibly due to a selection bias in the observed offspring or an error in the initial assumption about the parents' genotypes.
What is the offspring brown bird pelican?
three
What is a Punnett square?
A Punnett square is a four-square diagram for showing the probabilities of an offspring to inherit a certain pair of alleles from its parents.For example,___T_ t__T | TT| Tt |t | Tt | tt |The Tt's (representing both parents' genotype) outside the Punnett square tell what the inner four squares will read. The inner squares tell what trait the parents' offspring might have.The Punnett square above shows that the offspring has a 25% chance of inheriting the homozygous dominant trait, 50% chance for heterozygous trait, and 25% for recessive.A Punnett Square takes two genotypes (discriptions of a gene) and determines the likelihood of four possible offspring carrying the genotypes. For example, blue eyes is a recessive gene. In order to have blue eyes, someone must have the genotype bb. The genotype BB or Bb would appear as brown eyes, the dominant trait. A Punnett Square of a blue-eyed organism and a brown-eyed organism (who carries the trait for blue eyes) would result in four potential offspring with the genotypes Bb, Bb, bb, and bb (two offspring have blue eyes and two have brown eyes but carry the blue-eyed trait). Punnett Squares allow scientists to predict POSSIBLE outcomes; they don't necessarily determine the offsprings' genotypes.
