In fruit gray body color is dominant over black body color suppose that a gray fruit fly heterozygous for the alleles for body color is crossed with one that has a black body what percentage of the?
In this case, when a gray fruit fly heterozygous for the alleles for body color is crossed with one that has a black body, all offspring will have a 50% chance of inheriting the gray body color and a 50% chance of inheriting the black body color. This is due to the fact that the gray body color allele is dominant and the black body color allele is recessive.
How do dominant and recessive alleles affect pheno type?
An allele can effect the phenotype of an organism by its dominance or recessiveness. If two dominant alleles are crossed the offsprings will carry the dominant trait of the alleles. If a dominant allele is crossed with recessive allele the phenotype of the offsprings will be of that of the dominant allele. And if two recessive alleles are crossed the phenotype of their offsprings will carry the reccesive trait.
Two plants are crossed resulting in offspring with a 3 to1 ratio for a particular trait This suggests?
The 3:1 ratio for a particular trait suggests that the trait is determined by a single gene with two alleles. It indicates that one parent is homozygous dominant for the trait, one parent is homozygous recessive, and the offspring are heterozygous.
If a female fruit fly heterozygous for red eyes crossed with a white eyed male what percent of their offspring would have white eyes?
All the offspring will have red eyes because the trait for red eyes is dominant and the female is heterozygous (carrying one dominant red eye allele). White eyes are recessive, so the offspring would need to inherit two white eye alleles to have white eyes.
How is a dominant trait represented in a punnett square?
Dominant alleles are written in upper case (i.e, 'A'), while recessive alleles are lower case (i.e, 'a')
In fruit gray body color is dominant over black body color suppose that a gray fruit fly heterozygous for the alleles for body color is crossed with one that has a black body what percentage of the?

In fruit flies, gray body color is dominant over black body color. Suppose two fruit flies heterozygous for the alleles that carry body color are crossed and 200 offspring are produced. How many would you expect to have black bodies?
50
Two plants are crossed resulting in offspring with a 3 to1 ratio for a particular trait This suggests?
The 3:1 ratio for a particular trait suggests that the trait is determined by a single gene with two alleles. It indicates that one parent is homozygous dominant for the trait, one parent is homozygous recessive, and the offspring are heterozygous.
If a female fruit fly heterozygous for red eyes crossed with a white eyed male what percent of their offspring would have white eyes?
All the offspring will have red eyes because the trait for red eyes is dominant and the female is heterozygous (carrying one dominant red eye allele). White eyes are recessive, so the offspring would need to inherit two white eye alleles to have white eyes.
What does a 1 to 1 phenotypic ratio in a test cross indicate?
A 1:1 phenotypic ratio in a test cross indicates that the organism being tested is heterozygous for a particular trait and is crossed with a homozygous recessive individual. This ratio suggests that the dominant and recessive traits are expressed equally among the offspring, with half exhibiting the dominant phenotype and half exhibiting the recessive phenotype. It confirms the presence of both alleles in the heterozygous parent.
How is a dominant trait represented in a punnett square?
Dominant alleles are written in upper case (i.e, 'A'), while recessive alleles are lower case (i.e, 'a')
A true breeding tall plant was crossed with a true breeding short plant If alleles did not segregate during gamete formation?
All offspring would be heterozygous for the gene controlling plant height. This is because if alleles do not segregate, they remain together and are passed on as a unit. The offspring plants would all be tall because the allele for tallness is dominant over the allele for shortness.
What offspring is produced if a heterozygous n tall pea plant is crossed with a homozygousfor this trait what percent of the offspring will be heterozygous?
If a heterozygous tall pea plant, Aa, is crossed with a homozygous plant, AA, for the trait, you will have a one in one in four chance of the offspring being heterozygous. You will need to create a square and plug the traits in to see what the odds are.
purple petal color in pea plants is dominant to white petal color two heterozygous pea plants are crossed what is the ratio of the offspring with white petals to the number total number of offspring?
3:1 ratio Two pea plants, both heterozygous for flower color, are crossed. The offspring will show the dominant purple coloration in a 3:1 ratio
A homozygous dominant brown mouse is crossed with a heterozygous brown mouse (White is the recessive color)?
A pretty bow
In a certain species plant the allele for tallness is dominant over the allele for shortness.to determine wether a tall plant is heterozygous should be crossed with a?
To determine whether a tall plant is heterozygous, it should be crossed with a homozygous recessive plant (short plant). If any offspring are short, the tall plant must be heterozygous; if all offspring are tall, the tall plant is likely homozygous dominant. This test cross allows for the observation of inheritance patterns in the offspring.
