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?

If the heterozygous cross prodeces 736 offspring how many will be wondercorn?

To determine the number of wondercorn offspring from a heterozygous cross, we need to know the inheritance pattern and the ratio of offspring phenotypes. Assuming wondercorn is a dominant trait and the cross is between two heterozygous individuals (e.g., Aa x Aa), the expected phenotypic ratio would be 3:1 (dominant to recessive). Therefore, out of 736 offspring, approximately 552 would be wondercorn (3/4 of 736).

How many different genotype variations are possible in the offspring of these crossed rose bushes?

To determine the number of different genotype variations possible in the offspring of crossed rose bushes, you need to know the specific genotypes of the parent plants and the inheritance patterns (e.g., dominant/recessive traits). If both parent plants are heterozygous for a trait (e.g., Aa x Aa), then using a Punnett square would show that there are four possible genotypes (AA, Aa, Aa, aa). The total variations can vary widely based on the number of traits being considered and their allelic combinations. Without specific genotypes or traits, an exact number cannot be provided.

How many kinds of genotype will the offspring have?

it always depends....

How can you determine that genotype of a plant that displays the dominant form of a trait?

Do a testcross with a homozygous recessive plant.

When should you use punnett squares?

Punnett Squares are used to depict crosses of the parental or P generation and the possible offspring or F1 generation which can be formed from the traits being looked at which are represented by letters such as W for widow's peak, w for none, Y for yellow, y for green, so on and so forth. The diagrams depict the possibility of each offspring inheriting a specific/specific traits. Depending on the number of characteristics being looked at, the punnett square will range in size; the simplest is a 2x2 which states the possibility of offspring have 2 traits (2 traits of parents are being looked at; that is, whether or not parents have a characteristic/feature in relation to the possibility that their offspring will or will not). Ultimately, the outcomes depend on whether or not a trait is dominant, heterozygous, or recessive Dominant traits, represented by uppercase letters, generally overpowers the recessive traits which are represented by lowercase letters. Moreover, phenotypic and genotypic ratios can be found through Punnett Square crosses. Phenotypic ratios refer to the number of offspring with each specific physical characteristic/trait coded for by the different letter combinations and the genotypic ratios refer to the number of offspring with each different code. These ratios are separated by numbers and colons and begin at the top left corner of the square. Make sure to simplify if needed. For example: A homozygous dominant plant (RR) is crossed with a heterozygous round plant (Rr) --> RR x Rr RR x Rr: RR RR Rr Rr Phenotypic Ratio: 1 Round (100% chance of offspring being round) Genotypic Ratio: 1 RR: 1 Rr (50% chance of offspring being RR/Rr)

Dimples are a dominant characteristic If one parent does not have dimples and one parent is heterozygous for dimples what chance does a child have for getting dimples?

The child has a 50% chance of inheriting dimples. This is because dimples are a dominant trait, so if one parent is heterozygous for dimples, they will have one dominant allele for dimples to pass on to their child. The child would need to inherit this dominant allele from the heterozygous parent in order to express the trait.

How the number of the observed offspring in a genetic cross can be determined?

The number of observed offspring in a genetic cross can be determined by conducting controlled breeding experiments, where specific parental genotypes are crossed. The resulting offspring are then counted and recorded, typically using a Punnett square to predict expected ratios based on Mendelian inheritance. By comparing the actual number of offspring to the expected ratios, researchers can analyze inheritance patterns and gene interactions. This process helps in understanding the genetic makeup and traits of the offspring.

What is the phenotypic ratio of a monohybrid cross?

In a monohybrid cross with one parent homozygous dominant and the other homozygous recessive The phenotype of the F1 offspring will be 100% that of the parent with the dominant allele. A cross of two of the F1 offspring will be 75% phenotypically like the dominant allele and 25% will be hommozygous recessive or 3 to 1

What number is dominant?

== ==

How do you find recombination frequencies on a chromosome?

Recombination frequency = (Recombinant offspring) / (Total offspring) i.e. the recombination frequency is calculated by taking the number of recombinant offspring and dividing it by the total number of offspring.

What does the number 32 stand for in Biblical numeric's?

Offspring

If 675 plants resulting from the cross display a trait controlled by a dominant allele how many plants will show the trait controlled by the recessive allele?

In a gene loci there can be four combinations of 2 alleles. Suppose these possible allele combinations are called D for dominant and R for Recessive. The possible combinations for two of them are DD, DR, RD and RR. Wherever the D occurs the dominant trait will be displayed. There is only 1 where the recessive trait is displayed and this is the last or RR case. There must be 3 times the number of cases of the dominant trait as the recessive so the recessive trait is displayed in 675 / 3 cases or 225
