What is a breeding experiment where a single trait controlled by two alleles is examined called?
monohybrid cross
What describes the mating of organisms that have different homozygous alleles for a single trait?
The mating of organisms with different homozygous alleles for a single trait is referred to as a monohybrid cross. In this scenario, one parent possesses two dominant alleles (homozygous dominant), while the other has two recessive alleles (homozygous recessive). The offspring produced from this cross will be heterozygous, displaying the dominant trait, while the recessive trait will not be expressed in the phenotype. This type of cross is often used to illustrate basic principles of Mendelian inheritance.
How would a recessive trait show up in a cross between two individuals with a dominant phenotype?
In a cross between two individuals with a dominant phenotype but carrying a recessive trait, the recessive trait would not be visibly expressed in the offspring (since they don't inherit two copies of the recessive allele). However, they would be carriers of the recessive trait, meaning they could pass it on to future generations.
This cross is used when studying one trait?
The cross used when studying one trait is known as a monohybrid cross. This type of genetic cross examines the inheritance of a single characteristic, typically involving two parents that differ in that trait. By analyzing the offspring, researchers can determine the dominance relationships between alleles and predict the genotypic and phenotypic ratios in the next generation. Gregor Mendel famously used monohybrid crosses in his experiments with pea plants to establish foundational principles of heredity.
How many boxes does a Dihybrid cross have?
A dihybrid cross results in 16 boxes for the offspring. For example, the cross RrDd X RrDd is shown below:RDRdrDrdRDRRDDRRDdRrDDRrDdRdRRDdRRddRrDdRrddrDRrDDRrDdrrDDrrDdrdRrDdRrddrrDdrrdd
What is a cross between parents that differs in one trait called?
It is a dihybrid cross.An example: if you cross garden peas having round yellow seeds with others having wrinkled green seeds, that is a dihybrid cross, because you are tracking both seed shape and seed color.
What is a breeding experiment where a single trait controlled by two alleles is examined called?
monohybrid cross
What is the difference between a monohybrid and dihybird cross?
A monohybrid cross involves the study of one trait or gene, whereas a dihybrid cross involves the study of two traits or genes simultaneously. In a monohybrid cross, only one pair of alleles is considered, while in a dihybrid cross, two pairs of alleles are considered.
How does a monohybrid differ from a dihybrid with respect to allele pairs?
monohybrid is a cross between two heterozygous (Aa x Aa), they are usually controlled by different alleles of the same gene. A monohybrid cross compares only one trait. while Dihybrid is a cross between F1 offsprings of two individuals that differ in two traits. Dihybrid croos are often used to test for dominant and recessive genes in two separate characteristics.

What is a reciprocal cross in genetics?
A reciprocal cross in genetics involves two organisms that differ in a specific trait, where each organism is used as a parent in separate crosses. For example, if one plant with trait A is crossed with a plant with trait B, the reciprocal cross would involve the plant with trait B being crossed with the plant with trait A. This approach helps determine if the traits are influenced by sex or if they are inherited independently of parental sex. It is commonly used in studies of inheritance patterns and gene interactions.
How would a recessive trait show up in a cross between two individuals with a dominant phenotype?
In a cross between two individuals with a dominant phenotype but carrying a recessive trait, the recessive trait would not be visibly expressed in the offspring (since they don't inherit two copies of the recessive allele). However, they would be carriers of the recessive trait, meaning they could pass it on to future generations.
What is a momohybrid cross?
Mono means "one" and the two parent plants differ from one another by single trait-height.
What is momohybrid cross?
Mono means "one" and the two parent plants differ from one another by single trait-height.
How many traits are examined in a monohybrid cross?
A monohybrid cross examines the inheritance of one specific trait, typically focusing on a single gene with two different alleles. This allows for the study of how these alleles are passed from parent to offspring.
A cross that considers one pair of contrasting traits?
A monohybrid cross considers one pair of contrasting traits (or alleles) in an offspring resulting from the mating of individuals that differ in only one trait. This type of genetic cross allows predictions about the inheritance pattern of a specific trait based on the known genotypes of the parents.
Albinism or the lack of color is a recessive trait that is present in some plants Cross two carriers for albinism If 500 plants resulted from the cross what percent of offspring would be expected?
25%
