What proportion of the offspring from this cross will have smooth yellow peas?
Since smooth yellow peas are dominant traits (represented by genotypes RRYY or RRYy), all offspring from a cross between two plants with smooth yellow peas will also have smooth yellow peas. Therefore, 100% of the offspring will have this phenotype.
If R is dominant to r the offspring of the cross of RR with rr will be homozygous?
R R r Rr Rr r Rr Rr That is the Punnet Square. The genotype will be 100% Rr in the cross. The phenotype will be whatever phenotype is constituted by your dominant allele.
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 the name of the offspring of a first cross?
The offspring of a first cross between two different breeds or species is known as a hybrid.
Which genotype is used in a test cross?
In a test cross, one individual with a dominant phenotype but unknown genotype is crossed with a homozygous recessive individual. The genotype of the individual with the dominant phenotype can then be inferred based on the phenotypic ratios of the offspring.
What is the phenotype ratio of a cross between a heterozygous male and female?
The phenotype ratio will depend on the specific genetic traits being studied. In general, a cross between two heterozygous individuals is expected to result in a 3:1 phenotypic ratio, with three-quarters of the offspring displaying the dominant phenotype and one-quarter displaying the recessive phenotype.
What proportion of the offspring from this cross will have smooth yellow peas?
Since smooth yellow peas are dominant traits (represented by genotypes RRYY or RRYy), all offspring from a cross between two plants with smooth yellow peas will also have smooth yellow peas. Therefore, 100% of the offspring will have this phenotype.
When a cross between a red flower and a white flower yeilds pink offspring the trait is?
Incomplete dominance, where the heterozygous phenotype is an intermediate blend of the two homozygous phenotypes.
What is the expected phenotype ratio of seed color of the offspring of an F1 x F1 cross?
The expected phenotype ratio of seed color in the offspring of an F1 x F1 cross is 3:1. This is because the F1 generation is heterozygous for the trait, resulting in a 3:1 ratio of dominant to recessive phenotypes in the offspring.
If R is dominant to r the offspring of the cross of RR with rr will be homozygous?
R R r Rr Rr r Rr Rr That is the Punnet Square. The genotype will be 100% Rr in the cross. The phenotype will be whatever phenotype is constituted by your dominant allele.
What is a testcross?
A testcross is a genetic cross between an individual with a dominant phenotype but unknown genotype and a homozygous recessive individual. This cross is used to determine the genotype of the first individual by observing the phenotypic ratios of the offspring.
What word describes the offspring of a cross between parents with different traits?
The offspring of a cross between parents with different traits is called a hybrid.
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 the name of the offspring of a first cross?
The offspring of a first cross between two different breeds or species is known as a hybrid.
Which genotype is used in a test cross?
In a test cross, one individual with a dominant phenotype but unknown genotype is crossed with a homozygous recessive individual. The genotype of the individual with the dominant phenotype can then be inferred based on the phenotypic ratios of the offspring.
What is the name for a cross between an individual of unknown genotype and a homozygous recessive?
A cross between a homozygous recessive and an individual of unknown genotype is called a test cross.The homozygous recessive can only pass on a recessive allele to the offspring, and so any recessive in the other parent will show up in the phenotype (detectable characteristics) of some of the offspring.
If a homozygous dominant is crossed with a homozygous recessive for a given trait the offspring will be?
The phenotype will show the dominant trait. All dominant traits mask recessive ones; If the genotype is heterozygous (One dominant and one recessive) the organism's phenotype will be dominant.
