What are two allele combination of two individuals who are true breeding for the height characteristics in pea plants?
True breeding pea plants for height typically exhibit homozygous alleles, meaning they have two identical alleles for the trait. For height, this could be represented as either "TT" for tall plants or "tt" for short plants, where "T" is the dominant allele for tallness and "t" is the recessive allele for shortness. Therefore, the two allele combinations for two true breeding individuals would be "TT" and "tt".

How is the hybrid in the allele observed?
A hybrid allele with traits from both parents is observed when an organism inherits different forms of a gene from each parent. This can result in a unique combination of genetic traits, leading to variation in physical characteristics or traits within the organism.
Which form of selective breeding crosses parents with the same or similar sets of allele?
Inbreeding!
What is the genotype of a pure-breeding myopic person?
A pure-breeding myopic person, who consistently passes on the myopic trait to their offspring, would typically have a genotype that is homozygous for the myopia allele. This means they would have two copies of the allele associated with myopia, often represented as "mm" if "M" represents the normal vision allele and "m" represents the myopia allele. Thus, their genotype would be "mm."
What does an Allele do?
An allele is a variant form of a gene that can determine specific characteristics or traits in an organism. Alleles can be dominant or recessive, and they contribute to genetic diversity within a population. The combination of alleles inherited from parents influences an individual's phenotype.
What ratio of allele combination do you observe?
The allele combinations observed in individuals are determined by the genetic variations they inherit from their parents. The ratio of allele combinations in a population would depend on the frequencies of different alleles present in that population and the patterns of inheritance of those alleles. These ratios can vary depending on the specific genetic traits being studied.
What is a fixed allele.?
An allele present in all members of a population
What is the significance of the allele combination of an organism in determining its genetic traits and characteristics?
The allele combination of an organism is significant because it determines the genetic traits and characteristics that the organism will have. Alleles are different forms of a gene that can influence traits like eye color or height. The specific combination of alleles that an organism inherits from its parents will determine its physical appearance and other characteristics.
What is an example of allele frequency?
An example of allele frequency is when in a population of 100 individuals, 60 individuals have the dominant allele (A) for a specific gene, while 40 individuals have the recessive allele (a). The frequency of the dominant allele (A) would be 0.6, and the frequency of the recessive allele (a) would be 0.4.
How is the hybrid in the allele observed?
A hybrid allele with traits from both parents is observed when an organism inherits different forms of a gene from each parent. This can result in a unique combination of genetic traits, leading to variation in physical characteristics or traits within the organism.
What describes an allele whose characteristics phenotype is masked by the presence of a second different allele?
Recessive
Why is a dominant allele called dominant apex?
because it dominates the phenotype
Which form of selective breeding crosses parents with the same or similar sets of allele?
Inbreeding!
What type of allele is masked when a dominant allele is present?
The recessive allele is masked when a dominant allele is present. Dominant alleles are expressed over recessive alleles in heterozygous individuals.
What does an Allele do?
An allele is a variant form of a gene that can determine specific characteristics or traits in an organism. Alleles can be dominant or recessive, and they contribute to genetic diversity within a population. The combination of alleles inherited from parents influences an individual's phenotype.
The allele for the sickle cell trait is what with the normal allele?
The allele for the sickle cell trait is codominant with the normal allele. This means that in individuals with both alleles present, both traits are expressed.
1 in drosophila the allele for normal length wings is dominant over the allele for vestigial wings In populations of 1000 individuals 360 show the recessive phenotype How many individuals would you?
160 homozygous dominant individuals and 480 heterozygous individuals
The genetic disease blue sclera is determined by an autosomal dominant allele The eyes of individuals with this allele have bluish sclera These same individuals may also suffer from fragile bones an?
