How are the results of the crosses differ if the red allele was dominant over the white allele explain both F1 and F2 generations?
Answer: When red allele dominant over the white allele then the dominant character hifes the characteristics of recessive one.In F1 generation Pink is 100% and in F2 generation Red is 25% and Pink is 50% because of phenotype and genotype.
How the red and white alleles can interact with one another?
This type of allelic relationship was termed codominance. It appears as if the red and white alleles are interacting in the heterozygote to generate the pink flowers. Another example of codominance can be seen by looking at a biochemical phenotype.
Is red a dominant allele?
The gene for red hair is recessive, so a person needs two copies of that gene for it to show up or be expressed. That means even if both parents carry the gene, just one in four of their children are likely to turn out to be a redhead.
What is the difference between dominant gene and recessive gene?
What is the difference between dominant and recessive traits? Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
What is the difference between F1 and F2 crosses and why are both crosses necessary?
The term “F1” means the “first filial generation,” or the initial cross between two genetically distinct plants. … An “F2″ cross is the next generation, or the result of crossing two sister seedlings from the F1 cross. Selfing an F1 plant produces an F2 also.
How can alleles interact with one another?
Alleles of a single gene can interact with other alleles of the same gene or with the environment. When heterozygous offspring look like one parent but not the other – •complete dominance, dominance series. When heterozygotes show a phenotype unlike that of either parent – •incomplete dominance.
What type of interaction is occurring between the two genes?
Genetic interaction is the set of functional association between genes. One such relationship is epistasis, which is the interaction of non-allelic genes where the effect of one gene is masked by another gene to result either in the suppression of the effect or they both combine to produce a new trait (character).
What does it mean when a trait is dominant?
Dominant: A genetic trait is considered dominant if it is expressed in a person who has only one copy of that gene. (In genetic terms, a dominant trait is one that is phenotypically expressed in heterozygotes).
What do you mean by dominant alleles?
Definitions of dominant allele. an allele that produces the same phenotype whether its paired allele is identical or different. synonyms: dominant.
