Why would defective recessive alleles be retained in the gene pool?

They don't express in heterozygous condition ,hence remain in gene pool .

Defective recessive alleles can be retained in the gene pool because they may not affect individuals who are carriers of the allele (heterozygotes). Additionally, in small populations, genetic drift can lead to the retention of defective alleles. Finally, if the defective allele provides a selective advantage in certain environmental conditions, it may persist in the population.

When a plant has Two recessive alleles for wrinkled seeds how would you write the symbols for its alleles?
well it depends on the letters that you are given, recessive alleles are ALWAYS lower case.An example answer would be: ss, where s would represent the recessive allele.
What alleles would a homozygous recessive organism have?
A homozygous recessive organism would have two copies of the same recessive allele for a particular gene. This means that both alleles carried by the organism would be the recessive form.
Are organisms with alleles BB recessive or dominant?
Organisms with alleles BB are considered homozygous dominant. This means that the dominant allele (B) is expressed in the phenotype. Dominant alleles mask the effects of recessive alleles in heterozygous individuals.
What is it when an allele is neither dominant nor recessive?
When an allele is neither dominant nor recessive, it means that both alleles equally influence the trait. This is known as codominance, where both alleles are expressed in the phenotype of the individual.
How would you describe the alleles in a heterozygous genotype?
In a heterozygous genotype, an individual possesses two different alleles for a particular gene, with one being dominant and the other recessive. The dominant allele is expressed in the phenotype, while the recessive allele is not unless two recessive alleles are present.
What alleles is the recessive alleles explain why?
it would be t recie
When a plant has two recessive alleles for short stems its alleles are written?
well it depends on the letters that you are given, recessive alleles are ALWAYS lower case.An example answer would be: ss, where s would represent the recessive allele.

A homozygous recessive organism would have two copies of the same recessive allele for a particular gene. This means that both alleles carried by the organism would be the recessive form.
How do you represent alleles?
Alleles are typically represented using letters, with uppercase letters representing dominant alleles and lowercase letters representing recessive alleles. For example, for a gene where 'A' is the dominant allele and 'a' is the recessive allele, an individual that carries one of each allele would be represented as 'Aa'.
Are organisms with alleles BB recessive or dominant?
Organisms with alleles BB are considered homozygous dominant. This means that the dominant allele (B) is expressed in the phenotype. Dominant alleles mask the effects of recessive alleles in heterozygous individuals.
What is it when an allele is neither dominant nor recessive?
When an allele is neither dominant nor recessive, it means that both alleles equally influence the trait. This is known as codominance, where both alleles are expressed in the phenotype of the individual.
Gene pairs consists of two dominant alleles or two recessive alleles?
Actually, gene pairs can consist of two dominant alleles, two recessive alleles, or one dominant and one recessive allele. The combination of alleles in a gene pair determines the specific trait expressed by an individual.
How would you describe the alleles in a heterozygous genotype?
In a heterozygous genotype, an individual possesses two different alleles for a particular gene, with one being dominant and the other recessive. The dominant allele is expressed in the phenotype, while the recessive allele is not unless two recessive alleles are present.
A recessive allele is represented by an letter?
In genetics, a recessive allele is typically represented by a lowercase letter. For example, if the dominant allele is represented by "A", the recessive allele for the same trait would be represented by "a".
What is the expected frequency for a person to have all six recessive characteristic?
The expected frequency for a person to have all six recessive characteristics would be very low, as it would require inheriting two recessive alleles for each of the six traits. This would be a rare occurrence due to the probability of inheriting multiple recessive alleles for each trait from both parents.
How do dominant and recessive alleles affect an offsprings phenotype?
Dominant alleles mask the effects of recessive alleles in heterozygous individuals, so only the dominant allele's phenotype is expressed. Recessive alleles are only expressed when an individual is homozygous for that allele. This means that dominant alleles typically determine the phenotype when present, while recessive alleles only show their effects when no dominant allele is present.
