The expression of a recessive trait occurs when two recessive alleles recombine.
I'm going to use an example for this. Let's say that blue hair is recessive, and black hair is dominant.
B = Black hair
b = Blue hair
If you have the parents:
Parent 1: Bb (Has black hair; it dominates blue hair... but is a carrier of the blue hair gene.)
Parent 2: bb (Has blue hair; only recessive genes are present)
If you use a punnet square,
They have four possible combinations of kids:
Kid 1: Bb (Black haired; is a carrier of blue hair)
Kid 2: Bb (Black haired; is a carrier)
Kid 3: Bb (Black haired; is a carrier)
Kid 4: bb (Blue haired)
These "carriers" are able to have a chance of producing a child with the same recessive gene, whether it be displayed or just carried.
It's very confusing, but simple once you get the hang of it. :3
What else can I help you with?
When is a recessive allel expressed in offspring?
A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.
How can an offspring show a trait that is not displayed in either of the parents?
dominant and recessive genes say the mom had black hair and her mom had blond hair and the dad had black hair and his mom had red hair if the baby had red or blond hair the parents had those as recessive genes its all about ancestry and genes. PS I'm an 11 year old middle scholar
What is the process of the transmission of characteristics from parent to offspring?
The transmission of characteristics from parent to offspring occurs through the passing down of genes from parents to their offspring. Genes are units of heredity that carry instructions for various traits. Offspring inherit a combination of genes from both parents, which determines their physical characteristics and traits.
What type of alleles are expressed only if two identical copies exist on the homologs of the offspring?
Recessive alleles are expressed only when two identical copies exist on the homologs of the offspring. In this case, if an individual inherits two copies of the recessive allele, it will show the recessive trait.
Traits that typically will only be expressed in offspring if they inherit two copies of the genes for the trait are called?
Traits that typically will only be expressed in offspring if they inherit two copies of the genes for the trait are called Recessive traits. - Nikkkki
If an animal with 2 dominant genes for a trait has offspring with an animal with 2 recessive genes for same trait their offspring can only have what?
Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.
Are dominante and recessive genes responsibile for how baby looks?
Yes, dominant and recessive genes play a role in determining physical traits in offspring. Dominant genes are more likely to be expressed in the phenotype, while recessive genes are typically masked unless an individual inherits two copies of the recessive allele. This interplay between dominant and recessive genes contributes to the variety of physical characteristics seen in offspring.
What is the probability that an offspring will be homozygous recessive?
well, it depends on the genes of the parents
What did mendel hypothesis as a result of his experiments?
Genes for different traits are inherited independently of one another.
When is a recessive allel expressed in offspring?
A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.
How can an offspring show a trait that is not displayed in either of the parents?
dominant and recessive genes say the mom had black hair and her mom had blond hair and the dad had black hair and his mom had red hair if the baby had red or blond hair the parents had those as recessive genes its all about ancestry and genes. PS I'm an 11 year old middle scholar
Is it true carriers of genetic diseases who do not have the disease themselves have recessive genes for the disorder?
Yes. They can pass it on to their offspring.
Why do the recessive genes do not disappear from the population?
Recessive genes can persist in a population because they can be carried in individuals without being expressed. These hidden recessive genes can be passed down through generations, only showing up if inherited from both parents. Additionally, genetic diversity can help maintain recessive genes in a population even if they are not expressed in every generation.
How are recessive genes kept in the gene pool?
Recessive genes are kept in the gene pool through carriers who may not exhibit the trait themselves but can pass it on to their offspring. These carriers contribute to genetic diversity in the population, ensuring that recessive traits are preserved even when not expressed.
A plant with two recessive genes for height is crossed with a plant with one dominant and one recessive gene for height What genes will their offspring have?
hh X Hh You get two recessives; hh and hh and two heterozygous plants; Hh and Hh
What table is used to identify dominant and recessive genes?
The Punnett square is a table used to predict the possible genotypes of offspring in a genetic cross between two parents. It is commonly used to determine dominant and recessive genes in offspring based on the genotypes of the parents.
What is the process of the transmission of characteristics from parent to offspring?
The transmission of characteristics from parent to offspring occurs through the passing down of genes from parents to their offspring. Genes are units of heredity that carry instructions for various traits. Offspring inherit a combination of genes from both parents, which determines their physical characteristics and traits.
