How do you distinguish between genotype and phenotype heterozygous and homozygous and dominant and recessive?
Genotype is the organism's full heredity information that may or may not be expressed. Actual observed properties are the phenotype. The phenotype is dependent on the genotype.
Genes are homozygous when the same allele (form of the gene) inherited from both parents is the same. When different forms of the same gene are inherited from parents, they are heterozygous.
Dominance refers to the relation between alleles of a gene. When two alleles of a gene combine, the dominant one then determines the trait that is expressed. In order for a recessive trait to be expressed, both alleles need to be recessive.
What else can I help you with?
In crossing a homozygous recessive with a heterozygote what is the chance of getting a homozygous recessive phenotype in the F1 generation?
1/2 or 50%. The homozygous recessive gentoype contains two recessive alleles for the gene for a trait. So the homozygous recessive individual can pass on only recessive alleles to an offspring. The heterozygous individual has one dominant and one recessive allele for the gene for a trait. So the heterozygous individual can pass on either a dominant or a recessive allele to an offspring. So if an offspring inherits a recessive allele from the heterozygous parent, along with the recessive allele from the homozygous recessive parent, it will have the homozygous recessive genotype and phenotype.
What is the differences between homozygous dominant and homozygous recessive and heterozygous?
Homozygous dominant individuals have two copies of the dominant allele for a trait, homozygous recessive individuals have two copies of the recessive allele, and heterozygous individuals have one copy of each allele. Homozygous dominant and heterozygous individuals will express the dominant trait, while homozygous recessive individuals will express the recessive trait.
What phenotype is produce by each of the following genotypes?
Genotype: AA - The phenotype is homozygous dominant, exhibiting the dominant trait. Genotype: Aa - The phenotype is heterozygous, exhibiting the dominant trait. Genotype: aa - The phenotype is homozygous recessive, exhibiting the recessive trait.
What is the phenotype of a flower in a pea plant that is homozygous recessive?
You would expect 1 homozygous dominant, 2 heterozygous dominant and 1 homozygous recessive offspring. This is because each parent has one dominant and one recessive allele. Therefore there is a 75% chance of a dominant phenotype and a 25% chance of a recessive phenotype.
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is?
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is homozygous recessive. A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotype ratio is 3 dominant 1 recessive.
In crossing a homozygous recessive with a heterozygote what is the chance of getting a homozygous recessive phenotype in the F1 generation?
1/2 or 50%. The homozygous recessive gentoype contains two recessive alleles for the gene for a trait. So the homozygous recessive individual can pass on only recessive alleles to an offspring. The heterozygous individual has one dominant and one recessive allele for the gene for a trait. So the heterozygous individual can pass on either a dominant or a recessive allele to an offspring. So if an offspring inherits a recessive allele from the heterozygous parent, along with the recessive allele from the homozygous recessive parent, it will have the homozygous recessive genotype and phenotype.
What is the differences between homozygous dominant and homozygous recessive and heterozygous?
Homozygous dominant individuals have two copies of the dominant allele for a trait, homozygous recessive individuals have two copies of the recessive allele, and heterozygous individuals have one copy of each allele. Homozygous dominant and heterozygous individuals will express the dominant trait, while homozygous recessive individuals will express the recessive trait.
What is crossing a homozygous dominant or homozygous recessive with a heterozygous?
There is a 50% chance of a homozygous dominant and a 50% chance of a heterozygous.
What phenotype is produce by each of the following genotypes?
Genotype: AA - The phenotype is homozygous dominant, exhibiting the dominant trait. Genotype: Aa - The phenotype is heterozygous, exhibiting the dominant trait. Genotype: aa - The phenotype is homozygous recessive, exhibiting the recessive trait.
How do two heterozygous organisms produce on offspring with a recessive phenotype?
There are two forms of Homozygous inheritance: Homozygous Dominant, and Homozygous Recessive. In order for two parents that are Homozygous to produce a Heterozygous offspring, one of them MUST be Homozygous Dominant, and the other MUST be Homozygous Recessive.
What is the phenotype of a flower in a pea plant that is homozygous recessive?
You would expect 1 homozygous dominant, 2 heterozygous dominant and 1 homozygous recessive offspring. This is because each parent has one dominant and one recessive allele. Therefore there is a 75% chance of a dominant phenotype and a 25% chance of a recessive phenotype.
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is?
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is homozygous recessive. A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotype ratio is 3 dominant 1 recessive.
How many phenotypes can come from a heterozygous parent and a homozygous recessive parent?
Two types: A heterozygous parent (Aa) and a homoygous recessive parent (aa) can produce phenotypically dominate and phenotpically recessive offspring (with 50% genotypes Aa and the other 50% aa). If the genes are co-dominate then the offspring can have blended traits and recessive traits phenotypically.
What are the genotype and phenotype ratios in offspring from two heterozygous parents?
The genotype ratio is 1:2:1 (1 homozygous dominant, 2 heterozygous, 1 homozygous recessive) and the phenotype ratio is 3:1 (3 individuals showing the dominant trait, 1 individual showing the recessive trait).
Do Parents with the dominant phenotype cannot have offspring with the recessive phenotypeous for a trait that is?
No. Parents with the dominant phenotype might be heterozygous in their genotype. This means they could carry both the dominant and recessive allele for a trait. So they could both pass the recessive allele to an offspring, who would then have the homozygous recessive genotype and recessive phenotype.
What is the percentage of offspring that will exhibit the dominant trait from A crossing of A homozygous dominant and homozygous recessive individual?
The homozygous dominant individual can only pass on the dominant allele and the homozygous recessive individual can only pass on the recessive allele, therefore all offspring will be heterozygous and have the dominant phenotype.
Is it true that people who are heterozygous recessive allele but who have a normal phenotype eill not pass the harmful recessive allele to their kids?
It depends on the genotype of the childs other parent. If your partner is heterozygous as well then there is a 25% chance your child will be homozygous recessive. If they are homozygous dominant then none of your children will have the phenotype of the recessive trait. They will just possibly be carriers of the recessive allele.
