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.
In a hybrid individual the trait that is covered and not expressed is the what trait?
recessive
Is the punnet square used to find the probability of genotypes and phenotypes?
A Punnet square is used to find the probablitiy of certain genetic traits in the offspring of an organism (example: the traits in the children) by taking the trait of each possible parent gamete (sex cell) and combining the combinations within the squares.Example:A aA AA Aaa Aa aaSo the offspring here have a 25% chance of being homozygous (both dominant) dominant for the trait, 50% heterozygous (one dominant and one recessive) dominant for the trait, and 25% (homozygous (both recessive)) recessive for the trait.
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 an allele that produces a trait in the heterozygous condition called?
An allele that produces a trait in the heterozygous condition is called dominant. This means that only one copy of the allele is needed to express the trait.
Would the genotypes AA and AA express a dominant trait?
yes.
What genotypes covers up other traits?
dominant 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.
A plant can have either wide (W) or narrow (w) leaves. Wide leaves are the dominant trait. Which of the following genotypes will lead to a recessive phenotype?
Ww
In a hybrid individual the trait that is covered and not expressed is the what trait?
recessive
What is homozygous dominate heterozygous and homozygous recessive look like?
Homozygous dominant individuals carry two identical dominant alleles (e.g., AA) and typically express the dominant trait. Heterozygous individuals have one dominant and one recessive allele (e.g., Aa), exhibiting the dominant trait while carrying the recessive one. Homozygous recessive individuals possess two identical recessive alleles (e.g., aa) and express the recessive trait. The phenotypic expressions of these genotypes depend on the specific traits being studied.
How many possible genotypes and phenotypes are there for a single gene trait that shows dominance in any given population?
For a single gene trait with two alleles, one dominant and one recessive, there are three possible genotypes: homozygous dominant (AA), heterozygous (Aa), and homozygous recessive (aa). In terms of phenotypes, there are typically two: the dominant phenotype (AA and Aa) and the recessive phenotype (aa). Thus, there are three genotypes and two phenotypes for this trait in the population.
If curly hair (C) is a dominant trait what are the genotypes of the parents in the pedigree?
In a pedigree where curly hair (C) is a dominant trait, the genotypes of the parents can vary. If at least one parent has curly hair, their genotype could be either CC (homozygous dominant) or Cc (heterozygous). If both parents have straight hair (which is the recessive trait), their genotype must be cc. To determine the specific genotypes of the parents more accurately, you would need to analyze the phenotypes of their offspring in the pedigree.
What are the possible genotypes for dwarfism?
There are many types of dwarfism. Acondroplastic dwarfism is a dominant trait. Living individuals are heterozygous for the trait as a homozygous dominant individuals have substantial skeletal anomalies that result in death in infancy.
Is Aa and AA a dominant phenotype?
Yes, both Aa and AA genotypes represent the dominant phenotype for a specific trait. The presence of at least one dominant allele (A) will result in the dominant phenotype being expressed.
What is a all Ww Offspring?
All Ww offspring refer to the genetic outcome of a cross between two organisms where one is homozygous dominant (WW) and the other is heterozygous (Ww) for a particular trait. In this scenario, the possible genotypes of the offspring would be either WW or Ww. Thus, all offspring would display the dominant trait associated with the W allele, but 50% would be homozygous (WW) and 50% heterozygous (Ww). Therefore, all offspring would express the dominant phenotype, but their genotypes would vary.
What does it mean that an organism is homozygous dominant for a trait?
Homozygous Dominant for a trait means that an organism has two dominant alleles for that trait. Here's an example: Trait: Widow's Peak Widow's Peak allele: Dominant (D) No widow's peak allele: Reccessive(d) Homozygous Dominant (DD) Homozygous Reccessive (dd) Heterozygous (Dd)
