Do gametes have two alleles per trait and organisms have one?
Gametes have one allele per trait, as they are haploid cells with half the normal number of chromosomes. Organisms are typically diploid and have two alleles per trait, one from each parent. Each gamete carries only one allele which then combines during fertilization to restore the diploid number of chromosomes in the offspring.
A trait which always appears when it is present is called what kind of trait?
A trait that always appears when it is present is called an obligate trait. This means that the trait is consistently expressed whenever the underlying genetic or environmental conditions are present.
The detectable traits of an organism as determined by what alleles are present is the what?
The detectable traits of an organism as determined by what alleles are present is the phenotype. Phenotype is the observable characteristics of an organism, such as its physical appearance or behavior, which are influenced by both genetic and environmental factors.
What was medels specific law where a diploid organism transfers only one allele to its gametes?
Mendel's Law of Segregation states that a diploid organism carries two alleles for each gene, but only passes on one allele to each offspring. This process ensures genetic diversity and the random assortment of alleles into gametes.
When is the only time a recessive trait appears on a organism?
A recessive trait only appears in an organism when it is homozygous for that trait, meaning it has two copies of the recessive allele. This occurs when an organism inherits the recessive allele from both parents.
What is a trait that is not expressed when an organism receives genes for 2 different forms of a trait?
A trait that is not expressed when another is present is referred to as a recessive trait.
What is one set of instructions for an inherited trait?
The gametes (sex cells) that combine to form a new organism in sexual reproduction each contain one set of the instructions for the genes of the new organism, that is, one set each for each trait.
Which is the dominant allele?
The dominant allele is the trait that shows up in the organism when the allele is present
What is an organism with two genes for a trait called?
An organism with two like alleles for a trait is homozygous for that trait.
Do gametes have two alleles per trait and organisms have one?
Gametes have one allele per trait, as they are haploid cells with half the normal number of chromosomes. Organisms are typically diploid and have two alleles per trait, one from each parent. Each gamete carries only one allele which then combines during fertilization to restore the diploid number of chromosomes in the offspring.
What is a organism that has two different allels for a trait?
an organism that has two different alleles for a trait is heterozygous
What is the name of the trait that an organism develops after its born?
Acquired Trait
A trait which always appears when it is present is called what kind of trait?
A trait that always appears when it is present is called an obligate trait. This means that the trait is consistently expressed whenever the underlying genetic or environmental conditions are present.
What is a derived trait?
A derived trait is a characteristic that is present in an organism, group of organisms, or species as a result of evolutionary changes or adaptations from its ancestral form. It is a feature or attribute that has evolved over time and is unique to a particular lineage or group of organisms.
The detectable traits of an organism as determined by what alleles are present is the what?
The detectable traits of an organism as determined by what alleles are present is the phenotype. Phenotype is the observable characteristics of an organism, such as its physical appearance or behavior, which are influenced by both genetic and environmental factors.
What is the name for a characteristic such as an eye color of an organism?
This could be called a trait (inheritance).
Mendel's law of segregation states that an organism inherits two alleles for any given trait one from each parent?
Mendel's law of segregation states that each organism carries two alleles for a trait, one from each parent, and during gamete formation, these alleles segregate randomly into separate gametes. This results in each gamete carrying only one allele for a given trait.
