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
How are traits categorized for the offspring?
As traits are dispensed to the offspring they can be either dominant or recessive. A recessive trait is only expressed when two identical alleles exist.
How do offspring inherit their traits from parents?
Offspring inherit traits from their parents through genes, which are segments of DNA that determine specific characteristics. Each parent contributes half of their genetic material to the offspring, resulting in a unique combination of traits. This process of genetic inheritance determines the physical and behavioral traits of the offspring.
Why is lamarck's theory not supported by the theory of natural selection?
Lamarck thought that traits organisms acquired during their lifetime would be passed on to offspring. He believed that traits were determined by use or disuse. However, acquired traits cannot be passed on to offspring; only traits determined by DNA can
How will the offspring compare to the parent in term of traits and genetics materials?
the child has only one parent so the offspring will look exactly like the parent.
Selection in which humans allow only the best organisms to produce offspring?
Selective breeding allows humans to choose desirable traits in organisms and only allow those with the best traits to reproduce. This process is used to create new breeds or varieties with specific characteristics in plants and animals. It can lead to the development of organisms that are better suited for certain purposes, such as increased productivity or improved health.
Can only organisms with dominant traits breed?
No, organisms with recessive traits can also breed. Both dominant and recessive traits are passed on through alleles from parents to offspring, regardless of whether the traits are expressed in the parent organism. As long as there is genetic compatibility, any organism can breed, though the offspring may express different combinations of traits.
What are characteristics of sex-linked traits?
Sex-linked traits are usually passed from mother to son by a defective gene on the X chromosome.Three examples of sex-linked traits are:Color blindnessHemophiliaBaldness
Are recessive traits are always shown in an organism offspring?
No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.
Are Recessive traits always shown in an organism's offspring?
No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.
Why is it that lamarck's suggestion that organisms arise spontaneously and then become increasingly more complex is not supported by the theory of natural selection?
Because lamarck thought that traits organisms aquired during their lifetime would be passed on to offspring. He believed that traits were determined by use or disuse. However, aquired traits cannot be passed on to offspring, only traits determined by DNA can.
Traits that typically will only be expressed in offspring if they inherit two copies of the genes for that trait is called what?
Recessive traits. This means that the trait is only expressed when an individual inherits two copies of the recessive allele for that trait, one from each parent.
