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.
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.
An organism that is homozygous for many recessive traits may be at a disadvantage due to the expression of those recessive traits. These traits may negatively impact the organism's overall fitness, making it less well-adapted to its environment compared to organisms that do not have as many recessive traits expressed.
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.
In this cross, the homozygous recessive organism has a genotype of "aa," where "a" represents the recessive allele. The unknown organism, which we can denote as "A?" (where "A" represents the dominant allele), must be heterozygous ("Aa") to produce offspring with both dominant and recessive traits. When crossed (aa x Aa), the resulting offspring would be 50% "Aa" (exhibiting the dominant trait) and 50% "aa" (exhibiting the recessive trait). Thus, the genotype and phenotype ratios confirm the unknown organism is heterozygous.
The trait received is recessive.

Recessive traits can be hidden if the organism inherits one dominant and one recessive allele (i.e. is heterozygous) for a gene. If a heterozygous organism mates with another heterozygous organism for the same trait, the recessive trait may be expressed in their offspring, which would mean that the offspring inherited two recessive alleles, one from each parent.

No, the offspring of identical parents would not always look like the parents because everyone has dominant and recessive traits, where the recessive traits do not show but is still in DNA. That said, recessive traits not shown in parents can be passed on as dominant traits to offspring - making offspring not always identical to its parents. (this is also called genetic variation)

They pass on traits. There are recessive traits and dominant traits. The dominant trait is normally the one that overpowers recessive

The traits an organism displays is a result of their genetics. Recessive traits tend to not show in many organisms.
The trait received is recessive.
Purebred.
Recessive traits were visible in the F2 generation of Mendel's experiments, where the offspring of the F1 generation showed a 3:1 ratio of dominant to recessive traits.
An organism's unseen recessive genes are included in its genotype, which is the complete set of genetic information inherited from its parents. While these recessive alleles may not be expressed in the organism's phenotype (the observable traits), they can still be passed to offspring. If an organism carries two copies of a recessive allele, or one copy alongside a dominant allele that does not mask it, the trait can become visible in subsequent generations. Thus, recessive genes play a crucial role in inheritance and genetic variation.
