All individuals who express a dominant trait possess at least one dominant allele for that specific trait. This means that even if they carry a recessive allele, the dominant trait will be expressed phenotypically. Dominant traits can mask the presence of recessive traits, leading to a variety of observable characteristics in a population. Examples include traits like brown eyes or curly hair, which can be passed on to offspring regardless of the recessive alleles they may carry.

How would a baby change if one parent was homozygous dominant for all the traits and the other parent was heterozygous?
If one parent is homozygous dominant for all traits (carrying two dominant alleles for each trait), and the other parent is heterozygous (carrying one dominant and one recessive allele for each trait), there would be a 100% chance that the baby would inherit the dominant alleles from the homozygous dominant parent. Therefore, the baby would also be heterozygous for all the traits, carrying one dominant and one recessive allele for each trait.
If an animal with 2 dominant genes for a trait has offspring with an animal with 2 recessive genes for same trait their offspring can only have what?
Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.
Why were all of the F1 plants of Mendel's peas were tall?
All of the F1 plants of Mendel's peas were tall because the tall trait was dominant over the short trait. Mendel crossed purebred tall peas (TT) with purebred short peas (tt), resulting in F1 offspring that all inherited one tall allele from each parent (Tt). Since the presence of just one dominant allele (T) is enough to express the tall phenotype, all F1 plants exhibited the tall trait.
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.
How would the smiley face change if one parent were homozygous dominant for all the traits while the other was heterozygous?
If one parent is homozygous dominant for all traits, they can only pass on dominant alleles, while the heterozygous parent can pass on either dominant or recessive alleles. This would result in a combination of offspring that are either homozygous dominant or heterozygous for each trait, but none would be homozygous recessive. Consequently, the overall phenotype of the smiley face would predominantly express the dominant traits.
Father with homozygous genes for dominant trait?
This means that the father has two copies of the dominant allele for a particular trait. As a result, all of his offspring will inherit at least one copy of the dominant allele from him. This implies that all his offspring will either express the dominant trait or be carriers of the dominant allele.
How can you use dominant trait in a sentence?
The dominant trait for eye color in humans is brown, which means that if one parent has brown eyes and the other has blue eyes, the child is more likely to inherit brown eyes due to the dominant trait.
What does it mean to have a dominant trait?
In genetics, a trait is considered dominant when it determines a phenotype over a recessive trait. For example, AA is crossed with AA to make Aa, Aa, Aa, and Aa. If "A" is the dominant trait and "a" is the recessive trait, then since this cross produces heterozygous progeny, they will all show the dominant phenotype. A dominant trait is just how it sounds, it dominates over recessive traits when they are both present.
A red-eyed fly mates with a blue-eyed fly. The offspring all have red eyes. What is the dominant trait?
A dominant trait, when present, is always expressed. So if the offspring of a red eyed and blue eyed mating are all red, then red must be dominant because it is the trait expressed.

Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.
What would you expect if you breed or mate 2 different true breeding stocks of plants?
If one trait is dominant over the other, then you would expect all of the offspring to have the dominant trait.
What is the dominant trait when a red-eyed fly mates with a blue-eyed fly resulting in offspring that all have red eyes?
A dominant trait, when present, is always expressed. So if the offspring of a red eyed and blue eyed mating are all red, then red must be dominant because it is the trait expressed.

What is the result of a cross between an individual who is homozygous dominant and another who is homozygous recessive for a trait?
All the offspring will be heterozygous with a phenotype showing the dominant trait. Let the alleles be H (dominant) and h (recessive). All the gametes from the first individual will be H, and from the other, h. Thus all the offspring must be Hh.
How many dominant alleles are required in a genotype to show the dominant phenotype?
If the allele is dominant, you only need one copy for it to be expressed in the phenotype (you have TWO alleles for each trait) If the allele is dominant, you only need one copy for it to be expressed in the phenotype (you have TWO alleles for each trait)
What is meant by dominance and recessiveness?
First of all alleles code for different traits all across an organism. Simply looking at it, a dominant allele is a trait that essentially "dominates" or is expressed over a recessive allele. In theory every organism (that is not asexual) receives one allele from its father and one allele from its mother. If both of these alleles are dominant (homozygous dominant) than the dominant trait is expressed, if one is dominant and one is recessive (heterozygous) than still the dominant trait is expressed. However, if the alleles for both traits are recessive (homozygous recessive) than the recessive trait will be expressed.
