In which offspring does a dominant trait appear?
if a trait is recessive, it can only be expressed if its other trait is recessive as well. If the other trait in the genotype is dominant, it will block the recessive factor. But if both are recessive, they will be able to be seen in the offspring.
If about 50 percent of the offspring have the dominant phenotype and 50 percent have the recessive phenotype what are the genotype of the parents?
If the phenotype is recessive then the genotype must be dd.
What is a dominat trait dictionary?
A dominant trait is part of genetics in which a trait will appear in an offspring if one parent contributes it. For example, if one parent contributes the dominant trait of dark hair and the other contributes the recessive trait of light hair, the offspring would have dark hair.
What will have only two possible phenotypes?
Any cross of parents for a single trait where the dominant allele completely masks any expression of the recessive allele as follows:Parents are both heterozygous for the trait. For example Aa X Aa produces 75% of offspring with the dominant phenotype and 25% with the recessive phenotype.One parent is heterozygous for the trait and the other parent is homozygous recessive. For example: Aa X aa produces 50% offspring with the dominant phenotype and 50% offspring with the recessive phenotype.If the trait is co-dominant/non-dominant a heterozygote would have the median characteristic and a homozygote could be either of two phenotypes. If T is tall and t is short the Tt offspring would bemedium in this example. The way to produce offspring with only two phenotypes would be to cross a heterozygous parent with a homozygous parent. For Example:Tt X tt cross would produce 50% tt (short) offspring and 50% Tt (medium) offspring. A TT X Tt cross would produce 50% TT (tall) offspring and 50% Tt (medium) offspring.
Do you get your eye color from your parent?
Yes you get your eye color from your parent. The parent that carries one dominant gene and one recessive gene for a specific eye color and the other parent carries two recessive genes for a different eye color, you will get the eye color of the parent who carries the dominant and recessive gene. In other words, the dominant gene trumps the recessive gene. In another scenario, if both parents carry two recessive genes for a specific eye color, then you will inherit the recessive gene of that color.
If one parent has the genotype Cc for hair color and the other parent has the genotype cc what percentage of the offspring will have the recessive genotype for hair color?
25% of the offspring will have the recessive genotype for hair colour.
How do two heterozygous organisms produce on offspring with a recessive phenotype?
There are two forms of Homozygous inheritance: Homozygous Dominant, and Homozygous Recessive. In order for two parents that are Homozygous to produce a Heterozygous offspring, one of them MUST be Homozygous Dominant, and the other MUST be Homozygous Recessive.
How many phenotypes can come from a heterozygous parent and a homozygous recessive parent?
Two types: A heterozygous parent (Aa) and a homoygous recessive parent (aa) can produce phenotypically dominate and phenotpically recessive offspring (with 50% genotypes Aa and the other 50% aa). If the genes are co-dominate then the offspring can have blended traits and recessive traits phenotypically.
To produce pea plat that only display the recessive phenitypw of a trait what must be the genotypes of the parent plats?
To produce a pea plant that only displays the recessive phenotype both of the parents must also have the recessive phenotype. In a four square, if one parent displays the recessive phenotype while the other has the dominant phenotype, one of every four offspring should theoretically receive the recessive phenotype as well, but if you want all offspring to be recessive, both parents must also be recessive.

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.
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.
Is Alzheimer's disease dominant or recessive?
it can be either if one parent has it and the other doesn't then it can be dominant. say both parents have it with them it depends on who has more likely chance to get it. did i help at all?
