If a homozygous dominant is crossed with a homozygous recessive for a given trait the offspring will be?

The phenotype will show the dominant trait. All dominant traits mask recessive ones; If the genotype is heterozygous (One dominant and one recessive) the organism's phenotype will be dominant.

∙ 11y agoThe offspring of a homozygous dominant and homozygous recessive cross will be heterozygous. This means that they will have one of each allele, and will have the phenotype of the dominant allele.
For example, if B leads to black fur and b leads to white fur:
The cross BB (black) X bb (white) will result in Bb (black) offspring.

What is an allele that expresses itself in a hybrid?
A hybrid is formed for example when a homozygous dominant (AA) individual is crossed with homozygous recessive (aa) individual. all the individuals which are produced in F1 generation are hybrids (Aa) in case of a hybrid only dominant allele is expressed, while the recessive allele remains suppressed due to dominant recessive relationship.
If a homozygous tall and short pea plant are crossed will the offspring be of medium height?
Not if either trait is dominant. Let us say tall is dominant ( I think it is ) and short is recessive. T = tall, and s = short. TT X ss will give heterozygous tall plants. Ts
When two cultives are crossed their offspring will be?
Their offspring will be heterozygous recessive.
Why were all the offsprins purple when gregor menel crossed true breeding purple flowered plants with true breeding white flowered plants?
All the offspring were purple because Mendel was dealing with simple genetic dominance. The purple true breeding parent was homozygous dominant and the true breeding white parent was homozygous recessive. When those two are crossed they create only heterozygous offspring (look up a punnett) and since this is simple dominance those heterozygous will show the phenotype of the dominant allele which is purple.
If a homozygous dominant parent and a heterozygous parent are crossed what percentage of the offspring are expected to be homozygous dominant?

A parent that is homozygous for a dominant trait is crossed with a parent that is homozygous for the recessive trait What percentage of the offspring will display the dominant trait?
100% of the offspring will display the dominant trait because the homozygous dominant parent can only pass on the dominant allele. The offspring will inherit one dominant allele from the dominant parent and one recessive allele from the recessive parent, resulting in a heterozygous genotype expressing the dominant trait.
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.
What would the offspring most likely be if an individual with a heterozygous trait and an individual with a homozgous recessive trait crossed be?
The offspring would have a 50% chance of being heterozygous and showing the dominant trait and a 50% chance of being homozygous for the recessive trait.
An individual heterozygous for a trait and an individual homozygous recessive for the trait are crossed and produce many offspring?
The offspring has a 50% chance of the dominate trait (while being heteroygous) and a 50% chance of having the recessive trait ( homozygous recessive).
What is the height of the f1 plant if the tall plant AABBCC is crossed with a base height plant aabbcc?
In such a cross, the F1 plants will always be tall, because that is the dominant allele. In the cross described, a homozygous dominant plant was crossed with a homozygous recessive plant; a cross that produces 100% heterozygous offspring. (AaBbCc)
In a testcross an organism with a dominant phenotype but unknown genotype is crossed with what to establish its genotype?
homozygous recessive
The F1 offspring of Mendel's classic pea cross always looked like opne of the two parental varieties because?
Because Mendel crossed two pure-breeding plants. One being homozygous dominant and one being homozygous recessive. All of the progeny ended up being heterozygous, causing them to take on the dominant phenotype and look like the homozygous dominant parent.
Individual heterozygous for a trait and an individual homozygous recessive for the trait are crossed and produce many offspring?
of two different phenotypes
What is the difference fom heterozygous and homozygous recessive?
In genetics, you can either have a dominant allele (A) or a recessive allele (a). Being homozygous means that you have both of either a dominant or a recessive allele (ie you are either AA or aa). If the trait is a recessive trait, then you need to have it be homozygous recessive in order to express that trait. Hope this was helpful! :-)
If homozygous BB is crossed with homozygous bb what will the offspring have?
The offspring will get the qualities , traits of homozygous BB.
If a homozygous dominant plant crossed with a homozygous recessive plant what is the genotype and phenotype of their offspring?
If two homozygous plants with contrasting traits are crossed, the expected genotypes for the offspring will be heterozygous. The dominant trait would be expressed, but they'd be carriers for the recessive trait.
If homozygous BB is crossed with homozygous bb what will the offspring have-?
The offspring will get the traits of Homozygous BB .
