When an offspring receives a dominant gene from one parent and recessive gene from another parent what type of trade shows up in the offspring?
When an offspring inherits a dominant gene from one parent and a recessive gene from the other, the dominant trait will typically be expressed in the offspring. This occurs because dominant alleles mask the effects of recessive alleles. For example, if the dominant gene is for brown eyes (B) and the recessive gene is for blue eyes (b), the offspring will have brown eyes (Bb) as the dominant trait prevails.

Does a recessive allele need another recessive allele to be expressed?
Yes, a recessive allele needs to be paired with another recessive allele in order to be expressed. This is because recessive alleles are only expressed when an individual has two copies of the recessive allele, one from each parent. If an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele will be expressed.
Which matings would produce the phenotype ratio of 93331?
To achieve a phenotype ratio of 9:3:3:1 in offspring, you would need to perform a dihybrid cross between two heterozygous individuals (AaBb x AaBb) for two traits that assort independently. Each trait should have two alleles, with dominant alleles producing the dominant phenotypes. This cross results in the classic Mendelian ratio where 9 offspring display both dominant traits, 3 show the dominant trait for the first and recessive for the second, another 3 show recessive for the first and dominant for the second, and 1 exhibits both recessive traits.
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
Another plant is said to be heterozygous for flower color what does this mean?
homozygous means that the alleles that make up the genotype are the same, for example homozygous dominant would have two dominant alleles (RR) or homozygous recessive would have two recessive alleles (rr). the alternative would be heterozygous, where the genotype contains both a dominant and a recessive allele (Rr). so a homozygous plant would either have two dominant alleles or two recessive alleles for the seed colour. Now the way to find out whether it is homozygous dominant or homozygous recessive is to do a cross with a homozygous recessive plant and look at the seed colour (the phenotype). if the the original genotype is homozygous dominant the offspring seed colour will show the dominant seed colour becasue it will be heterozygous. But if the original plant is homozygous recessive the offspring will show the recessive phenotype.
A gene is recessive when?
Most genes have two copies of each gene with dominant gene "trumping" the recessive one. The gene is recessive because it is said not to do much of anything unless paired with another recessive gene, but if paired with a dominant gene, the dominant gene wins.
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.
In which offspring does a dominant trait appear?
A dominant trait will appear in offspring that inherits at least one copy of the dominant allele from either parent. If an individual has two different alleles for a trait (one dominant and one recessive), the dominant trait will be expressed.
If one parent has two dominant alleles and another parent has two recessive alleles the offspring will have?
One copy of each allele, resulting in the offspring having one dominant allele and one recessive allele. This combination is known as heterozygous.
If one parent has two dominant alleles and another parent has two recessive alleles the offspring will be what?
yes I don't know
How are two traits that have Dominant and Recessive alleles inherited?
The trait received is recessive.
Can full sized dogs have miniature offspring?
yes because if it is heterozygous dog that means that it has a dominant gene ( big ) and a recessive gene ( small ) and that means the dog is Tt capital t is dominant and if they breed with another homozygous recessive dog that means that out of every 4 puppies 2 will be big and 2 will be small ( p.s homozygous means that you have all dominant or recessive genes )
Are dominant traits more likely to be inheritd then recessive traits?
Yes. When looking at Gregor Mendel's laws of inheritance, the Dominant allele will always be inherited by the offspring, as it is more potent than the 'weaker' recessive allele (unless the recessive allele is present in both parents; this can be in the form of Aa or aa, but it must be present in both for the recessive allele to be present in the offspring). There are other cases, though, such as co-dominance, in which recessive alleles are more likely to be present in the offspring, but speaking in general terms, it is the Dominant (ex. AA / Aa) alleles that show up more commonly in offspring than the recessive (ex. aa) alleles.
Does a recessive allele need another recessive allele to be expressed?
Yes, a recessive allele needs to be paired with another recessive allele in order to be expressed. This is because recessive alleles are only expressed when an individual has two copies of the recessive allele, one from each parent. If an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele will be expressed.
In order for a child to inherit a recessive trait both parents must be carriers of the recessive gene?
No. A recessive gene can be inherited from one parent, a dominant from another, or two alike dominants. (No such thing as two alike recessive, the gene with the furthest back dominant gene. Say a blonde little girl has a blonde hybrid mother and a brown hybrid father. She ended up getting brown recessive. Since both of her parents were hybrid, she only had a recessive hair color gene from one parent.
Why are some parents traits expressed in their offspring and others are not?
Some traits are recessive and some are dominant. The recessive trait could be masked/hidden because of the dominant trait. Two copies of recessive alleles are needed to be shown in the phenotype.
When can a recessive gene assert itself?
When a parent for example has one dominant and onee recessive e.g Fe and another parent is a carrier for it e.g ee this will make the gene produce a trait of the offspring having a 50% chance of being a carrier
Trait of an organism that can be masked by the dominant by the dominant form of a trait?
A recessive trait is a characteristic of an organism that can be masked by the dominant form of a trait. It is only expressed when an individual inherits two copies of the recessive allele. Examples include blue eye color being masked by brown eye color.
