How did Mendel show that the green-seed trait did not disappear but was only masked?
Mendel demonstrated that the green-seed trait did not disappear but was simply masked by conducting crossbreeding experiments with pea plants. He observed that when he crossed purebred yellow-seed plants with purebred green-seed plants, the first generation (F1) exhibited only yellow seeds. However, when he allowed the F1 generation to self-pollinate, the second generation (F2) revealed a 3:1 ratio of yellow to green seeds, indicating that the green-seed trait was still present but hidden in the F1 generation. This suggested the concept of dominance, where the yellow trait masked the expression of the green trait.
Why is a dominat allele called dominant?
A dominant allele is called dominant because it can express its trait in the phenotype even when only one copy is present, overshadowing the effect of a recessive allele. This means that if an individual has at least one dominant allele for a particular gene, the dominant trait will be observed. The term reflects the allele's ability to "dominate" the phenotype in genetic expression.
Is green eye color a recessive trait?
Yes, green eye color is typically considered a rare trait that is usually inherited as a recessive genetic trait. Individuals with green eyes often have two copies of the recessive allele for eye color.
When Mendel bred green - pea plants and yellow - pea plants all the offspring had yellows means that?
When Mendel bred green pea plants with yellow pea plants and all the offspring were yellow, it indicated that the yellow trait is dominant over the green trait. This means that the yellow allele masks the expression of the green allele in the offspring. As a result, even though the green allele is present, it does not manifest in the phenotype of the plants. This observation was crucial in understanding the basic principles of inheritance.
What color leaves will you observe on the offspring of two green parent plant?
I think that you will have yellow becaues green color could make yellow.
In a hybrid individual the trait that is covered and not exspresed is called what?
dominat
Is speed a dominat trait?
Motion is a fundamental property of the universe, nothing is at absolute rest.
Is albinism a dominat or reccesive trait?
Albinism is a recessive trait which will result in a lack of pigmentation in the skin eyes and hair. It occurs about 1 in every 17,000 people in the U.S.
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.
If you have green eyes and both your parents have brown eyes what kind of trait does your parents have?
They both carried the gene for green eyes as a recessive trait.
What is the dominat religan in Burma?
Buddhist.
Are dimples dominat to no dimples?
Dimples are typically considered a dominant trait. This means that if one parent has dimples and the other does not, there is a higher likelihood that their offspring will inherit dimples. However, the expression of this trait can be influenced by multiple genes and environmental factors, making the inheritance pattern more complex than simple dominance might suggest.
Why do you have green eyes and your parents have brown?
Your parents carried the gene for green eyes as a recessive trait.
What is a sentence for dominant trait?
A dominate trait is a trait that appears even if an organism has only one factor for the trait.
What is it called when a ressesive and dominat gene mix?
When a recessive and dominant gene mix, the dominant gene will typically determine the trait expressed in the offspring. This is known as dominant inheritance, where the dominant gene masks the presence of the recessive gene in determining the phenotype.
Can a dog have green eyes?
Yes, some dogs can have green eyes due to a rare genetic trait.
What are dominat traits?
Dominant traits are genetic traits that are expressed over a recessive genetic trait. This relates only to single genes where one specific marker controls a genetic trait. Below is a fairly simple hypothetical explanation and (made up) example. Genetics is much more complex in reality and a full explanation can be found at the "Related Link" below the answer. Genes carry both a dominant marker and a recessive marker for a particular trait, one being donated by each original parent. One is dominant over the other and is expressed physically. For example, a person may have the trait for green eyes as well as for blue eyes, if the green is dominant, it is then physically expressed by the person having green eyes. The person still, however, carries the trait for blue eyes in his genetic makeup - which can still be passed on to his/ her offspring. In this instance his/ her offspring could either have blue or green eyes, depending on the traits inherited from the other parent. Bear in mind that when sex cells are produced by the parents, only one of the traits is donated by each parent. To extend the example from above, the parent could produce a gamete (egg or sperm) that has the trait for green eyes or others that have the trait for blue eyes. The cannot carry over the trait for say brown eyes, as that trait is not carried within their genetic make up (only green or blue). As mentioned above genetics is complicated; normally something like eye colour would be controlled by a number of genes and not just one, making the number of possible combinations more complex to calculate.
