Seeds come in different sizes and shapes. Some are oval with a point at one end. This would be an example of an apple seed. Other seeds are helicopters which means they spin when dropped. An example of this seed is a conifer tree seed.

What has two identical alleles for a trait?
A heterozygote is an organism with two different alleles for a trait.
What is the purpose of a ovule in a flower?
name the two bean shape structures
When two or more forms of the gene for a single trait exist some forms may be?
dominant and others may be recessive.
Can several alleles affect a single trait?
When there are multiple alleles present for a trait a variety of phenotypical outcomes is possible. These traits can be dominant, recessive, co-dominant, or incompletely dominant.
What is it called when two forms of a trait are both are dominant at same time?
Codominance. It's the case of AB blood types, for instance. Neither trait is dominant over the other, so both manifest.
What are two forms of the trait of seed shape in pea plants?
Mendel described two seed shapes among the pea seeds in his study: Smooth and Wrinkled.
What is heterozygouz?
Many organisms contain two copies of each chromosome, and generally these two chromosomes are not identical. If a particular trait, such as the shape of a pea, is determined by one particular section of a chromosome, it is possible for the two copies of the chromosome to have different instructions for the trait. If the two sections of the two chromosomes have different instructions, this is called being heterozygous.Often if an organism is heterozygous for a trait, one of the sets of instructions (called an allele) will be dominant over the other. This means that if either of the chromosomes has that dominant version of the allele, that is the set of instructions that will be followed.Examples: The gene for seed shape in pea plants exists in two forms, one form or allele for round seed shape (R) and the other for wrinkled seed shape (r). A heterozygous plant would contain the following alleles for seed shape: (Rr).Organisms have two alleles for each trait. When the alleles of a pair are heterozygous, one is dominant and the other is recessive. Using the previous example, round seed shape (R) is dominant and wrinkled seed shape (r) is recessive. Round: (RR) or (Rr), Wrinkled: (rr).
What two forms of traits for seed shape did Mendel Observe?
Mendel observed round and oval seed shapes.
What are two forms of traits of seed shape in pea plants?
Mendel described two seed shapes among the pea seeds in his study: Smooth and Wrinkled.
What has two identical alleles for a trait?
A heterozygote is an organism with two different alleles for a trait.
What is a contrasting trait?
pea has many sharply ditinct traits each trait has two clear alternative forms e.gseed shap has round or wrinkled phenotype plant hieght was long or short seed colour was yellow or green Mendel called them pair of contrasting trait
What does it mean if there are 2 different alleles for a trait?
A Trait Could Show Up In Two Different Forms
What happens when a trait shows codominant alleles?
two forms of the trait are both equally dominant apex
What is the purpose of a ovule in a flower?
name the two bean shape structures
Organisms with two different alleles for a trait?
The organism that has two different alleles for the same trait is called heterozygous. This also refers to a cell or an individual that has two different forms of gene.
When two or more forms of the gene for a single trait exist some forms may be?
dominant and others may be recessive.
What two forms of matter have no shape of their own?
Liquids and gases have no shape of their own.
