When cells become unable to regulate the cell cycle, tumors can develop.
Answer:
A. If neither parent expresses the trait, but the offspring does, both parents must be heterozygous for the trait.
Explanation:
If neither parents express the trait is because they are heterozygous and the dominant allele is being expressed over the recessive trait. When parents cross they have 25% of having an offspring that expresses the recessive trait, this means the offspring is a recessive homozygous. In the attached example 25% or 1/4 will have a short stem.
If it is a healthy environment then the atmosphere will be happy meaning no dirty streets etc
Answer:
It is a biological process by which an organism reproduces an offspring who is biologically similar to the organism.
Explanation:
I hope I have cleared ur doubt if not do mention in comment
Answer:
Describing a trait as dominant does not mean it is the most common; it means that it is expressed over the recessive trait. For example, tongue rolling is a dominant trait, controlled by the dominant version of a particular gene (R). Individuals with one or two copies of R will exhibit tongue rolling.
