Categorize allele interactions as completely dominant, incompletely dominant, or codominant.

Explanation:

Gregor Mendel showed his inheritance character in the garden pea plant. According to him, there are 2 alleles which are inheritable - dominant allele and recessive allele. The dominant allele is always dominant over the recessive one which is known as the complete dominance. When the offsprings have both recessive alleles it will show its character.

There are other characters present besides dominant and recessive. Such characters are known as Mendelian deviation as it does not obey Mendel's law of inheritance. e.g. codominance, incomplete dominance.

In codominance alleles, characters are blended and a new character has seen in the next generation. This new character is neither dominant not recessive, it is an intermediate character between the 2 characters.

e.g When the white and red flowers crossed pink flowers are formed along with red and white.

In the case of codominance, both alleles express their characters. Such phenotypic characters are known as codominance because both alleles are expressed in the offsprings.

e.g. When the red and white flower plants crossed the offspring flowers are red with white spots or the white with red spots.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
