Numerous barriers can prevent sperm from reaching and fertilizing the egg, this can be that the Sperm may be defected, or lack the required number of mitochondria needed to help move the sperm. Also, if sperm had already fertilized the egg, there is a change that takes place to the membrane surrounding the egg preventing further sperm from fertilizing.

cluponka [151]
<span>A scientific law describes repeated observations under a given set of conditions. These laws are not too specific, and they imply a casual relationship. These laws do not explain why something occurs, they merely state that something will occur if the given conditions are met. Therefore, the formation of a scientific law is a result of repeated observations. An example is Newton's first law of motion, which gives certain conditions for an object, such as no force acting on it, and then describes what the object will do in that situation, that is, remain in motion or remain stationary.</span>

Advocard [28]

The adaptive advantage of a fungus producing and secreting a bacterial inhibitor would be that it protects against microbial competitors: is an extensive surface area well suited for invasive growth and absorptive nutrition.

Fungus

A fungus is any eukaryotic organism that includes microbes like yeasts and moulds, as well as the more recognisable mushrooms. These organisms are classed as a kingdom distinct from the other eukaryotic kingdoms, which include Plantae, Animalia, Protozoa, and Chromista in one traditional taxonomy.

The presence of chitin in fungi's cell walls distinguishes them from plants, bacteria, and some protists. Fungi, like animals, are heterotrophs; they obtain nourishment by absorbing dissolved molecules, usually by secreting digestive enzymes into their surroundings.

Fungi, like plants, use chemical defence, which involves the creation of poisons that affect the growth, development, or viability of the antagonists.

how are genes expressed for a particular trait?

Genes are expressed in two ways which could be either genotype or phenotype

genotype reflects the dominancy or recessives of a particular trait over another while phenotype entails the physical expression of such trait which could be height, color of skin among others

e.g

If P is purple while p is white

PP x Pp= PP, Pp, PP. Pp these are the genotype produced from the crossing of two parents which results into 2 homozygous gene and 2 heterozygous gene without any recessive gene

while the phenotype shows that all the offspring are Purple
