Answer:
Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive. Recessive traits are found in fewer individuals as it can only be expressed in hom.ozygous condition. In a monohybrid cross between heterozygotes there is only 25% chance of recessive trait being expressed and 75% chance of dominant trait being expressed. Therefore in a population dominant trait is more apparent.

Explanation:
Phylum Cnidaria; Cnidarians are diploblastic with two embryonic germ layers -the ectoderm and the endoderm) with well structured tissue, performs extracellular digestion, and use cnidocytes for defence and to catch prey.
Cnidarians have two unique morphological body plans which are referred to as polyp, its sessile in adults, and medusa are mobile; some species has both body structures in their lifecycle.
It undergo extracellular digestion, where enzymes dissolve the food substances as its cells lining the gastrovascular cavity take in the nutrients.
Cnidarians are known to have a body arrangement of incomplete digestive system with just one opening; the gastrovascular cavity that functions as both a mouth and an anus.
The cnidarians undergo extracellular digestion, the food is moved to the gastrovascular cavity, enzymes are present in the cavity, with the cells lining the cavity taken in nutrients. The gastrovascular cavity possess a singular opening that acts as a mouth and an anus; this is referred to as an incomplete digestive system.
Explanation:
so X-linked agammaglobulinemia (XLA) is a rare genetic disorder discovered in 1952 that affects the body's ability to fight infection. As the form of agammaglobulinemia that is X-linked, it is much more common in males.
