The reason for the offspring to present these genotypes is that during the formation of the gametes, the alleles separate and are inherited independently, therefore they can generate several different phenotypic combinations.

Explanation:

In order for an offspring to present very different phenotypes, as shown in the question above, it is necessary that the two red griffins with blue eyes that were crossed are heterozygous. Thus it will be possible for the offspring to present a wide variety of phenotype, according to Mendel's second law.

Mendel's second law is called the Law of segregation. This law explains that the alleles (which determine the characteristics of individuals) are separated in the formation of gametes and inherited by the offspring of a cross independently, and can generate different combinations of phenotypes, when the parents of a cross are heterozygous.

PLEASE HELP! WILL GIVE BRAINLIEST AND POINTS!

natulia [17]

Answer:

A. Lancelet

B. All chordates

Explanation:

A. Dorsal nerve chord is the only unique feature among all members of phylum chordata (mainly found in subphylum Vertebrata). In the given list, only lacelet is the Chordate whereas snail belongs to phylum Mollusca, grasshopper belongs to Arthropda, and jellyfish belongs to Cnidaria. Dorsal nerve cord runs along the length of organism's body.

B. Gill slits are opening structures to gills through which water passes from pharynx/throat to exterior. Their main purpose is to help filter the food particles available in surrounding water. Although they are typical for amphibians and fishes, chordates also possess gill slits at embryonic stages.
