You cross two red griffins with blue eyes and produce offspring that are: red with blue eyes, red with green eyes, white with bl
sergejj [24]

Answer:

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.

Angiosperms, dicots

Explanation:

Angiosperms are highly differentiated vascular plants which can produce flowers and bear fruits with seeds in them. These flowering plants undergo reproduction and produces new plants. The reproductive parts like ovules and ovaries, stigma, stamen, pollen are all present in the flowers.

Angiosperms can either be a monocot or dicot. If they contain two embryonic leaves or cotyledons they are referred as dicots. Flowering angiosperms like geranium, magnolias are all dicots.

Geranium is a dicot angiosperms that produces small purple flowers.

Gymnosperms or bryophytes do not bear flowers or fruits. Monocots have only embryonic leaf.
