Ralph's wants to breed two of his prize bulldogs. For the dominant alleles, he has selected small ears (E) and a curly tail (T). Linus, the male bullbog, is homozygous dominant for both traits. Lucy, the female, is heterozygous dominant for both traits. A. What are Linus's and Lucy's genotypes?
B. What percent of their pups will have small ears and curly tails?
C. What percent will have large ears (e) and straight tails (t)?

Answers

Answer:

a) Linus's  genotypes - EETT

Lucy's genotypes- EeTt

b) 100 percent of their pups will have small ears and curly tails

c) 0 percent of their pups will have large ears (e) and straight tails (t)
Okay, so we have one homozygous, the prefix "homo" means "same" and we know that the male's genotype is dominate, so with the prefix "same" or "homo" we know the male's genotype must be EE, and TT. We also know that the female's genotype is heterozygous, and knowing that "hetero" means opposite, we know that she has the two opposite types of genes Ee and Tt

A) ecosystem
B) community
C) population
D) biome

Answers

The level of organization is the arrangement of the organism from the simplest to the most complex level. Biome level of organization is not seen in Everglades. Thus, option D is correct.

What is the level of organization?

The organizational level depicts the arrangement of the organism from the most simple chemicals to the most complex biome and biosphere. The chemicals and atoms aggregate to form cells and tissues. The tissues performing similar activities make the organ.

The various organs combine to form the organ system that in turn makes the organism. This organism makes the population. Various population of the species makes the community and ecosystem.

The various ecosystems combinedly make the biome followed by the biosphere. Everglades is not a biome as it involves various ecosystem that interacts together.

Therefore, option D. Everglades does not show biome.
