Do either of your diseases in part A have the same pattern of inheritance as the model colorblindness mutation you made?How do y
Alborosie

Answer:

Autosomal dominant pattern.

Explanation:

If the pattern of inheritance is same in the disease just like the model of colorblindness mutation so we can say that the disease has autosomal dominant pattern because the colorblindness mutation also occur due to the autosomal dominant pattern. Sometimes the disease is also inherited from their parents through genetically. So both diseases and the model colorblindness mutation are considered same if both have the same pattern of inheritance.

Explain the relationship between genotype and phenotype. How can one phenotype result from more than one genotype?
koban [17]

Answer:

<h2>Genotype is the set of genes( allele) of an organism. </h2><h2>Phenotype is the physical expression of the genetic composition of an organism. </h2>

Explanation:

Genotype: 1. It is the genetic composition of an organism, means it is the set of genes( allels) of an organism's DNA, which is responsible for a particular trait of an organism.  

2. Genotypically, an organism can be homozygous(dominant or recessive) or heterozygous.  Some Alleles are dominant over other, means some can  be dominant or other can be recessive.  

3. Genes are responsible for all the traits in an organism, and these traits are inheritable. All the offsprings inherit all traits from their parents.  

Phenotype: 1. Physical expression of the genetic composition of an organism resulted as  phenotype.

2. It  is the physical expression of genes (alleles) which are responsible for any trait.

Fossil evidence indicates that the first organisms on Earth were single-called prokaryotes. The first eukaryotes are believed to
icang [17]

The study of fossils shows that the eukaryotic cells have been evolved from the prokaryotic cells. The endosymbiotic theory has been used to study the evolution of eukaryotic cells.

The endosymbiotic theory states that:

  • Endosymbiotic theory is also referred to as the theory of symbiogenesis. The theory explains the evolution of eukaryotic cells from prokaryotic cells.

  • The theory explains the presence of chloroplasts and mitochondria, and how these organelles form the eukaryotic cells. The theory explains the origin of mitochondria in animal cells and chloroplasts in plant cells.

Thus, the endosymbiotic theory defines the development of eukaryotic cells from the prokaryotic cells.

To know more about endosymbiotic theory, refer to the following link:
