The information in pedigrees that is useful for mapping disease genes is sometimes limited. This pedigree shows segregation of n

eurofibromatosis, which is a fully-penetrant, autosomal dominant condition, and a single nucleotide polymorphism, SNP1, which has alleles G or T. Why is the cross in generation I not useful for determining the degree of linkage between the disease-causing gene NF and SNP1?

Answer:

Since neurofibromatosis is an autosomal dominant condition, the cross between individuals with genotypes carrying the same SNP type is not useful to show the degree of linkage between the disease-causing gene NF and SNP1. This occurs because it is necessary to observe segregation for the trait in order to determine its effects

Why are Chromosomes defined as rganisms
Xelga [282]

A chromosome is a DNA (deoxyribonucleic acid) molecule with part or all of the genetic material (genome) of an organism. Essentially, chromosomes are the basic building block of who we, as humans, are. They make up or DNA structure and are responsible for if we have blue eyes or black hair, without chromosomes, us as humans wouldn't exist. We, as humans, are the organisms that chromosomes make.

jonny [76]

Answer:

1. Archaeplastida.

2. Excavata.

3. Amoebozaons.

4. Stramenopiles.

5. Rhizarians.

6. Alveolates.

Explanation:

Protists can be defined as any group of eukaryotic organisms that belongs to the kingdom protista and are not plant, animal or fungus.

These are the six (6) groups of protists;

A. <u>Archaeplastida</u>: have a cell wall and both an outer and an inner membrane. There are no membraneous organelles in this group.

B. <u>Excavata</u>: have a feeding groove on one side and are usually single-celled. Members include organisms with heterotrophic, photosynthetic, parasitic, or symbiotic lifestyles.

C. <u>Amoebozaons</u>: use pseudopodia to move and may be either single-celled or multicellular. Members within this group exhibit free-living and parasitic lifestyles.

D. <u>Stramenopiles</u>: have a tinsel flagellum and are photosynthetic.

E. <u>Rhizarians</u>: have elaborate tests composed of calcium carbonate, silicon, or strontium salts. Members have thin pseudopodia that project from the test.

F. <u>Alveolates</u>: have membrane-enclosed sacs beneath the plasma membrane. There are photosynthetic and heterotrophic members in this group.
