The pedigree shows the inheritance of an autosomal recessive disorder. What is the genotype of Steve and Sonya's son?
FromTheMoon [43]

Answer:

The answer is pp

Explanation:

Steve and Sonya's son genotype is pp. Because an inheritance of autosomal recessive disorder  is with recessive allele responsible for the exceptional phenotype. In this case, Steve and Sonya are both heterozygotes, Pp, which means they both have a p allele  because each one gave the boy a p, contributing to affect his son. And since we are talking about inheritance of an autosomal disorder, we know that the parents phenotypic proportions are the same.

Please rewrite in own words. PLEASE HELP VERY DESPERATE!!!!!!!!!!!!!!!

Fossils give  Scientists look into past life. A dinosaur that mixes together a reptile and a bird  helps scientists understand present day reptiles & birds. Animal Ancestry helps Scientists discover what ancestors of present day animals are. example: a dinosaur and an alligator.  DNA sequences help with this. By matching together the strands of DNA from these fossils can help scientists match together the strands of DNA sequences  For example the gene for a protein found in a horse will overlap in sequence fairly well with the protein gene from a cow but will not match very well with a worm.

Set of answers are:

A) protein subunits associated with gap junctions. <u>Conexin</u>

B) a type of adhesive junction connecting an epithelial cell to the basal lamina.<u> Hemidesmosome</u>

C) collection of fibrous intracellular attachment proteins.<u> Plaque</u>

D) create a permeability barrier. T<u>ight junctions</u>

E) button-like points of strong adhesion between two cells. D<u>esmosome</u>

F) hollow cylinders associated with gap junctions. <u>Connexons</u>

G) type of adherens junction connecting cells with the extracellular matrix. <u>focal adhesion</u>

H) intermediate filaments associated with plaques. <u>Tonofilaments</u>

I) collection of adherens junctions particularly associated with epithelial cells.

J) type of adhesive junction containing actin microfilaments. <u>Adherens junctions</u>

K) specialized modifications of the cell membrane in which two cells come together in multicellular organisms. C<u>ell junctions</u>

L) point of cytoplasmic contact between two cells. <u>Gap junction</u>

M) anchors cytoskeleton of one cell with that of a neighboring cell. <u>Adhesive junction</u>

<u />

Explanation:

<u>Connexin:</u> is a transmembrane protein that forms the gap junctions, they are also called gap junctions proteins.

<u>Hemidesmosome junctions:</u> these types of junctions are in the epidermis, specifically between the epithelial cells and the basal lamina of the epidermis.

<u>Plaque:</u> they are part of the adherens junctions, they are fibrous proteins that are attached to certain points of the extracellular matrix.

<u>Tight junctions</u><u>:</u> are junctions between two epithelia, they are very restrictive and do not allow the passage of soluble molecules creating a permeability barrier.

<u>Desmosomes</u>: are very strong cell to cell junctions on the lateral sides of plasma membranes. They are in tissues that are under mechanical stress, such as the cardiac muscle.

<u> Connexons:</u> is a pore made of six connexin proteins in a gap junction. Connexons are the ones that connect two cells in gap junctions.

<u>Focal adhesions:</u> They connect the extracellular matrix with the cell, regulatory signs and mechanical force is transmitted through them.

<u>Tonofilaments:</u> tonofilaments are the ones that are associated with a plaque in adherens junctions, they are in epithelial tissues.

<u>Adherens junctions:</u> are cell to cell junctions where the cytoplasmatic face is connected to the actin cytoskeleton. They appear as spots forming the plaque or as zonula adherens, which are actin bands around the cell.

<u>Cell junctions </u>are protein complexes that connect two cells that are next to each other or a cell with the extracellular matrix. They have a lot of functions, such as pas information from cell to cell, or the exterior, form a barrier, synchronize cells, etc.

<u>Gap junctions:</u> are connections between the cytoplasm of two cells, molecules and, ions pass directly from one cell to the other.
