Answer:
cloning, Finn-Dorset, DNA, nucleus
Explanation:
So basically what they're doing here is they're taking the cytoplasm of a cell of the Scottish Blackface sheep (maybe a lamb?, whatever)/removing the nucleus inside that cell and instead inserting the nucleus of the Finn-Dorset sheep. Then they insert that "integrated" cell (so to speak) into a surrogate ewe so that the blastocyst can evolve and develop into Dolly (the lamb/sheep).
The process is cloning. The resulting offspring would be genetically identical to the Finn-Dorset (sheep/lamb) b/c the nucleus is coming from that sheep & the nucleus has the genetic material (DNA). Hope ya found this helpful :)
P.S. Oh yeah, and thanks for the fifty points (hopefully)
Geophysicists are Earth scientists. Hope this helps!
Answer:
There is no punnet square attached but generally none of the offsprings from this cross will be homozygous dominant. The answer is 0.
Explanation:
The question illustrates a single trait encoded by a single gene. According to Mendel, a gene comes in two alternative forms called ALLELES. Each allele encodes different characters of the same gene. For example, let's use the trait for height encoded by a certain gene that has alleles T for tallness and t for shortness. T is dominant over t, meaning that T (tallness) will always mask the phenotypic expression of t (shortness) in a heterozygous state.
A heterozygous parent contains different alleles of the same gene i.e. Tt in this case. However, due to the dominance of allele T (tallness) over allele t (shortness), the tall trait will be expressed. On the other hand, a homozygous recessive parent contains the same alleles for the recessive trait i.e. tt
Using a punnet square, a cross between a heterozygous (Tt) parent and a homozygous recessive parent (tt) will produce offsprings with genotypes: Tt and tt in a 1:1 proportion.
Tt is heterozygous dominant
tt is homozygous recessive
None of the offsprings are homozygous dominant (TT), hence, the probability of producing a homozygous dominant offspring is 0.
t t
T Tt Tt
t tt tt
Answer:
Actually, the remains of a Hadrosaur are an example of a body fossil, or fossils of the actual organism. Typically, hard structures like bones, shells, and teeth fossilize more often than soft-bodied structures like tissues or plant leaves, but as is seen with the horsetail relative, plants can become fossils.
Explanation:
Answer:
Unicellular. Bacteria are single-cell organisms. Bacteria are microscopic, usually 0.5 to 5 microns in length, and are generally smaller than eukaryotic cells. Unlike a human muscle cell or blood cell, a bacterial cell is a self-sufficient living being.
