The ALLELE is something that we are currently learning. HH, and hH are also something we are learning. The H is the dominant. To figure out what Geno is, go on Brainly! Genotypes are something you see in the cell. Changes. Phenotype is something tat you can see. Looks.
Sorry. This is all I can come up with. science magnet class, and we are learning very smart things, and we are currently learning about all of these things, and haven't gotten very far. Hope I helped!
The answer is (A) Mitochondria have their own DNA molecules, separate from the rest of the cell's DNA.
The endosymbiotic hypothesis concerns with the presence of two special organelles, mitochondria and chloroplast within the eukaryotic cell. These two organelles have their own set of DNA that is different from the nuclear DNA of the eukaryotic cell. It is believed that a primordial eukaryotic cell was in a symbiotic relationship with mitochondria-like bacterium. The primordial cell eventually engulfed the mitochondria-like bacterium for ATP production to power itself.
Answer:
45 chromosomes (2n1 + n2)
Explanation:
The allotetraploid 2n1+2n2=60 has 60 chromosomes total, two sets of them of type 1 and two sets of chromosomes from the other type (2).
If the suspected type 1 parent is diploid with 30 chromosomes, then the allotetraploid has 30 type 1 chromosomes and 30 type 2 chromosomes.
<u>During meiosis, the germ cells reduce the total chromosome number by half.</u>
- The gametes produced by the allotetraploid will have 15 type 1 chromosomes and 15 type 2 chromosomes.
- The gametes produced by the suspected parent will have 15 type 1 chromosomes.
When these gametes combine during the backcross, the F1 zygote will have a diploid number of 30 type 1 chromosomes (15 coming from the allotetraploid and 15 coming from the suspected parent) and 15 type 2 chromosomes (which will be haploid because they all came from the allotetraploid).
Answer:
The correct answer is option (e)-"All of the answer choices are correct".
Explanation:
Fossils are defined as the remains of ancient organisms. Fossils are obtained from impressions left after an organism decays. There are different kinds of fossils depending on the material they are made of and how they were formed. Some fossils are made from minerals that are the replacement of the organic matter of the ancient organism, or are the replacement of mud that came from footprints. Alternatively, fossils could be plant resins or tar that preserved a specimen within.
