Answer: There is a 50% chance that the offspring will inherit Huntington's disease
Explanation:
Huntington's disease is expressed by a dominant allele.
Since the father is heterozygous for Huntington's disease, his genotype would be as follows:Hh
Even though he carries a normal allele, the dominant allele is disease causing and thus masks the effects of the normal allele, therefore he expresses the disease.
The mother does not have Huntington's because she is homozygous recessive, in other words, she carries 2 copies of the normal alleles.with the genotype hh.
If you do a punnet square, and you cross the mother and father, the following genotypes can be produced:
Hh, Hh, hh, hh
Therefore, there's a 50% chance that the offspring will inherit the disease causing allele and 50% chance that the offspring will not inherit it.
Answer: dna and rna have four nitrogenous three of which they share Cytosine, Adenine, and Guanine the differs between the rna has Uracil and the dna has thymine but dna is doubled stranded and rna is single stranded
Thymine
Explanation:
Answer:
O N C H
Explanation:
Oxygen has more valence electrons present in its outermost shell which is why it is the most electrovalent.
Nitrogen follows suit too while the remaining aren’t electronegative but electropositive
Answer and Explanation: In anatomy, bodies are divided by hypothetical geometric planes to describe location or direction of its structures. These planes are called Planes There are 3 reference planes:
1) Sagittal Plane divides the body into sinister and dexter (left and right) sides.
2) Coronal Plane divides into anterior and posterior portions.
3) Transverse Plane divides into superior and inferior portions.
For the anatomist, to have a section that shows the entire medial surface, should be ordered the <em><u>Sagittal</u></em> <em><u>Plane</u></em>, more especifically <u>midsagittal (median) plane</u>.
