Answer:
See the answer below
Explanation:
Normal height - H
Short height - h
Heterozygous - Hh
A cross involving heterozygotes would be Hh x Hh
Hh x Hh
HH Hh Hh hh
Since H is dominant over h;
HH and Hh would produce normal height phenotypes.
hh will produce a short height phenotype.
Thus;
<em>Probability of normal height phenotype resulting from the cross = 3/4 or 75%</em>
<em>Probability of short height phenotype resulting from the cross = 1/4 or 25%</em>
The image provided is not clear, however, the correct and clear image is attached with the answer:
Answer:
The correct answer is - 100 %
Explanation:
As we know DMD or Duchenne Muscular Dystrophy is a sex-linked recessive disorder and according to the given pedigree, it is clear that Individual I-1 is a normal male and 1-2 is a female who has two defective genes of the disorder as if she had only one defective gene she would have a carrier for the disorder.
All gametes produced by both male and female would be -
Male - X and Y
Female - Xd and Xd
Therefore all the male offsprings or son will get one defective gene Xh from the mother for sure and a Y chromosome from the father. All daughters will also carry one gene Xh that is defective from the mother and normal X from the father but would be carriers for the disorder.
Answer:
blood can still return via the deep veins
Explanation:
The venous system at the leg is known for its complexity and highly branched nature. The superficial and deep veins, both branches and connects with each other at different points along their length
Plate tectonics suggests that the lithosphere floats and moves on the asthenosphere.
so the other answer is incorrect.
