The probability that the child will not inherit Huntington’s disease is therefore 1/4.
<h3>What is Probability?</h3>
This is defined as a numerical description of how an event is likely to occur and the formula is :
Number of favourable outcomes/Total Number of outcomes.
When the heterozygous traits(Hh × Hh) are crossed, we have HH, Hh, Hh, hh.
The recessive trait is hh which makes the probability to be 1/4 in which the resulting child will not inherit the disease.

<u>Answer</u>: A) They have been geographically isolated from each other for a longer time.
<u>Explanation</u>: An isthmus is defined as a narrow strip of land that separates two bodies of water as well as connecting two larger landmasses at the same time. Thus, an isthmus if an efficient physical barrier that has separated an original shrimp species. This has resulted in the extant deep-water shrimp species through the evolutionary process known as allopatric speciation.
The age of an isthmus is in the range of at least two million years. Thus, the two deep-water shrimp species have been separated from each other for a very long time.
Answer: The passing on of traits and physical features from parents to children.

Answer:
77 miles.
Explanation:
28 miles per hour.
to break it up.
1 mile = 28

3/4 of 28 is 21.
21 + 56 = 77
