Answer:
Explanation:
To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
The map unit is the distance between the pair of genes for which every 100 meiotic products, one of them results in a recombinant one.
So, en the exposed example:
- J and K are autosomal genes
- J and K are separated by 60 M.U.
- 60 M.U. means that there is 60% of recombination.
Cross) J K / j k x j k / j k
Gametes) JK Parental jk, jk, jk, jk
jk Parental
Jk Recombinant
jK Recombinant
One map unit equals 1% of recombination frequency. This means that every 100 meiotic products, one of them is a recombinant one.
1 M.U. -------------- 1% recombination
60 M.U. ------------ 60% recombination
30% Jk + 30% jK
100 M.U. - 60 M.U. = 40 M.U.
40M.U.--------------40 % Parental (Not recombinant)
20% JK + 20% jk
Punnet Square) JK jk Jk jK
jk JK/jk jk/jk Jk/jk jK/jk
J K / j k = 20%
j k / j k = 20%
J k / j k = 30%
j K / j k = 30%
Answer:
of diffusion
Explanation:
Molecules move down a concentration gradient without the need to use energy. This means they move from a high concentration to a low concentration. This occurs across a semi-permeable membrane, like the cell membrane, by simple diffusion.
Hi!!! I think the answer is B! Have a great rest of the day!!!
Alliances fall into two broad categories: contractual (non-equity) and equity-based.
projects, strategic suppliers, strategic distributors, and licensing/franchising (see Chapter 6 for
definitions). These are also limited in scope and duration.
Equity-based alliances call for a higher level of commitment. Examples include strategic
investment (one partner invests in another as a strategic investor) and cross shareholding (both
partners invest in each other). A joint venture is a special case of equity-based alliance that
establishes a new legally independent entity (in other words, a new firm which is the JV) whose
equity is provided by two (or more) alliance partners.
Although JVs are often used as examples of strategic alliances,
not
all strategic alliances are JVs.
Essentially, a JV is a “corporate child” given birth by two (or more) parent firms, such as
SonyEricsson’s set up by Sony and Ericsson. A non-JV, equity-based alliance can be regarded as
two firms “getting married,” but not having “children.” The Renault-Nissan alliance is such an
example.
Networks are also a form of strategic alliance. For the purposes of this chapter, we define
strategic networks as strategic alliances formed by multiple firms to compete against other such
<span>groups and against traditional single firms</span>
