Talja [164]3 years ago
5 0

English:

In parthenogenetic reproduction, the egg cell develops into a new or ganism without fertilization. It is clear that the most essential feature of parthenogenesis, absence of fertilization, causes important alterations of basic nature in cytological, as well as in genetic, respects.

Ukrainian:

При партеногенетичному розмноженні яйцеклітина перетворюється в нову або ганізм без запліднення. Зрозуміло, що найважливіша особливість партеногенезу, відсутність запліднення, викликає важливі зміни базового характеру як в цитологічному, так і в генетичному відношенні.

Cystic Fibrosis is a homzygous recessive disease that affects 1 in 3400 people. What percent of the population are carriers?
Vinil7 [7]

Answer:

The correct answer is = 0.02 or 2.5 percent approx.

Explanation:

Given:

CF is a recessive disease that affects 1 in 3400 people

The frequency of the recessive allele in the population (q2) -

= 1/3400

= 0.0002. Therefore, q is the square root, or 0.014.

The frequency of the dominant allele in the population (p)

= 1 - 0.014 = 0.986 (or 98.6%).

The percentage of s carriers in the population.

2pq equals the frequency of heterozygotes or carriers, then the equation will be as follows:

2pq = (2)(.986)(.014) = 0.02 or 2.5 percent approx.

Why does temperature stay the same during a phase change?
Bumek [7]
Changing the amount of heat energy usually causes a temperature change. However, during the phase change, the temperature stays the same even though the heat energy changes. This energy is directed into changing the phase and not into raising the temperature. That's why the temperature of water doesn't increase as it is boiling.
