    Frequency
In summary, the frequency of gametes can be calculated by dividing the number of a particular type of gamete by the total number of gametes in a population and converting it to a percentage. This is important for understanding the genetic makeup of a population and can be collected through observation or genetic testing. Factors such as natural selection, genetic drift, and environmental factors can affect the frequency of gametes, and it can also change over time due to these factors.

Homework Statement


2 parents, one has genotypes Cd/cD and the second has cd and CD
possible gametes and if r=.25 what are frequencies of gametes


Homework Equations


punnent square


The Attempt at a Solution


So the gametes came out to be Cc, CD, cd, dD and cC, cD, Cd, and dD but I am not sure how to get the frequency

This isn't about Punnett squares. Punnett squares are for predicting the genetic makeup of progeny, when given gametic frequency.

You are given a recombination frequency and are asked to find gametic frequencies. This is about homologous recombination.
 

1. How do you calculate the frequency of gametes?

The frequency of gametes can be calculated by dividing the number of a particular type of gamete by the total number of gametes in a population. This will give you a decimal value, which can be converted to a percentage by multiplying by 100.

2. What is the purpose of calculating the frequency of gametes?

Calculating the frequency of gametes is important in understanding the genetic makeup of a population. It can help determine the likelihood of certain traits being passed on to future generations and can also give insight into the potential for genetic disorders or diseases.

3. How do you collect data to find the frequency of gametes?

Data can be collected by observing and counting the number of different types of gametes in a population. This can be done through genetic testing or by analyzing the offspring of a population.

4. What factors can affect the frequency of gametes in a population?

The frequency of gametes in a population can be affected by several factors, including natural selection, genetic drift, and mutations. Additionally, environmental factors such as pollution or climate change can also impact the frequency of gametes.

5. Can the frequency of gametes change over time?

Yes, the frequency of gametes can change over time due to various factors such as natural selection, genetic drift, and mutations. For example, if a particular trait becomes more advantageous for survival, the frequency of gametes carrying that trait may increase in a population over time.
