Question

A population of wild poppies endemic to the California Channel Islands occurs in two discreet varieties an erect from and a low ground hugging from. The morphology of growth is governed by a single somatic gene erect is dominant and is recessive. In 2005 population geneticist studied poppies on remote and windy San Miguel island and found the low from to be the most common variety -925 of the plants identified and studied. What was the allele frequency for the dominant allele in the 2005 poppy study? Assuming the population was in Hardy-Weinberg equilibrium, how many individuals in the 2005 Population would have been heterozygote's? What was the dominant allele frequency in the 2015 poppy population? Another group of scientist studied the introduced bees. They discovered the bees had become major vectors for the pollination of' plants on the islands. Moreover, they found the bees were much more likely to visit the flowers of upright and erect plants than those of low-lying ground hugging plants Applying this observation to the island poppies, which two assumptions for a Hardy-Weinberg population were being violated? Simple X-linked red-green color blindness affects 10% of the males but only 0.49% of the females in the U.S. population of 330 million Assuming an even sex ratio for males to females, how many copies of the recessive allele responsible for red-green color blindness are present in the U.S.? |Show your work. | Red-green color blind Tony has a normal appearing daughter. Tina. Tina meets, marries and mates with red-green color blind Tommy. What is the probability that Tina and Tommy can produce a son with normal vision? (Show you. well, you know.)

Explanation / Answer

Answer:

65). A female produced from color blind father would be carrier for color blindness.

Normal chromosomes= XC (X-chrosomesome; C=normal allele)

Color blind = Xc

Tina(XCXc) x Tommy (XcY)

Xc

Y

XC

XCXc (normal daughter)

XCY (normal son)

Xc

XcXc (color blind daughter)

XcY (color blind son)

If we considered only sons, 50% of the sons are normal and the remaining 50% of the sons are color blind.
