Marfan syndrome is a dominant trait. A cross between a homozygous dominant and a heterozygote would produce what phenotypic rati
umka2103 [35]

Answer:

The correct answer is- 4:0

Explanation:

Marfan syndrome is a genetic problem which affects the connective tissue in the body. The trait for this disease is autosomal dominant which means even one abnormal copy of this gene in the offspring or individual is sufficient to cause this syndrome.

Let S is the allele that is dominant for this syndrome and s is recessive. So if a cross between homozygous dominant(SS) and heterozygous individual (Ss) occurs than all the offspring would have this syndrome.  

                                   S      s

                              S  SS   Ss

                              S  SS   Ss

Therefore all 4 offspring would have at least one dominant allele which is sufficient to cause this syndrome. So the phenotype ratio would be 4:0.

Exercise
Goryan [66]

I just took the test this would be the correct answer.  

 

In the Precipitation Map of Washington, the dark orange section indicates low rainfall in the region. Using the Shaded Relief Map of Washington, you can tell that this area is flat, possibly a plain. These regions typically don't receive a lot of rain. The Precipitation Map of Washington has areas that are dark purple and dark green. This indicates that they both receive a lot of rainfall every year. If you look at these areas on the Shaded Relief Map of Washington, you can tell that these areas with a lot of rainfall are mountainous.  

On the Precipitation Map of Washington, purple/blue means more rain, and orange/red means less rain. The Shaded Relief Map of Washington shows mountains (brown), valleys, plateaus, and canyons. Areas that are flat are smooth on the map. Areas with steep slopes and mountains look rougher.

Explanation: This was on my feedback from the test as possible answers.
