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.

aev [14]

Answer:

neurocysticercosis

Explanation:

Cysticercosis is the infection caused by the cystic form of the pig's tapeworm, Taenia solium, and neurocysticercosis is when the central nervous system (CNS) is affected. It is usually possible through direct ingestion of helminth eggs, but it can also occur in a usual infestation (teniasis). It is an endemic condition in several countries in South America, Africa and Asia, accounting for about 29% of the causes of secondary epilepsy in these locations. It can also cause headache, hydrocephalus, meningitis, and even central nervous system infarction.

Igneous rock can ____ to form metamorphic rock A)melt B)harden C)heat up D)weather
alexandr402 [8]

Heat & Pressure ( So I guess in this answer choices it's " Heat up" )

The reason it's not " melt " because if melting were to take place then that would make Magma, and magma isn't metamorphic rock.
