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.
Answer:
I feel it's to easily differentiate the positive from the negative...... like in gram staining of bacteria, the colour tell us which bacteria is gram positive or gram negative...... I just feel that this is science and it is advisable to know what the opposite result of an experiment should look like.
• The kingdom PROTISTA includes autotrophic and heterotrophic, unicellular and multicellular organisms.
• The most specific taxonomic level is SPECIES
• The characteristic of all living things is PRODUCE OFFSPRING BY MEANS OF SEXUAL REPRODUCTION
• In 1990 —> SOME ORGANISMS WHICH WERE PREVIOUSLY CHARACTERIZED TOGETHER WERE DETERMINED TO BE GENETICALLY VERY DIFFERENT
• a virus is not living because it does not have —> GENETIC MATERIAL
• An amoeba, oak tree, squirrel, and mildew are classified in the same —> DOMAIN
* for the rest of the questions, im assuming there’s a picture, could you provide one?*
That will allow materials into via a passive transport Mechanism and as water and solute movement
