5.A man with type AB blood is married to a woman with type Oblood. They have two natural children, and one adopted child. Thechildren's blood types are: A, B, and O. Which child was adopted?Give reason for your answer. Show your work. (Show a Punnett squarethat proves your answer.)
This case involves the ABO blood group. We know that the A and B alleles are co-dominant, and both are dominant to the O allele. What would be the potential genotypes and phenotypes of the children if the mother has Type O blood and the father has Type AB blood? Show your work using a Punnett square.
A couple is planning to have a child. The man is homozygousrecessive for Marfan syndrome, a dominant disorder. The woman isalso homozygous recessive for the disease. What is the chance thattheir first child will inherit the disease?
Let's assume that you can roll your tongue (a dominant trait).Use R to denote the dominant allele and r to denote the recessiveallele. Which of the following could NOT be your genotype? Group ofanswer choices rr this cannot be determined from the informationprovided Rr RR
Arrange the structures in order from smallest to largest (molecules, organelles, atoms, organs, organisms, cells, tissues, and organ systems).
In a cross between two different true breeding plants, bothphenotypes will be seen in which generation of offspring?F1F2PAll of the above
