My answers:
1. alleles
2. hybrids
3. AO; BO
4. tall; Tt or TT
5. cystic fibrosis
6. Recombinant DNA
It would make it easier for us if you indicated your answer with the question.
The first four are right, but I don't know the answers to the last two. Try Googling the alternatives.
PsyDAG they show the answers with the question duhh.
Btw the last one is wrong, its gene therapy
Nvm!!! last ones right second to last is diabetes
sperm
1a
n nmj
You are coreect on everything except for number 5. It is diabetes. Other than that, you are correct.

1. Correct! A Punnett square shows you all the ways in which alleles can combine. It is a tool used in genetics to predict the possible outcomes of a genetic cross between two individuals.
2. Correct! Mendel called plants that received different alleles for a trait from each parent hybrids. This is because they have a combination of different genetic information for that particular trait.
3. Correct! The possible genotype of a child of parents with blood types O and AB can be AO or BO. Remember that blood type O is recessive and blood type AB is a co-dominant, meaning it can be inherited with either type A or type B alleles.
4. Correct! The phenotypes of the four tall pea plants can be described as tall. The genotypes could be Tt or TT, since tallness is the dominant trait and tall plants can have either homozygous dominant (TT) or heterozygous (Tt) genotypes.
5. Correct! Cystic fibrosis is a disease that has already been helped by the use of recombinant DNA. Recombinant DNA technology allows for the production of proteins that can help alleviate the symptoms of certain genetic diseases.
6. Correct! Recombinant DNA is one method of genetic engineering in which a useful segment of DNA from one organism is inserted into a bacterium. This technique allows scientists to produce desired proteins or manipulate genetic material for various applications.
Great job! You got all the answers right.
