please help with following questions

Use this information to answer the following question Three babies were mixed up when hospital aides gave them to the wrong parents. To correct the situation and return the offspring to their rightful parents, the blood types of both parents and babies were taken. The results are recorded below. Parents Blood Type Baby Blood Type A and B 1 B B and O 2 A AB and B 3 AB Baby 2 later married Baby 3. What is the possibility that their first child will have type A blood? O 1) 25% • 2) 50% O 3) 75% • 4) 0%
The technology of transferring a gene from a bacterium into a plant is based on the principal that O 1) all genes have the same basic chemical components • 2) the phenotype of an organism is not altered when one gene is exchanged for another • 3) the genotypes of the bacterium and green plant are the same 4) all genes carry the same genetic information
Use the following additional information to answer the next question. A plant heterogeneous for both traits was crossed with a plant homozygous recessive for both traits. What percentage of the offspring produced would be expected to display at least one of the dominant traits? O 1} 50% O 2) 75% • 3) 100% • 4) 25%
In the type of albinism describes above, because melanin production is controlled by an autosomal gene, it is expected that • 1) albinism will occur more frequently among males than females • 2) males will inherit albinism from their mother • 3) males will develop albinism as they mature • 4) albinism will occur with equal frequencies among males and females

When organisms look alike are they always twins?
Question options:
Yes when organisms look alike they are always twins. You can tell because their major features will be identical.
No when organisms look alike they are not always twins. You need to look at their DNA sequence to determine if they are twins or not.
Yes, when organisms look alike they are always twins. You done even need to look alike and still be a twin. This happens often with the use of fertility drugs.
No when organisms look alike they are not always twins. Even if you look at their DNA sequence to determine this it may not be conclusive.
How can you identify twins? Question options:
a)
look the same
b)
DNA fingerprints match
c)
same parents
d)
fingerprints match
Which codon controlled eye colour? Question options:
a)
Condon 2 - bands 2 to 4

Condon 3 - bands 7 to 9
d)
Condon 1 - bands 1 to 3
Which codon controlled skin colour? Question options:
Condon 1 - bands 1 to 3
Condon 2 - bands 2 to 4
Condon 3 - bands 7 to 9
Condon 6 - bands 16-18
Which codon controlled spots?
Question options:
a)
Condon 2 - bands 2 to 4
b)
Condon 1 - bands 1 to 3
c)
Condon 6 - bands 16-18

Please help, thank you!
What generalization can be made about the number of times an event must occur to get the actual results near the predicted values, or exactly as predicted?
Question options:
The generalization is that the less the number of times an event occurs, the closer the actual results will come to the predicted results.
The generalization is that the greater the number of times an event occurs,has no impact to the predicted results.
The generalization is that the greater the number of times an event occurs, the closer the actual results will come to the predicted results.
The generalization is that the greater the number of times an event occurs, the further the actual results will be to the predicted results.
Theoretically, if you toss two coins together forty-eight times, how many times should you get (show work)
a. two heads b. a head and a tail c. two tails
The product rule states
Question options:
that the probability of two independent events occurring simultaneously is equal to the product of them occurring separately
if two outcomes are independent, the probability that both will not occur is their product
if two outcomes are dependent, the probability that both will occur is their product
that the probability of two independent events occurring simultaneously is not equal to the product of them occurring separately
Which of the following statements does not represent the general rule for determining the probability of inheriting two specific traits at the same time?
Question 17 options:
Treat Di-hybrid crosses as if they were monohybrid crosses. Multiply the chances of the two events occurring independently to determine the chance of them occurring together.
You can find out the probability of inheriting two traits by finding out the probability of each one individually then multiplying them together.
The multiplication rule states that if two outcomes are independent (not linked), the probability that both will occur is their product. P(AB)=P(A)×P(B)
All the above statements are accurate.
