Question

If a person with AB blood (genotype IAIB) produced an offspring with a person who’s IAi, what’s the chance that the offspring will have A blood? Give your answer as a percentage. Use the table to make a Punnett square to show your work. Can you show me in a chart to break it down to get that answer which is 50%.

Answer 1

Answer:

50% of getting A blood type

Explanation:

Using a punnet square you have (sorry cant do a square)

    IA            IB

IA

i

Then you you add all the possible combinations from both parents genes

              IA               IB

IA          IA IA           IA IB

i            IA i               IB i

You now have a 50% chance of A type blood because the lowercase (i) wont change the blood type outcome because the IA over shines it.
