Genetics Problems

1. In some flowers, red and white color is codominant. Flowers and be red (RR), white (rr) or pink (Rr)

If two pink flowers are crossed, what percentage of the offspring will also be pink?

If a red and a white flower are crossed, what percentage of the offspring will be pink?

2. A man who has normal vision X Y is married to a woman who is colorblind. X X

How many of their children will be colorblind and what is their sex?

3. In pea plants, tall is dominant to short.
A heterozygous tall (Tt) is crossed with a short (tt) plant. What percentage of their offspring will be short?

 

Two short plants are crossed, what percentage of their offspring will be short?

 

Two heterozygous plants are crossed, what percentage of their offspring will be tall?

 

4. A man with type AB blood is married to a woman with type AB blood. What blood types are possible among their children and in what proportion?

5. A man with type O blood is married to a woman with type A blood (she can be either genotype AO or AA). What blood types are possible among their children?

6. Determine the genotypes in the pedigree below. The trait being studied is the tongue rolling ability. Those who cannot roll their tongue are recessive (tt)
