Susie is very short, but she loves to play basketball.  She knows that her dreams of playing in the WMBA can not come true because of the homozygous recessive alleles.  If Susie wanted to increase her odds of having a tall child, what genotype should her husband have to give her the BEST chance at having a child in the MBA or WMBA.

• Two recessive alleles will increase her odds by 75% 
• Two dominant alleles to increase her odds by 100%
• One dominant and one recessive allele that would increase her odds by 100%
• She always has a 0% chance no matter the genotype of her husband.
