Each parent contributes 50% of the genetic make-up of the offspring.
25%
The probability is 50%. There are four probabilities: dominant homozygous, recessive homozygous, or heterozygous.
50%
75%. Explanation: if both parents are carriers than their Gametes would be Dd x Dd, resulting in DD (1/4), Dd (2/4), and dd(1/4), meaning that there is a 25% chance that they will have a child that has the disorder. DD = A normal child that lacks the recessive gene, therefore not a carrier Dd = A normal child that carries the recessive gene dd = A child with the disorder + carries the gene, hence the child's future offspring will carry it as well.

I am unsure of the answer to this question, but I feel the need to remove the previous ridiculous answer stating that "women with down syndrome are sterile." They ARE indeed fertile. I am in search of the same information, and will be editing this post once I find the correct answer.
From the cross Aa x Aa, the probability of producing a homozygous dominant offspring is 1/4 or (0.25).
25%
you have a 50/50 chance of producing both a male and female offspring, it really depends on whether or not your offspring's DNA will have XY chromosomes (male) or XX chromosomes (female)

Here are the four possibilities: AA Aa Aa aa Therefore there is a 25% chance of producing a homozygous dominant offspring (AA).

Many possible genotypes, producing ,any possible phenotypes.
If two organisms, each with genotypes tt+gg mate. What is the chance of producing and offspring that has the dominant phenotype for height (t) and the recessive phenotype for color (g)
Many possible genotypes, producing ,any possible phenotypes.
producing or capable of producing offspring
Chlamydiae reproduce by binary fission, producing two offspring.
