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)
1/16
When both parents are heterozygous for seed shape (Rr, where R is the allele for round seeds and r is the allele for wrinkled seeds), the probability of producing an offspring with round seeds can be determined using a Punnett square. The possible genotypes are RR, Rr, Rr, and rr. Thus, there are three combinations (RR and Rr) that result in round seeds out of four total combinations. Therefore, the probability of having an offspring with round seeds is 3 out of 4, or 75%.

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

The chance of producing an offspring with the dominant phenotype for height (Tt) and the recessive phenotype for color (gg) is 1/4 or 25%. This is because the genotype for height is determined by one gene and the genotype for color is determined by a different gene, so they are inherited independently of each other.
