What is crossing a homozygous dominant or homozygous recessive with a heterozygous?
There is a 50% chance of a homozygous dominant and a 50% chance of a heterozygous.
What genotype will be produced by a heterozygous?
The trait that would be expressed in a heterozygous genotype would be the dominant trait. If one allele is dominant then it will be expressed.
How would a baby change if one parent was homozygous dominant for all the traits and the other parent was heterozygous?
If one parent is homozygous dominant for all traits (carrying two dominant alleles for each trait), and the other parent is heterozygous (carrying one dominant and one recessive allele for each trait), there would be a 100% chance that the baby would inherit the dominant alleles from the homozygous dominant parent. Therefore, the baby would also be heterozygous for all the traits, carrying one dominant and one recessive allele for each trait.
Is it true that people who are heterozygous recessive allele but who have a normal phenotype eill not pass the harmful recessive allele to their kids?
It depends on the genotype of the childs other parent. If your partner is heterozygous as well then there is a 25% chance your child will be homozygous recessive. If they are homozygous dominant then none of your children will have the phenotype of the recessive trait. They will just possibly be carriers of the recessive allele.
What will happen to the recessive allele for PP?
there would be a 100% chance of it being heterozygous (Pp)

Therefore, the baby would also be heterozygous for all the traits, carrying one dominant and one recessive allele for each trait.
Which type of cross would produce 100 percent heterozygous offspring?
A cross between two homozygous parents will form a 100 percent chance of a heterozygous offspring. One homozygous parent must have the dominant allele, and the other must have the recessive allele. So, if the circumstances are correct, these characteristics will make for a 100 percent chance of a heterozygous offspring.
What is the probability that two heterozygous parents would have an offspring that produced round seeds?
The probability is 3/4 or 75%. If both parents are heterozygous for the seed shape trait (e.g., Rr), there is a 50% chance that each parent will pass on the dominant allele (R) for round seeds to the offspring. The probability of inheriting the dominant allele from both parents and producing round seeds is therefore (1/2) x (1/2) = 1/4 or 25%. Since there are two possible ways to inherit the dominant allele (from either parent), the total probability is 2 x (1/4) = 1/2 or 50%.

When 2 heterozygous parents breed what percentage of their offspring will be recessive?
Heteroygous means hybrid. So if both parents are heterozygous, they're both hybrids. Homozygous means that they are purebred. The chance is 50%. 25% chance of it being reccesive and 25% chance of being dominant. Thank you I'm only 11 and am in a advanced science class.
Can A negative mother and A positive father have O negative child?
Yes, because the "O" allele is recessive paired with an "A" allele. IF both parents are heterozygous: A+O- and A-O- the there is a 1/4 chance that the child will inherit both alleles. As I am just a high school student I cannot offer any professional answer

In crossing a homozygous recessive with a heterozygote what is the chance of getting a homozygous recessive phenotype in the F1 generation?
1/2 or 50%. The homozygous recessive gentoype contains two recessive alleles for the gene for a trait. So the homozygous recessive individual can pass on only recessive alleles to an offspring. The heterozygous individual has one dominant and one recessive allele for the gene for a trait. So the heterozygous individual can pass on either a dominant or a recessive allele to an offspring. So if an offspring inherits a recessive allele from the heterozygous parent, along with the recessive allele from the homozygous recessive parent, it will have the homozygous recessive genotype and phenotype.
When an allele mask the presence of another allele it is said to be?
Dominent. Simple- you have two types of Alleles, Dominent and Reccessive. Imagine a punnet square for the allele that causes albinoism (A). One parent has Aa, or one dominent allele and one reccessive allele for the trait. If the dominent skin-tone gene wasn't there (A), then it would be AA and he would be an albino. But since he has a dominent allele, he has normal color. If he made a baby with another Aa combination, they would have 25% chance of having an AA baby with no reccessive allele, a 50% chance of having an identical Aa combination, and a 25% chance of having an albino baby, AA.
