If the male parent cell is heterozygous for a traitTt what alleles could the sperm cells possibly have?

If a man has the genotype Tt, then he is heterozygous. Homozygous would be TT or tt. If a man has Tt, then he can either donate a T or a t to the sperm, but not both.

If the male parent is heterozygous for a trait what alleles for each sperm cell possibly have?
each sperm cell could either have the dominant or the recessive allele for that trait
Is AA an homozygous or an heterozygous?
AA could be either homozygous or heterozygous, depending on whether the individual inherited the same allele (A) from both parents (homozygous) or different alleles (Aa) from each parent (heterozygous).
What is the difference between a herezygous and a homozygous?
"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).
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.
What is the genotype of a child if the mother is homozygous for the dominant trait and the father is homozygous for the recessive trait?
The dominant parent is most likely homozygous dominant, and the recessive parent has only the homozygous genotype. So the dominant parent can pass on only dominant alleles for this trait, and the recessive parent can pass on only recessive alleles for this trait. So all of the offspring would be heterozygous and have the dominant phenotype.
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.
If one parent has two dominant alleles and another parent has two recessive alleles the offspring will have?

What are traits that are hidden called?
Recessive traits can be hidden if the organism inherits one dominant and one recessive allele (i.e. is heterozygous) for a gene. If a heterozygous organism mates with another heterozygous organism for the same trait, the recessive trait may be expressed in their offspring, which would mean that the offspring inherited two recessive alleles, one from each parent.
Why does each parent organism in the f1 generation have four alleles listed in figure 6.17?
Each parent has two genes with two alleles so there are four alleles.
If one parent has two dominant alleles and another parent has two recessive alleles the offspring will be what?
yes I don't know
How do you figure out the combinations for a heterozygous parent for two traits?
A heterozygous parent with two traits on random mating will have the off springs in dihybrid ratios of genetic segregation.
The offspring of two parents that are heterozygous for a given trait have a percent chance of being homozygous for that trait?
This would result in 1 heterozygous offspring. You can think of it like this: If the first parent is homozygous it would have AA alleles, the second heterozygous parent would be AB. When they mix genetically it would result in 4 combinations: AA, AA, AA, AB. As there is only one B there can only be one heterozygous offspring. This is not expected it is certain.
