How would the smiley face change if one parent were homozygous dominant for all the traits while the other was heterozygous?
If one parent is homozygous dominant for all traits, they can only pass on dominant alleles, while the heterozygous parent can pass on either dominant or recessive alleles. This would result in a combination of offspring that are either homozygous dominant or heterozygous for each trait, but none would be homozygous recessive. Consequently, the overall phenotype of the smiley face would predominantly express the dominant traits.
What are the possible offspring outcome if parent one Tt crosses with parent to tt?
A heterozygous cross.Tt X TtOne homozygous dominant--TTTwo heterozygous dominant---TtOne homozygous recessive--ttAll on a statistical average outcome.
How the smiley faces change if one of the parents were homozyous domiant for all the traits while the other was heterozygous?
If one parent is homozygous dominant for all traits (AA) and the other is heterozygous (Aa), the offspring will inherit one dominant allele from the homozygous parent and either a dominant or recessive allele from the heterozygous parent. This results in a 50% chance of the offspring being homozygous dominant (AA) and a 50% chance of being heterozygous (Aa). Therefore, all offspring will express the dominant traits, but their genotypes will vary between AA and Aa. As a result, the smiley faces representing the traits will be uniform in appearance but may differ in genetic makeup.
What determines whether an organism is heterozygous or homozygous dominant?
The second allele. If a plant is heterozygous tall, it is Tt. In this case, the dominant trait is tall, T and recessive is short, t. There are two options for it to be dominant, heterozygous (Tt) or homozygous (TT)
What is the probabilty that the offspring of a homozygous domiant idiviual and a homozygous recessive indiviual will exbhit the domaint phenotype?
If one parent is homozygous dominant (AA) and the other parent is homozygous recessive (aa), all offspring will inherit one dominant allele and display the dominant phenotype. Therefore, the probability of their offspring exhibiting the dominant phenotype is 100%.

A parent that is homozygous for a dominant trait is crossed with a parent that is homozygous for the recessive trait What percentage of the offspring will display the dominant trait?
100% of the offspring will display the dominant trait because the homozygous dominant parent can only pass on the dominant allele. The offspring will inherit one dominant allele from the dominant parent and one recessive allele from the recessive parent, resulting in a heterozygous genotype expressing the dominant 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.

What percentage of genotypes would most likely be found in the f1 generation offspring?
If the parent generation consisted of a homozygous dominant parent and a homozygous recessive parent, then the F1 generation would be 100% heterozygous.
When can you use a test cross?
A test cross is used to determine the genotype of an organism exhibiting a dominant phenotype. By crossing this organism with a homozygous recessive individual, the offspring's phenotypes reveal whether the dominant organism is homozygous or heterozygous. If any recessive phenotypes appear in the offspring, the dominant parent is heterozygous; if all offspring display the dominant phenotype, the parent is likely homozygous. This method is commonly employed in genetics to assess inheritance patterns.
If a homozygous dominant parent and a heterozygous parent are crossed what percentage of the offspring are expected to be homozygous dominant?
Rr
What happens to the alleles between the P generation and the F2 generation?
In the P generation, one parent is homozygous dominant and the other parent is homozygous recessive. In the F1 generation, the product of a cross between the P generation, the offspring are all heterozygous. In the F2 generation, the product of a cross between the F1 generation, the expected result is 1/4 homozygous dominant, 1/2 heterozygous, and 1/4 homozygous recessive.
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).
