What is the ratios for a heterorozygous female and a homozygous dominant male?
The offspring will inherit one dominant allele from the homozygous dominant male and have a 50% chance of inheriting the dominant allele from the heterozygous female. Therefore, the ratio of offspring with the dominant allele to those without will be 1:1.
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.
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 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.
What is the ratios for a heterorozygous female and a homozygous dominant male?
The offspring will inherit one dominant allele from the homozygous dominant male and have a 50% chance of inheriting the dominant allele from the heterozygous female. Therefore, the ratio of offspring with the dominant allele to those without will be 1:1.
What is the probability of obtaining a dominant phenotype from self-fertilization of a heterozygous individual is?
The probability of obtaining a dominant phenotype from self-fertilization of a heterozygous individual is 75%. This is because in a heterozygous individual, there is a 50% chance of passing on the dominant allele and a 50% chance of passing on the recessive allele. With self-fertilization, the possible combinations are: 1 dominant allele (25%), 2 dominant alleles (50%), and 1 recessive allele (25%). Dominant phenotype will be expressed if there are one or more dominant alleles present.
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.
Do Parents with the dominant phenotype cannot have offspring with the recessive phenotypeous for a trait that is?
No. Parents with the dominant phenotype might be heterozygous in their genotype. This means they could carry both the dominant and recessive allele for a trait. So they could both pass the recessive allele to an offspring, who would then have the homozygous recessive genotype and recessive phenotype.
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.

Therefore, the baby would also be heterozygous for all the traits, carrying one dominant and one recessive allele for each trait.
If a man is heterozygous for the alleles that cause the condition and has children with a woman who lacks that defective allele?
If a man is heterozygous for the alleles that cause the condition and has children with a woman who lacks that defective allele, there is a 50% chance that each of their children will inherit the defective allele. This is because the man can pass on either the normal or defective allele, resulting in a 50% chance of passing on the defective allele.
Hurlington disease is an autosomal dominant disorder that affects the nervous system if a man is heterozygous for the alleles that cause the condition and has children with a woman who lacks then?
If a man who is heterozygous for the Hurlington disease alleles has children with a woman who does not have the alleles, there is a 50% chance that each of their children will inherit the disease allele. Since Hurlington disease is autosomal dominant, inheriting just one copy of the disease allele will result in the individual being affected by the disorder.
If a heterozygous plant for seed color is crossed with a homozygous recessive plant what is the probability of each seed color being produced?
100%
What are the chances of getting Huntington's if one of your parents are heterozygous?
If one of your parents is heterozygous for Huntington's disease, you have a 50% chance of inheriting the mutated gene responsible for the condition. This is because Huntington's is an autosomal dominant disorder, meaning that only one copy of the mutated gene is needed to develop the disease. If you inherit the normal allele from the heterozygous parent, you won't develop the disease.
What are the odds of inheriting a disease carried on a dominant allele?
If one parent carries the disease on a dominant allele, there is a 50% chance that their offspring will inherit the disease. Dominant alleles are always expressed in the phenotype, so if a parent has the disease, their offspring have a 50% chance of inheriting it.
