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.
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.
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.
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.
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.

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 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.
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.
Dimples are a dominant characteristic If one parent does not have dimples and one parent is heterozygous for dimples what chance does a child have for getting dimples?
The child has a 50% chance of inheriting dimples. This is because dimples are a dominant trait, so if one parent is heterozygous for dimples, they will have one dominant allele for dimples to pass on to their child. The child would need to inherit this dominant allele from the heterozygous parent in order to express the trait.
