In humans straight toes S is dominant over curled toes s What would be the result of a cross between a recessive male and a heterozygous female?

The resulting offspring will have 50% chance of having straight toes and being heterozygous, and 50% chance of having curled toes and being recessive.

What is the difference between homzyguos and heterozyous?
Homozygous recessive: is when the genes are both recessive Homozygous dominant: is when the genes are both dominant (traits show) Heterozygous dominant: is when one gene is dominant and one is recessive (traits show) Heterozygous recessive: is the same as heterozygous dominant but the dominant genes are inactive
What is the differences between homozygous dominant and homozygous recessive and heterozygous?
A homozygous dominant genotype means that both alleles for a trait are dominant. A heterozygous genotype means that one allele is dominant and the other is recessive. A heterozygous genotype will express the dominant phenotype, not the recessive phenotype.
What is the result of a cross between an individual who is homozygous dominant and another who is homozygous recessive for a trait?
All the offspring will be heterozygous with a phenotype showing the dominant trait. Let the alleles be H (dominant) and h (recessive). All the gametes from the first individual will be H, and from the other, h. Thus all the offspring must be Hh.
What happens to alleles between the p generation and 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 name for a cross between an individual of unknown genotype and a homozygous recessive?
A cross between a homozygous recessive and an individual of unknown genotype is called a test cross.The homozygous recessive can only pass on a recessive allele to the offspring, and so any recessive in the other parent will show up in the phenotype (detectable characteristics) of some of the offspring.
What is the difference between homzyguos and heterozyous?
Homozygous recessive: is when the genes are both recessive Homozygous dominant: is when the genes are both dominant (traits show) Heterozygous dominant: is when one gene is dominant and one is recessive (traits show) Heterozygous recessive: is the same as heterozygous dominant but the dominant genes are inactive
What is the opposite of homozygous of dominant?
heterozygous recessive
What is the difference between a homozygous dominant homozygous recessive and heterozygous individual?
They are the same
What is the differences between homozygous dominant and homozygous recessive and heterozygous?
A homozygous dominant genotype means that both alleles for a trait are dominant. A heterozygous genotype means that one allele is dominant and the other is recessive. A heterozygous genotype will express the dominant phenotype, not the recessive phenotype.
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).
What is the difference between a homozygous trait and a heterozygous trait and can you please provide an example for each?
a homozygous trait is when an offspring has either both dominant genes or both recessive genes from its parents. a heterozygous trait is when an offspring has both dominant and recessive genes. for example: a long-tailed cat is dominant and a short-tailed cat is recessive. the long-tailed cat (homozygous dominant) had offsprings with the short-tailed cat (homozygous recessive). by doing the punnett square, 100% of their offspring will be heterozygous.
How would a recessive trait show up in a cross between two individuals with a dominant phenotype?
If both the individuals are heterozygous dominant then the probability of recessive (homozygous) phenotypic offspring would be 1:4
What is the result of a cross between an individual who is homozygous dominant and another who is homozygous recessive for a trait?
All the offspring will be heterozygous with a phenotype showing the dominant trait. Let the alleles be H (dominant) and h (recessive). All the gametes from the first individual will be H, and from the other, h. Thus all the offspring must be Hh.
What is the difference between heterozygous and homozygous alleles?
You're looking at a gene which contains 2 alleles (meaning variations of that gene). Let's call it "A."Remember that you get 2 copies of EACH gene (one from mom, one from dad).
What is the relationship between dominant and recessive alleles in a heterozygous organisms?
it means there is one of each. in a homozygous gene it means that there are two of the same. for example if "t" repressents a recessive trait and "T" represents a dominant trait, then an organism with a gene that is tT would be considered heterozygous, and a gene that is TT or tt would be considered homozygous or "pure bred"
Show the cross between 2 heterozygous dogs. black fur B is dominant to brown fur b?
BbxBb = 25% homozygous BB; 50 % heterozygous Bb, and 25% homozygous recessive bb.
The difference between a dominate and a recessive trait is?
A trait is dominant if it continues to be expressed in the heterozygous as well as the homozygous state. Recessivetraits are only expressed in the homozygous state.
