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 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.
Which type of cross would produce 100 percent heterozygous offspring?
A cross between two homozygous parents will form a 100 percent chance of a heterozygous offspring. One homozygous parent must have the dominant allele, and the other must have the recessive allele. So, if the circumstances are correct, these characteristics will make for a 100 percent chance of a heterozygous offspring.
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 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 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.
What is the difference between a homozygous dominant homozygous recessive and heterozygous individual?
They are the same
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 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).
Which type of cross would produce 100 percent heterozygous offspring?
A cross between two homozygous parents will form a 100 percent chance of a heterozygous offspring. One homozygous parent must have the dominant allele, and the other must have the recessive allele. So, if the circumstances are correct, these characteristics will make for a 100 percent chance of a heterozygous offspring.
What is the opposite of homozygous of dominant?
heterozygous recessive
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 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
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
