What cross should a scientist perform in order to determine if the organism is heterozygous or homozygous dominant?
Scientists use a test cross to determine if an organism is heterozygous or homozygous dominant.
If a homozygous dominant parent and a heterozygous parent are crossed what percentage of the offspring are expected to be homozygous dominant?
Rr
If a homozygous dominant is crossed with a homozygous recessive for a given trait the offspring will be?
The phenotype will show the dominant trait. All dominant traits mask recessive ones; If the genotype is heterozygous (One dominant and one recessive) the organism's phenotype will be dominant.
Hybrid organisms prodused from a cross between two pure-breeding organisms belong to which generation is F1?
Hybrids from a cross of parental (P) generation, of homozygous parents (one is homozygous recessive, the second one is homozygous dominant) do belong to F1 generation, yes. Their genotype is heterozygous.
To determine if a particular plant is homozygous or heterozygous you would have to test cross with a?
Homozygous recessive plant
What cross should a scientist perform in order to determine if the organism is heterozygous or homozygous dominant?
Scientists use a test cross to determine if an organism is heterozygous or homozygous dominant.
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.
What cross shows homozygous dominant mating with heterozygous?
AA (dominant) mating with aa (recessive) -----> Aa
What is the offspring if you cross two heterozygous Tt tall plants?
You get one homozygous dominant (TT), one homozygous recessive (tt), and two heterozygous (Tt).
What is a plant with two dominant or two recessive alleles said to be?
Heterozygous alleles are used to describe the 'parents' when creating a test cross chart. When completing a test cross there is more than comparing alleles, you are really comparing genetics. Heterozygous YY or yy versus Homozygous Yy, is just the first to consider.
If a homozygous dominant parent and a heterozygous parent are crossed what percentage of the offspring are expected to be homozygous dominant?
Rr
What is the expected genotypic ratio for a one factor cross of two hybrid organisms?
1 homozygous dominant: 2 heterozygous: 1 homozygous recessive
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 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 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.
If a homozygous dominant is crossed with a homozygous recessive for a given trait the offspring will be?
The phenotype will show the dominant trait. All dominant traits mask recessive ones; If the genotype is heterozygous (One dominant and one recessive) the organism's phenotype will be dominant.
What is the height of the f1 plant if the tall plant AABBCC is crossed with a base height plant aabbcc?
In such a cross, the F1 plants will always be tall, because that is the dominant allele. In the cross described, a homozygous dominant plant was crossed with a homozygous recessive plant; a cross that produces 100% heterozygous offspring. (AaBbCc)
