From the cross AA x AA the probability of producing a homozygous dominant offspring is?
From the cross Aa x Aa, the probability of producing a homozygous dominant offspring is 1/4 or (0.25).
In the cross AA x AA what is the probability of obtaining AA offspring?
50% will be tall
What is the probability that a cross between a hybrid pea plant with round seeds and one with wrinkled seeds will produce offspring with wrinkled seeds?
The probability that an offspring will have wrinkled seeds is 2 in 4 or 50%
What is the probability of a homozygous recessive offspring?
It depends. If it's a heterozygous cross, (Tt x Tt), there's a 25% chance. If it's a homozygous dominant cross (TT x TT), the chance is 0%. Neither parent has the alleles for a recessive trait, so none of their offspring can have the recessive trait. If it's a homozygous recessive cross (tt x tt), there's a 100% chance. The only alleles the parents can pass on are recessive.
From the cross AA X AA the probability of producing a homozygous dominat offspring is?
Here are the four possibilities: AA Aa Aa aa Therefore there is a 25% chance of producing a homozygous dominant offspring (AA).
You perform a test cross on a tall pea plant half the offspring are short what conclusion can you draw from this outcome?
The genotype of the tall pea plant is heterozygous
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.
5 An F1 plant that is homozygous for shortness is crossed with a heterozygous F1 plant What is the probability that a seed from the cross will produce a tall plant?
there is a 50% chance that the offspring will be tall.
In a dihybrid cross between individual with the genotype RRYYand an individual with the genotype rryy all of the offspring with have the genotype?
RrYy
When hybrids for a certain characteristic are crossed Aa x Aa the recessive genotype AA may appear in some of the offspring because of what?
Probability is the term for the chance that any specific genotype will occur in the offspring from the mating of parents. Typically the capital letter A (in this example) represents the dominant allele as opposed to the recessive allele. The probability of the possible genotypes in a monohybrid cross is 1AA:2Aa:1aa. The probability of AA is .25 or 25%.
What is the probability of a hybrid offspring in a cross between two hybrid plants?
The hybrid is the offspring so the probability is 1.
What does a punnet square mean?
The Punnett square is a diagram that is used to predict the outcome of a particular cross or breeding experiment. It is used by biologists to determine the probability of an offspring having a particular genotype.
What would be the results from a cross between a female rabbit with genotype Cc and a male rabbit with the genotype cc create a Punnet square showing this cross?
50% of the rabbits will be cc and 50% of the rabbits will be Cc. The punnet square is simple because one rabbit is homozygous recessive and the other is heterozygous. The genotype is then defined by the heterozygous (Cc) rabbit.
In a cross between a pea plant with the genotype TT and a pea plant with the genotype Tt percent of the offspring will be Tt.?
false
How could the botanist best determine whether the genotype of the green-pod plant is homozygous or heterozygous?
A cross between a plant of unknown genotype and one that is known to be homozygous recessive is called a test cross because the recessive homozygote testswhether there are any recessive alleles in the unknown. Because the recessive homozygote will contribute an allele for the recessive characteristic to each offspring, the second allele (from the unknown genotype) will determine the offspring's phenotype.
When trying to find an unknown genotype you must perform a?
Perform a test cross. Cross the organism with an organism with a homozygous recessive genotype and use the phenotypes of the offspring and a Punnett square to figure out the unknown genotype.
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
