In a certain species plant the allele for tallness is dominant over the allele for shortness.to determine wether a tall plant is heterozygous should be crossed with a?
To determine whether a tall plant is heterozygous, it should be crossed with a homozygous recessive plant (short plant). If any offspring are short, the tall plant must be heterozygous; if all offspring are tall, the tall plant is likely homozygous dominant. This test cross allows for the observation of inheritance patterns in the offspring.
When is a character said to be dominant?
Hello there, Dominant and recessive traits can be tested by reproduction. For example, if I was to grow a tall pea plant and a short pea plant that are true breeds, and if I was to cross pollinate them to form a hybrid pea plant, the new pea plant offspring would exhibit the dominant trait out of tall and short (In this case tall). When reproduction occurs, two alleles for a given gene will be introduced, and only the dominant trait will be used and exhibited by the offspring. That way, if we want to determine whether a trait is dominant, we will need to test through reproduction. Hope this helps!
Why did you color the offspring plant a different color than the tall parent plant?
The different color given to the offspring plant is a visual aid to help differentiate it from the parent plant when illustrating genetic traits or characteristics being passed down from one generation to the next. This color difference can make it easier to track and identify specific traits as they are inherited and expressed in the offspring.
When you think of the trait of the parent plants why is this result surprising?
what trait or traits did the plant in the f generation to the offspring in the F2 gen. what did the difference in the F1 and F2 offspring show Mandel
Are all tall peas always purebred for tallness?
No, not all tall pea plants are purebred for tallness. In Mendel's experiments with pea plants, tallness is a dominant trait, but if a tall plant is heterozygous (having one allele for tallness and one for shortness), it can produce offspring that are either tall or short. Only plants that are homozygous for the tall trait (having two alleles for tallness) will consistently produce tall offspring. Thus, genetic testing or breeding records are needed to determine if a tall pea plant is purebred.
What must be true for a cross between a tall plant and a short plant to produce any short plants?
Both the tall plant and short plant must be heterozygous for the height trait, meaning they each carry one dominant and one recessive allele. When they produce offspring, there is a 25% chance of obtaining a short plant by inheriting two recessive alleles for the height trait.
Could 2 short haired rabbits produce a long-haired offspring?
yes

What must true for a cross between a tall plant and a short plant to produce any short plants?
the tall plant must be heterozygous.
What must br true for a cross between a tall plant and a short plant to produce any short plants?
The tall plant must be heterozygous.
In certain plants tall is dominant to short If a heterozygous plant is crossed with a homozygous tall plant what is the probability that the offspring will be short?
0 (there is no chance it will be short since tall is dominant over short). Hope this helps! - Biology Student
What perform a testcross 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!
When Mendel crossed a truebreeding short plant with a truebreeding tall plant all the offspring were tall Which term describes the gene for tallness?
dominant
What do true-breeding pea plants always produce?
True-breeding pea plants always produce offspring with the same traits as the parent plant. This is because they are homozygous for the trait of interest, resulting in consistent expression in the offspring generation.
Is it possible for two short-haired guinea pigs to produce long haired offspring?
if their is a long haired relative
When Mendel crossed a truebreeding short plant with a true -breeding tall plant all the offspring were tall which term describes the gene for tallness?
