When Gregor Mendel crossed purebred short plants with purebred tall plants all of the offspring were?
tall.
When he crossed to pea plants that have different traits of the same characteristic how was Mandel able to select which plants would be crossed to produce offspring?
visual inspection of phenotypic traits.
Suppose two white flowered pea plants are crossed and produce 1000 offspring how many of those offspring would you expect to have white flowers?
224
What did Gregor Mendel do study different characteristics in his genetics experiments?
Gregor Mendel took two true-breeding plants with contrasting traits and cross-pollinated them, producing offspring with genes for both characteristics. He used selective breeding.
When gregor mendel crossed true breeding purple flowered plants with true breeding white flowered plants all of the offspring were purple because?
Ture
When parent plants are crossed how do scientists refer to the first generation of offspring?
F1
When plants that are true breeding for different traits of a characteristic are crossed the offspring are called?
first-generation plants
When Gregor Mendel crossed purebred short plants with purebred tall plants all of the offspring were?
tall.
Two true-breeding pea plants are crossed one with purple flowers and the other with white. Their offspring are?
If two true-breeding pea plants are crossed their offspring will show the dominant trait. The flowers will be purple or light purple.
When he crossed to pea plants that have different traits of the same characteristic how was Mandel able to select which plants would be crossed to produce offspring?
visual inspection of phenotypic traits.
The offspring of two true-breeding plants is .?
When two true-breeding plants are crossed, only one result is possible.
purple petal color in pea plants is dominant to white petal color two heterozygous pea plants are crossed what is the ratio of the offspring with white petals to the number total number of offspring?
3:1 ratio Two pea plants, both heterozygous for flower color, are crossed. The offspring will show the dominant purple coloration in a 3:1 ratio
Two plants are crossed resulting in offspring with 3 to 1 ratio for a particular trait?
that the parents were true-breeding for contrasting traits. NOT TRUE. If so, all the offspring would be identical genotypes. Think of a classic cross that gives you a 3:1 ratio and write it out. It would suggest that the parents were both heterozygous for a single trait.
