When Mendel crossed pea plants with green pods with those with yellow pods, the offspring all had green pods if the green pod parent was homozygous. If the green pod parent was heterozygous, then half the offspring had green pods and half had yellow pods.
If yellow is recessive all offspring will be yellow.
If yellow is dominant then the ratio of yellow to green podded individuals will hinge on the genetics of the parents and cannot be assessed.
Mendel did multiple crosses of pea plants to study different genes. When he was examining the genes for color, though, he crossed true-breeding plants bearing yellow peas (the dominant strain) with those bearing green seeds (the recessive strain).
all green
When Mendel crossed a true-breeding short plant with a true-breeding tall plant, all the offspring were tall. Which term describes the gene for tallness?
They produce many offspring
what Mendel got is two tall plants, im guessing i got that from a science book so
When two true-breeding plants are crossed, only one result is possible.
Mendel did his experiments by using pea plants with various traits like the color of the flower, the shape of the seeds, the height of the plants etc and studied how those traits behave when crossed. For example, what happens when a short plant with red color flowers was crossed with a tall plant with purple colored flower etc.
tall.
because it helped Mendel discover which plants would be crossed to produce offspring.

When Mendel crossed a true-breeding short plant with a true-breeding tall plant, all the offspring were tall. Which term describes the gene for tallness?
I think not as tall is the dominant allele here.T = tallt = shortTT X ttall would beTt======and tall.
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.
