Green is the dominant trait in this cross. Mendel's results demonstrate that when a dominant allele (for green pods) is present, it masks the effect of the recessive allele (for yellow pods), resulting in all offspring exhibiting the dominant phenotype. Thus, the true yellow podded plant contributes a recessive allele that does not express in the presence of the dominant green allele.
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.
only green-podded plants. Incorrect^ Letter D on the sheet, about three-quarters green-podded plants and one-quarter yellow-podded plants.
When Mendel crossed true-breeding pea plants with round yellow seeds (dominant traits) and those with wrinkled green seeds (recessive traits), the offspring displayed round yellow seeds because the alleles for round shape and yellow color are dominant over the alleles for wrinkled shape and green color. This resulted in a phenotype where the dominant traits mask the effects of the recessive ones in the F1 generation. Thus, all the hybrid offspring exhibited the dominant traits of round yellow seeds.
This is a basic Mendel cross where the master himself found out that yellow was the dominant color to green. Many years later we found out that there is another gene involved and that the colors have to do with chlorophyll - not just color. If a pure green is crossed to a purebred yellow, then all the offspring will be yellow. However they do carry the green gene since if these yellow offspring are self-fertilized, they will produce the standard 3/4 yellow and 1/4 green phenotypes.
The genotype of the offspring with yellow pods is likely homozygous dominant (YY) or heterozygous (Yy), assuming yellow pods are dominant over green. The possible genotypes of the offspring with green pods would be homozygous recessive (yy), as green is the recessive trait. If both yellow-podded parents are heterozygous (Yy), some offspring could also be yellow (YY or Yy) while others could be green (yy).
When Mendel bred green pea plants with yellow pea plants and all the offspring were yellow, it indicated that the yellow trait is dominant over the green trait. This means that the yellow allele masks the expression of the green allele in the offspring. As a result, even though the green allele is present, it does not manifest in the phenotype of the plants. This observation was crucial in understanding the basic principles of inheritance.
Homozygous yellow peas have two identical alleles for yellow color (YY), while heterozygous yellow peas have one yellow allele and one non-yellow allele (Yy). This means that homozygous yellow peas will always produce yellow offspring when crossed, while heterozygous yellow peas have a 50% chance of producing non-yellow offspring when crossed with another heterozygous pea plant.
Gregor Mendel concluded that inheritance is determined by discrete units or factors (genes) that are passed down from parents to offspring. He also proposed the principles of segregation and independent assortment, which explain how traits are inherited. Mendel's work laid the foundation for the field of genetics.
becoz the expression for a white-coloured allele is dominant while that for a yellow-coloured is recessive.
In pea plants, the yellow color (Y) is typically dominant over the green color (y). If a heterozygous yellow pea plant (Yy) is crossed with a green pea plant (yy), the possible genotypes of the offspring would be 50% heterozygous yellow (Yy) and 50% homozygous green (yy). Therefore, the offspring would exhibit a 50% chance of being yellow and a 50% chance of being green.
The seeds of the offspring are yellow because the allele for yellow seeds is dominant and the allele for green seeds is recessive. If you use a Punnett Square to show the way the possible gametes would pollinate, it would look something like this: Y Y Yy Yy Yy Yy y y Actually the small y's are supposed to be on the left side, but I can't figure out how to do it on this site. If there is one dominant allele, than that is the trait that shows up.
You get a yellow leprechaun.
