A red flower(WW) and white flower(ww) (P1) have the ability to create pink flowers in thier offsprings (F1). What type of
I know if is an incomplete dominance at 50 percent. But i am having a problem with the Punnett Square
Introduction :-
Incomplete dominance is a type of genetic interaction in which the phenotype of the offspring is a mixture of the two parental phenotypes, rather than being a straightforward expression of one dominant or recessive allele. This occurs when the alleles from the two parents do not have a clear dominant-recessive relationship and both contribute equally to the phenotype of the offspring.

- The image shows a pair of homologous chromosomes from a single parent before gamete production. M1 and M2 are maternal chromosomes, while P1 and P2 are paternal chromosomes. Two traits are shown: D represents seed color (D – green, d – yellow), while F represents flower color (F – purple, f – white). These two traits follow the patterns of basic Mendelian genetics. During crossing-over between the M2 F allele and the P1 f allele, a mutation occurred and the portion of P1 did not reattach to the chromosome. Which of the following explains what would happen to the proportion of white flowers in a population resulting from this mutation? A - There would be an increase in the proportion of white flowers because the f allele is distributed to more gametes. B - There would be a decrease in the proportion of white flowers because the f allele is not distributed to as many gametes. C - There would be an increase in the proportion of white flowers because the f allele would not be masked by the…arrow_forward# of Green Leaves _________111______________ # of White Leaves ___________35______________ If a heterozygous F1 Tobacco plant was crossed to an albino plant, what is the expected number of green and white plants in the next generation?

You perform the following cross and observe the progeny. PPBb x Ppbb To determine if the difference between the observed and expected results are due to change, you perform a chi-squared analysis.

- To play Jeopardy, the answer is given. You must supply the question. Choose the best question for the following answer: Mutant allele causing malfunction of the wild-type allele, giving rise to a dominant phenotype. What is codominance? What is incomplete dominance? O What is dominant negative? O What is haploinsufficiency?arrow_forwardThe genes for red (RR) and white (rr) flowers have incomplete dominance. What are the percentages and color for the offspring of the cross Rr X Rr?arrow_forwardA white flower is crossed with a purple flower, and the offspring exhibit incomplete dominance. A) What is the phenotypic ratio of the F1 generation offspring? What is the genotypic ratio of the F1 generation offspring? B) What is the phenotypic ratio of the F2 generation offspring? What is the genotypic ratio of the F2 generation offspring? Answer and work:arrow_forward
- The diagram shows a plant that is heterozygous for two genes. G = yellow; g = green; R = round; r = wrinkled G Four different types of gametes are produced by a heterozygous individual when crossing over occurs, and two different types of gametes are produced when crossing over does not occur. What does this information reveal about crossng over? O Crossing over introduces variety by producing different combinations of alleles. O Crossing over reduces the incidence of DNA and chromosomal mutations. O Crossing over introduces variety in by creating types of genes. O Crossing over maintains the count of genes and the original alleles in both chromosomes.
