Two true-breeding Triffid strains (poison stingers and no stingers) are crossed. AlL F1 progeny have poison stingers. The F1 is selfed to produce an F2. What proportion of the F2 will be true-breeding? Instructions Enter a number between 0 and 100, for example: 33 Do not enter anything else other than the number. Do not add '%' or 'percent' or anything else, just the number

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…

A tall, purple pea plant that is true-breeding is crossed with a short, white pea plant. What will the genotype(s) of their offspring be? Include a Punnett Square to justify your answer. BIU A, Paragraph + v ... Add a File Record Audio Record Video
A pureline plant of genotype Ab/Ab is crossed to another pureline plant aB/aB. The F1 hybrid is testcrossed. If both genes are closely linked with no crossover, what fraction of the progeny of this testcross will be double homozygous recessive? more than 25% O 0% O 25% less than 25% but higher than 0%
If two individuals are crossed (RrYy x RrYy), what percentage of their offspring will display the R_yy phenotype? (the _ could be either R or r, it would not affect the phenotype).
Green thorax and brown puparium is determined by the wild type alleles P+ and b+ and the receive alleles code for purple thorax and black puparium. Show how a test cross will look like in the coupling or in the repulsion configuration of these alleles. You do not have to draw the line to show a chromosome. Just write the alleles on chromosomes separated by a slash sign.
