In pea plants, green pods are dominant over yellow pods. Two plants with green pods are crossed. All the offspring plants are counted and pod colors recorded. It is discovered that the F1 generation consists of 123 individuals, of which, 92 have been found to have green pods and 31 were found to have yellow pods. What is the genotype of the plants in the F1 generation with yellow pods? What are the most likely genotypes of the parent plants?

Concept explainers

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.

34-35 In pea plants, green pods are dominant over yellow pods. Two plants with green pods are crossed. All the offspring plants are counted and pod colors recorded. It is discovered that the F1 generation consists of 123 individuals, of which, 92 have been found to have green pods and 31 were found to have yellow pods. What is the genotype of the plants in the F1 generation with yellow pods? What are the most likely genotypes of the parent plants?

In autotetraploid Chinese primrose (Primula sinensis L.), the gene controlling stigma color is very near the centromere of the chromosome carrying it. The allele G for green stigma is dominant to g for red stigmas. A homozygous green autotetraploid strain is crossed with a homozygous red autotetraploid strain. Each of the F1 GGgg plants would obtain 12 gametes which are 2GG, 8Gg, and 2g. How were these obtained?
Female fruit flies from a true-breeding strain with yellow body and cut wings are mated to male fruit flies from a true breeding strain that is wild type for both body color and wings.

The F1 males and females are intercrossed, and among 1000 male progeny the following is observed: 425 yellow body and cut wings 405 wild type body and wild type wings 90 yellow body and wild type wings 80 wild type body and cut wings Are these genes X-linked or autosomal?

Sunflowers with flowers 10 cm in diameter are crossed with a plant that has 20-cm flowers. The F1 plants have flowers 15 cm in diameter. In the F2 generation, 4 flowers are 10 cm in diameter and 4 are 20 cm in diameter. Between these are 5 phenotypic classes with diameters intermediate to those at the extremes. a. Assuming that the alleles that contribute to flower diameter act additively, how many genes control flower size in this strain of sunflowers? b. How much does each additive allele contribute to flower diameter? c. What size flower makes up the largest phenotypic class?
In Drosophila, a cross was made between a yellow-bodied male with vestigial wings and a wild-type (WT) female(brown body and normal wings). The F1 generation consisted of WT males and WT females. The F1 males and females were crossed, and the F2 progeny consisted of 16 yellow males with vestigial wings, 48 yellow males with WT wings, 15 brown males with vestigial wings, 49 WT males, 31 brown females with vestigial wings, and 97 WT females. Based on these results, explain the inheritance of the two genes (i.e. autosomal or sex-linked, dominant or recessive).
Two pure-breeding lines of petunia plants are crossed. Line 1 plants grow to a height of 54 cm, and Line 2 plants grow to a height of 18 cm. Petunia plant height is controlled by three genes, A, B and C. Line 1 has the genotype A₁A₁B₁B₁C₁C₁, and line 2 has the genotype A2A2B₂B₂C₂C₂. Assume that genotype alone determines plant height under ideal growth conditions and that the alleles of the three genes are additive.
