Consider the following case of blending inheritance. A population of plants starts out with an equal number of individuals of heights 40 and 60 cm. The parents mate randomly, and the height of an offspring is exactly equal to the average height of its parents. Find all the ways that the heights of the grandparents average to exactly 50 cm.

Consider the following case of blending inheritance. A population of plants starts out with an equal number of individuals of heights 40 and 60 cm. The parents mate randomly, and the height of an offspring is exactly equal to the average height of its parents. Find the probability of each of the possible matings of the offspring. Out of 100 plants, about how many would have height 50 cm?
Consider the following case of blending inheritance. A population of plants starts out with an equal number of individuals of heights 40 and 60 cm. The parents mate randomly, and the height of an offspring is exactly equal to the average height of its parents. What is the probability that a 60-cm tall plant mates with a 60-cm tall plant, and the probability that a 40-cm tall plant mates with a 60-cm tall plant?
Suppose you do a cross between two parents who are both heterozygous for two traits, such as petal shape (narrow or wide, narrow is dominant) and flower color (red or white, red is dominant). If there are 160 offspring, how many would you expect to have wide petals with red flowers?
When traits show complete dominance, the genotype can be revealed by a test cross. In the example of tall and dwarf plants (Figure) why is it necessary to use the dwarf parent? In general, why is it necessary to use a parent that is homozygous recessive?
The diagram below describes the relationships of genes, alleles, and loci of genetics and how a genotype manifests as a phenotype using the pea plant flower as an example. In this case, the genotype is heterozygous, meaning that the plant carries two different alleles of the gene. Think of a scenario where you have a pea plant that is homozygous recessive in flower color. Determine the phenotype of the flower color for this plant and describe how the phenotype is derived based on the information provided in the below diagram. Make sure to include the following terms, gene, allele, locus, enzyme, and gene expression, in your discussion.
Imagine that a plant with red flowers is bred to one with white flowers and when they make fruits, the seeds are collected and grown into new plants. The new plants, when old enough, have only pink flowers. Which plants are the parental generation? Which are the first filial generation? If the pink-flowered plants are interbred with each other and the resulting seeds planted, what would that generation be called?
Describe one of the reasons that made the garden pea an excellent choice of model system for studying inheritance.
Use a Punnett square to predict the offspring in a cross between a dwarf pea plant (homozygous recessive) and a tall pea plant (heterozygous). What is the phenotypic ratio of the offspring?
In his work on pea plants, Mendel found that plant height was inherited independently of the type or color of the seed coat. This finding: Group of answer choices Explains gene linkage. Demonstrates the Law of Independent Assortment. Demonstrates the Law of Dominance and Recessiveness. Applies only to genes on the same chromosome.
A mating between Abyssinian and blotched tabbies yielded a black kitten and several Abyssinians. What were the most likely genotypes of the parents? Show two alleles of the A and T genes for both parents and state which parent is which.
What data show that "Blending" between the phenotypes of two parents is not a correct view of inheritance? Because offspring can resemble one or both parents in some regard Because offspring might be intermediate in phenotype between each parent Because blending would require DNA from each parent to work Some traits skip a generation and then return
Imagine you cross two closely related plant varieties: Maize and teosinte. You hypothesize that different alleles at just 5 genes are responsible for all the trait differences between the two plants. You take two inbred parent lines and cross them together to produce an F1 and then cross two F1 individuals together to produce F2 offspring. What proportion of the offspring do you expect to look exactly like each of the parent lines if your hypothesis is correct? Please show work using punnet squares.
