A plant with red flowers is crossed with a plant with white flowers and the resulting offspring have pink flowers. What type of inheritance pattern does this describe? If two plants with pink flowers are crossed, what will be the resulting phenotypes and in what ratio?
. In pea plants, seed shape and seed color are controlled by genes located on different chromosomes. Seeds may be round (R) or wrinkled (r), with the allele for round seeds being dominant. Alleles for seed color are yellow and green, with the green allele (y) recessive to the yellow (Y) allele. If you cross an individual that is homozygous round and yellow with an individual that is homozygous for wrinkled and green, what is the genotype of the F1 individuals?
Consult Figure 3. This pedigree illustrates the inheritance of Charcot Marie Tooth disease, which is characterized by disorders of the nervous system (OMIM). What is the probability that that next child of the couple marked with an arrow will have Charcot Marie Tooth disease?
A plant with red flowers is crossed with a plant with white flowers and the resulting offspring have pink flowers. What type of inheritance pattern does this describe? If two plants with pink flowers are crossed, what will be the resulting phenotypes and in what ratio? Show punnet squares if needed
In certain cactus, prickly spines can be two-pronged or one-pronged. If a homozygous one-pronged cactus is crossed with a homozygous two-pronged cactus, the F1 generation has a mixture of spines (some are two-pronged, some are one-pronged). a. What are the genotypes of the parents and F1s?b. What mode of inheritance is exhibited? c. If the F1s were crossed, what proportion of the F2s will have genotypes like their parents?
Many of the color varieties of summer squash are determined by two different interacting genes A and B: AA or Aa gives white colored squash, aaBB or aaBb gives yellow squash, and aabb produces green squash. A plant producing white squash is self-crossed. Three fourths of the offspring produces white squash; one fourth produces green squash. What is the genotype of the parent plant producing white squash?
In a cross involving polygenic inheritance, three (3) gene pairs control plant height. The shortest andtallest plants are 12 cm and 24 cm, respectively. What height should all F1s display if the shortest andtallest plants were crossed, assuming environmental factors are the same?
In horses, coat color comes in many varieties. If a brown horse is crossed with a white horse, the offspring are palominos (brown and white manes and tails). Name the type of inheritance. If a palomino horse is crossed with a white horse, what will the phenotype ratio of the F1 be?
Minaj flowers have 3 petal colours: yellow, red and orange. If a red flower is crossed with a yellow, what is the percent chance of the offspring having yellow flowers? and what is the pattern of inheritance?
The following pedigree shows the pattern of inheritance of red-green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in black. What is the chance that a son of the third-generation female indicated by the arrow will be color blind if the father is not color blind? If he is color blind?
In pea plants, seed shape and seed color are controlled by genes located on different chromosomes. Seeds may be round (R) or wrinkled (r), with the allele for round seeds being dominant. Alleles for seed color are yellow and green, with the green allele (y) recessive to the yellow (Y) allele. If you cross an individual that is homozygous round and yellow with an individual that is homozygous for wrinkled and green, what is the genotype of the F1 individuals? Set up a Punnett square for the dihybrid cross.
1. A What would be the genotype(s) and phenotype(s) of the offspring when a heterozygous corn plant is bred with a homozygous plant with purple kernels? Show your work in a Punnett square and explain why you would get the proposed offspring (demonstrate your understanding of inheritance in terms of genotype and phenotype). 1. B What would be the genotype(s) and phenotype(s) of the offspring when a heterozygous corn plant is bred with another heterozygous corn plant? Show your "reasoning" with a Punnett square.
