D In fava bean plant the seed color can be coded by two alleles, green (G) which is dominant and purple (g) which is recessive. A gardening hobbyist performed a cross between 2 true-breeding lines P1 and P2 that respectively have green and purple seeds. Answer the following questions in regard to the hobbyist experiment. 1) What are the genotypes of the parental lines A and B? what are the genotypes of the gametes of each parent? 2)What is the phenotype and genotype of the F1 generation of the cross? 3) What are the proportions of the genotypes of the F2 generation? 4)What are the proportions of the phenotypes of the F2 generation?

Imagine that you are performing a cross involving seed texture in garden pea plants. You cross true-breeding round and wrinkled parents to obtain F1 offspring. Which of the following experimental results in terms of numbers of plants are closest to what you expect in the F2 progeny? a. 8lOroundseeds b. 8lOwrinkledseeds c. 405:395 round seeds:wrinkled seeds d. 610:190 round seeds:wrinkled seeds
In sweet pea plant, an allele for purple flowers (P) is dominant when paired with a recessive allele for red flowers (p). An allele for long pollen grains (L) is dominant when paired with a recessive allele for round pollen grain (l). Bateson and Punnett crossed a plant having purple flowers/long pollen grains with one having white/flowers/round pollen grains. All F1 offspring had purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple flowers/round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?
More Crosses with Pea Plants: The Principle of Independent Assortment Consider the following cross: P1: AABBCCDDEE aabbccddee F1: AaBbCcDdEe (self-cross to get F2) What is the chance of getting an AaBBccDdee individual in the F2 generation?
Two plants in a cross were each heterozygous for two gene pairs (AB/ab) whose loci are linked and 10 map units (mu) apart. (Recall that 1 mu is equal to 1% recombination between two genes.) Assuming that crossing over occurs during the formation of both male and female gametes and that the A and B alleles are dominant, determine the phenotypic ratio of their offspring. Part D If the two genes are 15 mu apart and the plant is (Ab/aB), what proportion of gametes from a signal plant will be ab? Part E What proportion of the offspring of two plants ( both (Ab/aB)) will be A_B_ if the genes are 15 mu apart? Part F What proportion of the offspring of two plants ( both (Ab/aB)) will be A_bb if the genes are 15 mu apart? Part G What proportion of the offspring of two plants ( both (Ab/aB)) will be aaB_ if the genes are 15 mu apart? Part H What proportion of the offspring of two plants ( both (Ab/aB)) will be aabb if the genes are 15 mu apart? How would I solve these?
Two plants in a cross were each heterozygous for two gene pairs (AB /ab) whose loci are linked and 30 map units (mu) apart. (Recall that 1 mu is equal to 1% recombination between two genes.) Assuming that crossing over occurs during the formation of both male and female gametes and that the A and B alleles are dominant, determine the phenotypic ratio of their offspring. Part E: What proportion of the offspring of two plants (both (AB/ab ) will be A - B- if the genes are 30 mu apart?

In corn, a triple heterozygote was obtained carrying themutant alleles s (shrunken), w (white aleurone), andy (waxy endosperm), all paired with their normal wildtype alleles. This triple heterozygote was testcrossed, andthe progeny contained 116 shrunken, white; 4 fully wildtype; 2538 shrunken; 601 shrunken, waxy; 626 white;2708 white, waxy; 2 shrunken, white, waxy; and 113 waxy.a. Determine if any of these three loci are linked and,if so, show map distances.b. Show the allele arrangement on the chromosomesof the triple heterozygote used in the testcross.c. Calculate interference, if appropriate.
REad and analyzed the following genetic problem. Show complete solution (Genotypes of P, Punnet Square and GR,PR). 1. In the garden peas, green pod color is dominant over yellow pods. Also, round seed shape is dominant over wrinkled seed. Cross fertilization was done between a pea that is homozygous dominant for pod color with heterozygous round shape and another pea that is heterozygous for both pod color and seed shape. Determine the genotypic and phenotypic ratio of teh offspring.

Monohybrid Crosses and Punnett Squares Punnett squares are diagrams that can be used to predict the offspring that could result from combination of the gametes produced by two parents (or an organism that can self-) The from the gametes of one parent (eg, eggs) are placed on one axis of the Punnett square while alleles from the gametes of the other parent (egsperm) are placed on the other 1.

PURPLE VESTIGIAL DIHYBRID TESTCROSS In the parental generation, you mate a pure-breeding wild-type female (put/put.vg+/vg+) with a pure-breeding purple, vestigial (pu/pu;vg/vg) to produce an F1 generation that is all wild-type (put/pu;vg+/vg). Note that the F1 flies are all dihybrid. Next, you mate several F1 dihybrid females (put/pu;vg+/vg) with tester males, which are purple, vestigial (pu/pu;vg/vg). The offspring of this dihybrid testcross are: Phenotype Wild-type Purple, vestigial Vestigial Purple Genotype Tester Gamete Dihybrid Gamete Number 437 417 77 59 Copy the table into your notes and derive the dihybrid gametes following the example in the first section. The columns in blue (phenotypes and numbers of offspring) are what you can see and count. The genotypes of the testcross offspring (orange) must be deduced from the phenotypes and knowing that the tester contributed pu vg gametes. Finally, you can deduce the dihybrid gametes (green) by subtracting the tester gamete…
A cross is made between plants with red flowers and plants with white flowers. The seeds obtained from this cross are sown and, having adult plants, the following are found: 222 plants with pink flowers, 108 red and 90 white. How could you explain these results?1. A recessive gene that was hidden and appeared in these offspring.2. That the alleles involved in these characteristics are codominant.3. What is a cross of a dihybrid with the recessive homocyte4. That the color of pink flowers is the result of a very common mutation in ornamental plants
