Full pod shape (F) is dominant to constricted pod shape (f), yellow pod color (Y) is dominant to green pod color (y), and hairy stems (H) is dominant to hairless (h) in pea plants. The f, y& hgenes are linked and reside upon the same chromosome. A pure-breeding green plant with full pods and hairy stems is crossed with a pure-breeding yellow plant with constricted pods and hairless stems. The genotypes of the parents are:
Homework Answers
Assume that the gene coding for full pod shape if F and the gene f codes for constricted pod type. Similarly, gene Y codes for yellow colour and the gene y codes for green pod colour. Gene H codes for hairy stems and the gene h codes for hairless pods.
A pure breeding green plant with full pods and hairy stems and a pure-breeding yellow plant with constricted pods and hairless stems. Since there is no crossing over as the genes are linked, the genotypes of the parents are, FF HH yy and ff hh YY.

5. In Mendel's experiments, the pod color gene and the seed shape gene were located on different chromosomes (in other words, they were not linked. They assort independently). Green pods (G) are dominant over yellow pods (g) and tall stems (T) are dominant over dwarf stems (t). You are given two true breeding plants (homozygous at both genes). In the parental (P) generation, one parent has green pods and dwarf stems and the second parent has yellow pods and tall...

3. Yellow seeds is a dominant characteristic in pea plants. Pure breeding pea plants for yellow seeds were crossed with pure breeding pea plants for green seeds. The F1 generation all exhibited yellow seeds. An F1 plant was crossed to a green plant. Of 800 F2 plants, how many are expected to exhibit green seeds? Show work for full credit.

2) In pea plants, pod shape is controlled by a single gene with 2 alleles with the dominant allele (F) producing full pods and the recessive producing constricted pods. You cross 2 individuals with full pods and get 150 with full pods and 35 with constricted pods. Test the hypothesis that the parental genotypes were ff and Ff using a chi-square test.

A tomato plant heterozygous for stem color and fasciation (the dominant alleles linked on the same chromosome) is pollinated by a plant heterozygous for stem color and homozygous recessive for fasciation (that is nonfasciated). 29. What alleles will the sperm carry?_ What alleles will the eggs carry? 30. What are the genotypes of the progeny? What are the phenotypes of the progeny? 31.

Example Problem 2 A plant has fruits where green is dominant to blue, and hairy is dominant to waxy. The genes for color and texture are on the same chromosome, and have a recombination frequency of 14%. True breeding green, waxy plants are crossed with true breeding blue, hairy plants. The F1 is test-crossed with a blue and waxy plant. What are the expected genotypes, phenotypes, and phenotype proportions of the test-cross progeny?

In the garden pea, yellow cotyledon color (Y) is dominant to
green (y), and inflated pod shape (P) dominant to constricted (p).
A yellow cotyledon/inflated pea plant (YYPP) was crossed with a
green cotyledon/constricted (yypp) pea plant. The resulting F1
hybrid plant displayed a yellow cotyledon and inflated phenotype.
Selfing the F1 plants was performed and the F2 numbers are shown
below.
193 green, inflated
184 yellow, constricted
556 yellow, inflated
61 green, constricted
