The dominant C allele of a gene that controls color in corn produces kernels with color; plants homozygous for a recessive c allele of this gene have colorless or white kernels. What kinds of gametes, and in what proportions, would be produced by the plants in the following crosses? What seed color, and in what proportions, would be expected in the offspring of the crosses? a. CCCc b. Cccc c. CcCc
In cats, the genotype AA produces tabby fur color; Aa is also a tabby, and aa is black. Another gene at a different locus is epistatic to the gene for fur color. When present in its dominant W form (WW or Ww), this gene blocks the formation of fur color and all the offspring are white; ww individuals develop normal fur color. What fur colors, and in what proportions, would you expect from the cross AaWw Aa Ww?
Several alleles affect traits of roses, such as plant form and bud shape. Alleles of one gene govern whether a plant will be a climber (dominant) or shrubby (recessive). All F1 offspring from a cross between a true-breeding climber and a shrubby plant are climbers. If an F1 plant is crossed with a shrubby plant, about 50 percent of the offspring will be shrubby; 50 percent will be climbers. Using symbols A and a for the dominant and recessive alleles, make a Punnett- square diagram of the expected genotypes and phenotypes the cross between the F1 offspring and the shrubby plant.
Two pairs of traits are segregating in a cross. Two parents produce 156 progeny that fall into 4 phenotypes. The numbers of offspring in the 4 phenotypes are 89, 31, 28, and 8. What are the genotypes of the two parents?
A heterozygous individual has a _______ for a trait being studied. a. pair of identical alleles b. pair of nonidentical alleles c. haploid condition, in genetic terms
A true-breeding rabbit with agouti (mottled, grayish brown) fur crossed with a true-breeding rabbit with chinchilla (silver) fur produces all agouti offspring. A true-breeding chinchilla rabbit crossed with a true-breeding Himalayan rabbit (white fur with pigmented nose, ears, tail, and legs) produces all chinchilla offspring. A true-breeding Himalayan rabbit crossed with a true-breeding albino rabbit produces all Himalayan offspring. Explain the inheritance of the fur colors.
1. Hereditary deafness in dalmations (d) is a recessive trait. What percentage of the progeny of crossing DD × Dd will be expected to be a carrier of the deafness allele, but not deaf? (enter a number only) 2.In snapdragons, a flowering plant, red (R) flower colour is dominant to white (r). The heterozygous condition results in pink flower colour. If a two pink flowered snapdragons are crossed, what is the resulting phenotype ratio? Select one: a.2:2 b.1:1:1:1 c.1:2:1 d.3:1 e. (all will be the same)
7. In rabbits, a locus involved in the control of coat colour may be occupied by any of fouralleles: Full colour (C), Sepia (ck), Cream (cd), or Albino (ca). A geneticist counted the numberof Full colour (C), Sepia (ck), Cream (cd) and Albino coat offspring resulting after crossesbetween Sepia (ck) and Cream (cd) coloured coated parents. The results were as follows.• Full colour (C): 152• Sepia (ck): 53• Cream (cd): 39• Albino (ca): 6Mendelian inheritance of this trait predicts that the ratio of Full colour (C) to Sepia (ck) to Cream(cd) to Albino (ca) should be 9:3:3:1. Do the experimental results support this mode ofinheritance?

1-Show the results of a dihybrid cross for the F1 and F2 generation between P generation of a pea plant that is homozygous dominant for purple flower and yellow pea seed with another pea plant that is homozygous recessive for white flower and green pea seed. Clearly show the cross indicating BOTH genotype and phenotype for each generation. How many offspring in the F2 generation will have these phenotypes? 2-What is the probability of a woman who is a carrier for the blood disease hemophilia producing a son with hemophilia if she marries a man who does not have hemophilia? What is the probability of her daughters having hemophilia? Explain why the probability of getting this disease is different for sons versus daughters in this case. Your work should clearly indicated sex, genotype and phenotype (carrier or affected).
