- for any gene with a dominant allele and recessive allele a what proportions of the offspring from an AA x Aa cross are expected to be homozygous dominant, homozygous recessive and heterozygous?Human ABO blood type is controlled by the I locus and has three possible alleles. The alleles which code for type A blood (IA) and type B blood (1³) are codominant, while the allele for type O blood (i) is recessive. In a cross between a person with a genotype of lªi and a person with genotype I³i, what is the probability of having three offspring with type 0 blood? O 1/4 O 1/32 O 1/64 O 1/8 O 1/16A monohybrid cross between two pea plants producing yellow peas, resulting in an F1 phenotypic ratio of 3:1 (three yellow pea plants to one green pea plant) indicates what about the parental pea plants? one parental pea plant is homozygous dominant, and the other is homozygous recessive both parental pea plants are homozygous dominant one parental pea plant is homozygous dominant, and the other is heterozygous both parental pea plants are heterozygous one parental pea plant is homozygous recessive, and the other is heterozygous
- An allelic series determines coat color in rabbits: C (full color), c (chinchilla, gray color), c` (Himalayan, white with black extremities), and c (albino, all white). The C allele is dominant over all others, c is dominant over over c, and c is recessive to all other alleles. This dominance hierarchy can be summarized as C > c the table are crossed and produce the progeny shown. h Cc X c c Parents full color × albino Himalayan x albino full color x albino full color × Himalayan full color X full color Cross A B C D 50% full color, 25% Himalayan, 25% albino 75% full color, 25% albino E Match the parental genotypes to the letter corresponding to the appropriate cross listed in the table. A CC x cc VIV B Cc x Cc Offspring 50% full color, 50% albino 50% Himalayan, 50% albino 50% full color, 50% chinchilla Cc x cc C Answer Bank h с с X сс ch Cc xcc D h h с с X сс and c, c is dominant > c> c. The rabbits in ETrue False One heritable factors such as recessive form could mask the presence of the alternate allele which is in dominant form A Punnett square is used to predict the genotype and the phenotype of an offspring after a genetic cross. Mendel's law of dominance states that "when parents with pure and contrasting traits are crossed together, only one form of trait appears in the next generation." A homozygous individual could have a "Ee" as genotype DNA has a ribose sugar.

- In a Monohybrid Cross using corn (or pea plants), the Parent generation consists of ONLY dominant phenotypes recessive phenotypes heterozygous genotypes homozygous genotypesWhat proportion of the F2 individuals would you expect to be homozygous following a dihybrid cross? (A homozygote for two separate genes may be homozygous dominant for both genes, or homozygous recessive for both genes, or homozygous dominant for one gene and homozygous recessive for the other gene.) One half One third One quarter One eighth One sixteenthIn a cross of AABbCCddEe x AaBbCcDdEe, assume that capital letters are dominant. What proportion of the offspring will show the dominant phenotype for A, B, and C and the recessive phenotype for D and E? O 3/32 O 9/64 O 9/32 O 3/64 O 3/8
- If a homozygous tall pea plant is crossed with a homozygous shortpea plant, what are the possible genotype and phenotype of theoffspring? Legend: T- tall pea plant t- short pea plant Genotypes of the parents: TT x tt Question to answer ff: 1. What is the genotypic ratio? 2. What are the possible phenotypes of the offspring? 3. What is the phenotypic ratio?Which of the following statements are true regarding the F2 offspring of a mapping cross for three genes on the same chromosome? Recombinant allelic combinations will occur less frequently when genes are further apart. assuming all three genes are genetically linked, the most common classes of F2 offspring will be those containing parental allelic combinations the recombination rate calculated between any pair of genes will never exceed 50% F2 offspring will tend to inherit all dominant or all recessive alleles from the triheterozygous parent the alleles bf each gene willassort independently making parental and recombinant allelic combinations equally likely among the F2. double recombinant offspring will be the rarest classConsider the following cross examining four gene in two parental lines: Parent 1: A/a; B/b; D/d; e/e Parent 2: a/a; b/b; d/d; E/e Assuming independent assortment for the four genes, what fraction of progeny will have the same genotype as that of parent 2?
