What is the probability that an offspring will have a homozygous genotype? c. What is the probability that an offspring will have a dominant phenotype? d. What is the probability that three offspring will be produced that all carry the recessive allele but do not express the recessive phenotype?
Perform the following crosses: A. If having a widow's peak is dominant to having a straight hair line. What percentage of the offspring of a heterozygote with a homozygous recessive will have a widow's peak? B. Using what you have learned, predict the phenotypes of the offspring in this cross. G = grey g= brown L = long hair A GGLL mates with a ggll. 1 = short hair

A. dihybrid cross with independent assortment; epistasis B trihybrid cross with linked chromosomes; Down syndrome C dihybrid cross with linked chromosomes; the 9:3:3:1 ratio will remain unchanged regardless of other conditions D. dihybrid cross with independent assortment; Turner syndrome E. monohybrid cross with independent assortment; epistasis
A scientist studying a species of algae, Gracilaria domingensis, discovered that its color is controlled by a single gene with two alleles. The individuals with a red or green phenotype are homozygous for the red or green alleles and the individuals with a brown phenotype are heterozygous. The scientist crosses two brown individuals. What percent of the offspring from this cross is predicted to be brown? A: 25%B: 50%C: 75%D: 100%
In cats, the gene for calico (multicolored) cats is both sex-linked and codominant. Due to a phenomenon known as dosage compensation, females that receive a B and an R gene have black and orange splotches on white Males can only be black or orange, but never calico. a. What would a calico cat’s genotype be? b. Show the cross of a female calico cat with a black male. What percentage of the kittens will be black and male? c. What percentage of the kittens will be calico and male? d. What percentage of the kittens will be calico and female? e. Show the cross of a female black cat with a male orange cat. f. What percentage of the kittens will be calico and female? What color will all the male cats be?
The chart below is showing 4 generations of a family that is affected by a hereditary disease. a. Is the disorder being tracked dominant or recessive? How do you know? b. There is only one possible genotype for person C. True or False? c. What are the possible genotypes for person A? d. What are the possible genotypes for person B?, e. If two people with the same genotypes as person C's spouse and person A's spouse had a child, what is the probability that the child will be affected by this genetic disorder? (draw a Punnett square using the correct genotypes to help you). % chance offspring will be affected % chance offspring will not be affected
In a test cross, peas of an unknown genotype are crossed with peas of a known genotype. In this example, smooth peas are the unknown and wrinkled peas are the known (rr). If half of the offspring from that cross are smooth and half are wrinkled, what is the genotype of the unknown plant? O a. Homozygous dominant: RR O b. Homozygous recessive: rr Oc. Incomplete dominance d. Heterozygous dominant: Rr CLEAR MY CHOICE
Answer the following with a short solution if needed: a. The gametes of a worm's genotype SsYy should produce what genotypes? b. A genetic cross between two F1-hybrid rose plants having yellow petals will yield what percent green-petal plants in the F2 generation? Yellow petals are dominant to green. c. Brown fur is dominant over light-colored fur. What is the phenotype of the resulting offspring if you cross a heterozygous brown fur and a light-colored fur?
Imagine that you are performing a cross involving seed color in garden pea plants. What traits would you expect to observe in the F1 offspring if you cross true-breeding parents with green seeds and yellow seeds?
