The gene S determines the stripe color of a kind of snake.  It has two alleles which are codominant with each other: one allele (S1) causes red stripes, and the other (S2) causes white stripes.  What do you predict a heterozygous (S1S2) snake will look like? Select one: a. Assortment of pink, red, and white stripes b. All pink stripes c. No stripes d. Both red and white stripes

what is the linkage between the ct and s genes?   A. 15.7 cM   B. 32.6 cM   C. 21.3 cM   D. 43.3 cM

The color of chickens is determined by interacting loci: AA or Aa give white, aaBB or aaBb give colored, and aabb produce white. Describe the epistatic interactions occurring between these two genes: A. aa is epistatic to B_, bb and bb are epistatic to A_,aa B. A_ is epistatic to B_,bb and bb is epistatic to A_,aa C. None of the above

In pea plants, round peas (R) are dominant to wrinkled peas (r). You do a test cross between a pea plant with wrinkled peas (genotype rr) and a plant of unknown genotype that has round peas. Result: 4 plants with round peas. What is the unknown parent? Use Punnett square on homework to help answer the question. O a. Homozygous dominant O b. Heterozygous O c. Homozygous recessive O d.

Gregor Mendel developed an understanding of heredity through his experiments with pea plants. The diagram below shows a cell with 2 pairs of homologous chromosomes and genotype of AaBb. a. Identify all the possible allele combinations that could be formed if this cell undergoes meiosis. b. Identify one of Mendel's laws that is illustrated when you write out these allele combinations. EXPLAIN this law.

Human hair color ranges from black to many shades of brown to blonde. What can you correctly conclude from this information? A Human hair color is controlled by a single gene. B Human hair color is controlled by environmental factors rather than genes. C Human hair color is controlled by more than one gene. D Black hair is dominant to blonde hair. Answer is C? Can you help me to explain to me step by step?

.A) To determine if a human trait is heritable, we would best study Group of answer choices. I think it's A. Please explain your answer I'm trying to understand the material a. monozygotic twins that were raised separately, in different environments. b. monozygotic twins that have been raised under similar conditions. c.only distantly related individuals. d. all males or all females. B). To say that a trait exhibits “high heritability” is to say that a. a given set of genes has no influence on a trait. b. there is no difference in genotype between members of the population at the loci in question. c. in a given environment and population, genetic differences have a high degree of influence on the trait compared to environmental influences. d. there is no difference in character between two individuals with the same genotype in question. C). If two populations with identical genetic makeup are raised in different environments, the narrow-sense heritability of a trait of…

In swallowtail butterflies, let's pretend that the R gene codes for coloring on the forewing. The R1 allele, which codes for red color, is dominant to the R2 allele, which codes for white color. If R1 is a recessive lethal allele, what phenotypic ratio would you expect when crossing two swallowtails with red forewings?  1 red : 2 white  1 red : 3 white  3 red : 1 white  there is not enough information given to answer this question  1 red : 1 white  2 red : 1 white

Suppose a species of tulip has three alleles for the gene that codes for flower color. The CR allele produces red tulips, the CP allele produces purple tulips, and the C" allele produces white tulips. CR is dominant over CP and Cw, and CP is dominant over Cu . For each cross, determine the expected phenotype ratio of offspring flower color. CRCP X CPCW CRCW x CPCW. 1 red: 3 purple : 0 white 2 red: 0 purple : 2 white Expected phenotype ratio Answer Bank 1 red: 2 purple : 1 white 2 red: 2 purple: 0 white 1 red : 1 purple : 0 white 2 red : 1 purple : 1 white
