Which of the following is not an example of a wild-type allele?a. Yellow-flowered elderflower orchidb. Red-flowered elderflower orchidc. A gray elephantd. An albino (white) elephant

In the Pea plants studied by Mendel, green pod colour is dominant over yellow pod colour. You have grown the same species in your garden and the plant is producing only green pods. You were guaranteed by the garden store that it was homozygous (pure-breeding) but you are not completely sure. Show how you can find out.

You have a pure breeding line of tall corn and a purebreeding line of short corn.  When you cross them what do you expect the phenotype of the F1 to be? Group of answer choices A. impossible to tell with the information given B. all medium height C. 3/4 tall and 1/4 short D. all short E. all tall

Suppose that a Mendel's dihybrid cross between two double heterogotes (AaBb  x AaBb) gave you the phenotypic ratio of 15:1, assuming that the dominant allele is completely dominant over the recessive allele. Which of the following is CORRECT?     A. The A_B_ and aabb have the same phenotype. (_ means either the dominant allele or recessive allele)   B. The aaB_ and aabb have the same phenotype. (_ means either the dominant allele or recessive allele)   C. The aaB_ and A_bb have the same phenotype. (_ means either the dominant allele or recessive allele)   D. All of the above.

What does a Punnett square tell you?   a.The inheritance pattern for a pair of alleles   b.The phenotype probabilities of offspring for a given cross   c.The number of offspring who will have a particular genotype for a given cross   d.The genotype probabilities of offspring for a given cross 2.What would be the most likely karyotype for somebody described as “hemizygous positive for a Y-linked trait”?   a.Y+ Y+   b.X Y+   c.X+ Y+   d.X+ Y- 3.X-linked ichthyosis is an X-linked recessive trait that manifests in part as dry, scaly skin (“ichthy-” = fish or fish like). Suppose a couple are considering having a child together. Parent A is heterozygous for the ichthyosis allele while Parent B is hemizygous negative for the ichthyosis allele. What is the probability their child would be unafflicted with ichthyosis but be a carrier of the ichthyosis-causing allele?   a.0%   b.25%   c.50%   d.75%   e.100% 4.If somebody has the phenotype of…

It would be nice if you can give me some explanation please Number 6

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
