Multiple choices: Question: Handedness (whether you are right or left-handed) shows a 79% concordance in monozygotic twins and a 77% concordance in dizygotic twins. Using this information, do you expect handedness to have a large genetic influence? a. No, although the concordance numbers are high, they are similar between MZ and DZ twins b. No, concordance is not 100%

The three colors that show this trait are dark blue (B), white (W), and light blue (BW). Find the following: a. Genotypic and phenotypic ratios when a dark blue butterfly is crossed with a light blue butterfly b. Genotypic and phenotypic ratios of the F, generation when dark blue and white butterflies are crossed

Track one gene: Blue bonnet flower color. Dominant allele = blue flowers, B; Recessive allele = white flowers, b Cross: heterozygous plant x homozygous recessive plant Set up and draw the Punnett square for this cross Predict % likelihood of offspring possible genotype & phenotypes B.

Incomplete Dominance: 1) On the planet Iota Geminorum IV there exists a small hairy animal known as a tribble. It comes in three colors blue, red, and purple. This trait is controlled by a single locus with incompletre dominance. A homozygous CBCB is blue, a homozygous CRCR is red, and a heterozygous CBCR is purple. a. What would be the genotypes and phenotypes of the offspring if a blue tribble were crossed with a red one? b. If the offspring in #1 were crossed what would the genotypic and phenotypic ratios be of this generation?

Which gene is dominant? Why? What is the genotype of your offspring? You then cross the offspring to each other. What ratio do you expect? Why? You count 1000 plants and look at their flowers. Your results are as follows: 740 red 260 white Does this follow a simple Mendelian inheritance pattern? Why or why not? DADT 2 MEA SUDI ND D LUT IONS
A. In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and diskshaped fruit (D) is dominant over sphere-shaped fruit (d).

/a2 = 32 Familier, d. at least one girl? 3/32 = 968 Familier In squash, fruit color is determined by one gene and fruit shape by another independently segregating gene. The white fruit allele (W) is dominant to yellow fruit allele (w) and disk shape fruit allele (D) is dominant to round-shaped fruit allele (d). A cross between a white-colored, disk-shaped squash and a white colored, round-shaped squash resulted the following offspring: 31 white, disk; 29 white, round; 9 yellow, disk; 10 yellow, round.

Brown eyes are dominant over blue eyes. In the same manner, the presence of dimples is dominant over no dimples. A man heterozygous for eye color and with no dimples is married to a blue-eyed woman who is heterozygous for dimples. What is the probability that they will have: (write the answers ONLY)1. a baby girl?2. an offspring with dimples? 3. an offspring with blue eyes?4. a brown-eyed baby boy with no dimples?
