OL 126 Lab 2 (2021) X int: To calculate the allele frequencies, you must keep in mind that each ndividual is diploid (i.e. it contains two leles). If the individual is homozygous, hen it will have two copies of the same llele. If the individual is heterozygous, then it will have two different alleles mat blend together to produce another color. Count up the number of each allele and then divide it by the total number of alleles in the population. 15. What are the frequencies of the three alleles at generation=0? Enter the frequency as a decimal (ex. 0.35). Round to two decimal points.

A1) The allele for widows peak (H) is dominant for the allele for no widows peak (h). At a different gene locus, the allele for hitchhikers thumb (D) is dominant to the allele for non-hitchhikers thumb (d). A man is heterozygoous for the traits and marries a woman who has no widows peak and is heterozygous for hitchhikers thumb. What fraction of this couples children should have a widow's peak and a hitchhiker's thumb? 3/8 1/4 1/2 3/4 0 A2)The allele for widows peak (H) is dominant for the allele for no widows peak (h).

ddTtBbqqAA X ddttBbQqaa   Based on the cross provided what is the probability of producing an individual that is dominant for B & A and recessive for D, T and Q?

Which of the Pedigree Diagrams below is most likely to show a family with Becker muscular dystrophy?

11:34 Make the following Punnett square. RrYYTT x rrYytt 8*8 or 64 squares. Use a blank sheet as needed. What is the phenotypic ratio of the offspring? Your gametes: 1-3-5; 1-3-6; 1-4-5; 1-4-6; 2-3-5; 2-3-6; 2-4-5; 2-4-6;

1 1 11 Q4 - How many individuals had the genotype Nn ? How many were N_? Q5 Using the Punnett square below predict the probability of the grandparents having albino children.

R d 4. (3) D R and D are linked; the distance between R and D is 10 cM. G is unlinked. Now, you test cross this individual. a) (1) What % of the progeny of the test cross will be dominant for both R and D (ignore G)? b) Now, using all 3 genes, figure out the % of each gamete and they should all add up to 100%. I did one for you (see below). Make sure you know how to do a problem like this. These gametes are: RDG Rdg rDG RdG 22.5% rDg RDg rdG
