If a plant that is heterozygous for both traits is allowed to self-fertilize, how many of the offspring would also be heterozygous for both traits? A) 9/16 B) 1/4 C) 3/16 D) 1/8 E) 1/16 2-5 If a plant with purple, axial flowers and green, inflated pods is heterozygous for all four genes, how many different types of gametes can it produce? A) 1 В) 4 C) 8 D) 9 E) 16 2-6 The gene L detemines hair length in rabbits. The gene B determines hair color. A rabbit with long, black hair is crossed to a rabbit with short, white hair. All the offspring have long, black hair. What are the genotypes of the parents? A) LLBB x bb В) LIBЬ * LIBЬ С) LIBЬ * 1ьЬ D) LIЬЬ x 1ВЬ E) Impossible to determine from the information given 1 2-7 A couple has four children. What is the probability that they have four boys? A) 1/2 B) 14 C) 1/8 D) 1/16 E) 1/32 2-8 Humans have a gene, T, that is involved in muscle formation of the tongue. Individuals homozygous for one allele can roll their tongues, while individuals homozygous for the other allele cannot. If both parents can roll their tongues, but their child cannot, what can be said about the mode of inheritance? A) Tongue rolling is dominant. B) Tongue rolling is recessive. C) The parents were both homozygous, but the child was heterozygous. D) Tongue rolling is dominant, and both parents were heterozygous (Tt). E) Tongue rolling is recessive, and both parents were heterozygous (T) 2-9 In the accompanying figure, the chance that individual III-5 is a heterozygous carier is 3 5 5 8 9 10 1 13 14 15 IV " י" 15 8 11 12 13 14 A) 0% B) 25% C) 50% D) 75% E) 100% 2-9 What is the probability of rolling two six-sided dice and obtaining two 4s? A) 1/6 B) 1/3 C) 1/36 D) 1/9 E) 1/12 2-10 In pet rabbits, brown coat color is autosomal recessive to black coat color. A black female rabbit gives birth to 8 black-coated and 7 brown-coated baby rabbits. What can be deduced about the genotype of the baby rabbits' father?

A couple comes into the family counseling center and wants information on genetic counseling. They are thinking of starting a family but the wife has a family history of Tay Sachs disease. Kieran is a genetic counselor who will explain the services available at the center. Kieran’s discussion will include genetic mutation, tests that may be done during pregnancy, and advances being made in genetic therapy. What information can Kieran give the couple regarding the services of the genetic counseling center?

I been having a hard time finding an article relates to gene linkage. That have these requirements: 1. Must be peer reviewed Journal article (not a review article). 2. The article must have been published not later than January 2020 or has to be present year (year: 2024)

Procedure: 1. Stick a piece of masking tape on the four 25 g coins. Make sure that the size of the tape is within the circumference of the coin. For this purpose, two of Mendel's seven characters of the pea plant will be used: height and seed color. 2. Mark one side of two coins I (tall allele) and the other side t (short allele). Similarly, mark one side of the other two coins Y (yellow allele) and the other side y (green allele). 3. Monohybrid Cross. In this part, the height character will be investigated. a. Get the two coins for height: one coin corresponds to the male and the other coin to the female. T and t are gametes for tallness and shortness, respectively. b. Place the two coins in cupped hands, shake them, and toss the coins on your desk. c. Read and record the coin combinations in your data sheet. Repeat the toss 50 times. 4. Dihybrid Cross. This time, two traits will be considered: height and seed color. a. Get all four coins, place them in cupped hands, and shake and…
