In humans, the allele for brown eye color (B) is dominant to blue eye color (b). If two heterozygous parents produce children, what are the following probabilities? **Note, this problem way over simplifies eye color, which is influenced by at least eight different genes. a. A total of four children, two with blue eyes and the other two with brown eyes. b. The first child has blue eyes, and the next two have brown eyes.

In the pedigree shown in Figure Q19–14, the first born in each of three generations is the only person affected by a dominant genetically inherited disease, D. your friend concludes that the first child born has a greater chance of inheriting the mutant D allele than do later children.A. According to Mendel’s laws, is this conclusion plausible?B. What is the probability of obtaining this result by chance?
In humans, the genetic disease cystic fibrosis is caused by a recessive allele (a). The normal (healthy) allele is dominant (A). What is the genotype of someone who has cystic fibrosis? What are the two different genotypes that a healthy person could have? If two people were both heterozygous for the cystic fibrosis gene, what fraction of their children would be likely to have this disease? Hint: Draw a Punnett square to figure it out.
. In four-o’clocks, the allele for red flowers is incompletely dominant to the allele for white flowers, so heterozygotes have pink flowers. What ratios of flower colors would you expect among the offspring of the following crosses: (a) pink × pink, (b) white × pink, (c) red × red, (d) red × pink, (e) white × white, and (f) red × white? If you specifically wanted to produce pink flowers, which of these crosses would be most efficient?
In humans, potential or expecting parents can be tested for the presence of the allele for the autosomal recessive cystic fibrosis. Which combination of parents are LEAST likely to produce a child with cystic fibrosis? A. 2 parents with cystic fibrosis B. 2 parents without cystic fibrosis C. 1 parent without cystic fibrosis and 1 with cystic fibrosis D. 2 parents who do not know if they have cystic fibrosis
In humans, the allele for brown eye color (B) is dominant to thatfor blue eye color (b). If two heterozygous parents produce children, what are the following probabilities? A. The first two children have blue eyes.B. A total of four children, two with blue eyes and the other twowith brown eyes.C. The first child has blue eyes, and the next two have brown
In humans, brown eyes are dominant to blue eyes, and the ability to roll your tongue is dominant to not being able to roll your tongue. If a mother who was heterozygous for eye colour and homozygous recessive for tongue rolling had a baby with a father that was heterozygous for both traits, what is the probability that their child would have blue eyes and could roll their tongue?
If you are working to solve for the relative distances between a cat's genes for fur color, where gene X has alleles X and x and gene Y has alleles Y and y that follow an autosomal dominant pattern of inheritance, which test-cross should you perform to determine a genetic map? A. XxYy x XxYy B. XXYY x xxyy C. XxYy x xxYy D. XxYy x xxyy
In humans, hair color and structure are determined by two independent pairs of genes. The dominant gene T determines dark hair color, and the recessive allele t - light hair; The dominant gene S determines the formation of curly hair, and its recessive allele t - straight hair. What kind of hair will the children have if the mother has light, straight hair, and the father has dark, curly hair (one of the pairs of traits is heterozygous for both parents)?
In mice, black color (B) is dominant to white (b). On different homologous chromosomes, a dominant allele (A) produces a band of yellow just below the tip of each hair in mice with black fur. This gives a frosted appearance known as agouti. Expression of the recessive allele (a) results in a solid coat color. If mice that are heterozygous at both locations are crossed, what is the expected phenotypic ratio of their offspring? Use the rules of probability instead of a huge Punnett square.
Given a cross between these two parents: BbCcDDEEFfGgHhjj x BbCcddEeFfGgHHjj where traits B, E, H, J exhibit Mendelian inheritance; C, and F exhibit incomplete dominance; D, and G exhibit co-dominance answer the following: What proportion of the offspring will phenotypically resemble the first parent? What proportion of the offspring will genotypically resemble the second parent? How many phenotypes can be expected from the cross?
using a Punnett square, what will the offspring look like when the parents are Bb and Bb. B = dominant black hair and b = recessive blue hair. So what percentage of the offspring will have black hair vs blue hair?
In humans, the allele for short fingers is dominant over that for long fingers. If a person with short fingers had one parent with long fingers and marries a person with long fingers, what are the chances for each biological child to have short fingers?. Show a punnet square.
