Genetics problem: (please show work or explain)
You have freckles, dimples and a widows peak. Your significant
other has freckles and dimples but has a continuous hairline.
Freckles are dominant to no freckles
Dimples are dominant to no dimples. Widows peak is dominant to
continuous hairline.
What are all of your possible genotypes? What are all of the possible genotypes of your significant other? How can you tell?
Assuming that you are heterozygous for all three traits and your significant other is heterozygous for freckles and homozygous for dimples, what is the probability that your child will be recessive for all three traits?
What are the possible phenotypes that your children could have and the ratios (probabilities/frequencies) of each?
What is the probability that your child will have the same phenotype as you?

Observing human phenotypes and probability in genetics Name: _________________________ Purpose Reinforce concepts of simple genetics by examining the following: Genotype Phenotype Homozygous Heterozygous Dominant Recessive Materials Mirror Objectives Determine your phenotype for ten different traits. Determine your possible genotypes for the ten different traits. Evaluate your uniqueness as an individual. Part A- Determining your phenotype and genotype In part “A” you will examine your phenotype, or appearance, and will draw conclusions about your genotype, the gene combinations that determine appearance....

Question 28 (2 points) You have freckles, dimples, and a widow's peak. Your S.O. has freckles and dimples, but a continuous hairline. These three characters are located on different chromosomes and exhibit complete dominance. In other words, If the letter "w" is used to represent the hairline gene, what is the chance that your first child will have a widow's peak like you? O 0%, because your significant other is homozygous dominant for that trait 100%, beauseyour significant other is...

Human Mendelian Traits Mendelian Traits are those traits which follow Mendel's rules of only 2 possible versions of a gene(1 dominant, 1 recessive). There are only a few examples of this in humans. 1. Circle the heterozygous dominant genotypes: AA Aa aa YyYY W Re RR 2. Circle the homozygous recessive genotypes: AA Aa aa YyYY V ir Rr RR 3. Use the chart below to determine your phenotype (observable characteristic) and possible genotype(s) (a pair or pairs of alleles)....

Evaluating your phenotypes and genotypes and testing a genetic hypothesis in corn There are two activities in this write up. In the first, you will evaluate your phenotypes and genotypes and relate them to parental phenotypes and genotypes. In the second, you will test a hypothesis using a monohybrid cross in corn and carry out a Chi-squared analysis. For the write up, please copy and paste the remaining part of the Lab document into a new document, then fill in...

Human Genetics Although we humans are fantastically made, are quite complex, and our traits are often coded by many genes, some traits are coded by single gene pairs. The following table is a survey to help you determine your genotype, based on phenotype traits. Keep in mind the terms homozygous dominant (AA) will have the dominant trait, homozygous recessive (aa) will have the recessive trait, and heterozygous (Aa) will have the dominant trait. If you have the dominant trait, you...
