Write down letter designations for the alleles. Be sure to distinguish between the two traits, and be sure to consider which alleles are dominant and recessive.
Homework Answers
Let's consider a trait of flower colour.
There are two possibilities, one is Green and yellow.
Allele for Green is G and yellow is g.
G is the dominasnt one which codes for green colour and g is recessive allele which codes for yellow colour.

Consider a cross between two individuals who are heterozygous for three traits (seed shape, color, and flower color), where one allele is dominant and the other allele is recessive. What is the probability that this cross will produce an offspring with ONLY recessive phenotypes for the three traits?

People sometimes suggest that certain traits “skip a generation.” Which of the following is the best biological explanation for this saying? A A parent with two dominant alleles occasionally does not pass on an allele. B A recessive trait is sometimes masked in the F1 generation but reappears in the F2 generation. This is because of the law of segregation. C The law of independent assortment means that certain traits can be masked by a dominant allele but be phenotypically...

Human Mendelian Traits Like most complex organisms, humans possess an enormous number of genetically inherited characteristics. Some of these are Mendelian in nature, i.e., one gene with two alleles (one true dominant, one true recessive) producing two easily observed traits. You and your partner will evaluate yourselves and each other for your phenotypes, then list the appropriate genotype possibilities. If you are dominant for the trait then assume you are heterozygous unless you know your parents phenotype. 1. Rolling the...

Assume earlobe shape is controlled by a single gene with two alleles. The dominant allele generates free earlobes, while the recessive allele produces attached earlobes. A second gene on a different chromosome controls earwax consistency, where wet is dominant and dry is recessive. Bella has free earlobes with wet earwax and is heterozygous for both traits. Edward has attached earlobes with dry earwax. What is the probability that their first child will have either free earlobes or wet earwax or...

There are four alleles for the bald gene that control hair growth in an individual. A bald man who is heterozygous for the first two alleles has children with a non-bald woman who is homozygous for the third allele. All of their children are non-bald. How many gametes will the father produce? Write the allele(s). How many gametes will the mother produce? Write the allele(s). Draw the Punnett Square and the resulting offspring. Draw the relationship between alleles in the...

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)....

Of the following ideas postulated by Gregor Mendel, which one requires at least two genes to be demonstrated? a. Some alleles are recessive and are masked by dominant alleles. b. One of two alleles from each parent is randomly transmitted to offspring. c. Traits are controlled by discrete units. d. Genes assort independently in diploids. e. Traits are not determined by blending.
