The allele for hitchhiker’s thumb (h) is recessive to straight thumb (H). If a man and his wife are both homozygous recessive, will any of their offspring potentially have hitchhikers thumb? What is the man’s genotype and the woman’s genotype? What is the man’s phenotype and the woman’s phenotype? What genotype(s) must the offspring have in order to have the phenotypic trait of hitchhiker’s thumb? Do a cross to determine all potential hitchhiker’s thumb genotypes and phenotypes for the offspring of this man and woman. Is it possible for any offspring of the F1 generation to have hitchhiker’s thumb?

The shaded shapes represent albino individuals. a. mother - homozygous dominant; father - homozygous dominant b. mother - heterozygous; father - homozygous recessive c. mother - homozygous recessive; father - heterozygous d. mother - heterozygous; father - heterozygous e. mother - homozygous dominant; father - homozygous recessive

If the couple marries and has a child, what is theprobability that the child will have cystic fibrosis?b. If they have four children, what is the chance that thechildren will have the precise Mendelian ratio of 3:1 fornormal:cystic fibrosis?c.

Show the complete solution including the Punnett Sq. Lina has dimples, freckles, and a widow’s peak. She is a heterozygous for all of the three traits. David, her husband also has freckles and dimples but has a continuous hairline. As freckle is known to be dominant over none, dimples are dominant over no dimples, and widow’s peak is dominant over continuous hairline, identify the Probability that their child will have three recessiveness: no freckle, no dimples, and has widow’s peak; and Probability that their child will have the same phenotype as Lina (with freckles, dimples, and widow’s peak). Legend: Ff – freckles Dd – dimples Ww – widow’s peak

Imagine a cross between a man and a woman having the following genotypes: Genotype of the Husband Genotype of the Wife Aa bb Dd Gg Hh RR Tt X Aa Bb Dd gg Hh Rr Tt Assuming that the dominant allele in each gene pair exhibits complete dominance over the recessive allele, what is the probability that this couple would have a daughter who exhibits the recessive phenotype with respect to all seven of the gene pairs?
In human beings, the gene for red‑green colorblindness (r) is sex‑linked and recessive to its allele for normal vision (R), while the gene for freckles (F) is autosomal and dominant over its allele for nonfreckled (f). A nonfreckled, normal‑visioned woman whose father was freckled and colorblind, marries a freckled, colorblind man whose mother was nonfreckled. What is the genotype of the woman's father? What is the probability that the couple's first child will be a non-freckled, normal visioned girl? What is the probability that the first two children born to the couple will be freckled and colorblind girls?
