Determine the mode of inheritance:
Homozygous recessive die from fatal disorder, when a specific enzyme activity is absent. Heterozygous exhibit wild type phenotype but have intermediate level of gene expression resulting in 1/2 of the wild type enzyme activity when compared to Homozygous normal non-carriers. Based on the levels of gene expression ALONE, the mode of inheritance is?‐---------------
Explain how polygenic inheritance differs from inheritance that is controlled by only one gene?
Determine the type of inheritance pattern shown in the pedigree below:
Autosomal dominant
Autosomal recessive
Sex linked
Mitochondrial
A type of pattern we haven't learned (multiple alleles, polygenetic, etc.)

Hairline is controlled by gene H, where a widow's peak is dominant to a straight hairline. If a woman with curly hair and a straight hairline has a child with a man with a widow's peak and straight hair (his mom had a straight hairline), what is the chance they would have a kid that has exactly the same hair as mom? Draw the Punnett square and demonstrate the possible genotypes and phenotypes that could result from these two parents' mating.arrow_forward
- For a recessive condition, two normal heterozygous individuals have children. What is the likelihood of their children being affected by this condition? What is the likelihood of their children being carriers without the condition? What is the likelihood of their asymptomatic children being carriers? Suppose that an individual with the condition has children with a heterozygous individual, what is the likelihood of their children being carriers?arrow_forwardWhich of the following defines polygenic inheritance? An inheritance pattern in which one allele is not fully dominant over another, so the heterozygous phenotype is an intermediate blend of the two homozygous phenotypes An inheritance pattern in which the full and separate phenotypic effects of two alleles are apparent in heterozygous individuals An inheritance pattern in which a single gene affects multiple traits A pattern of inheritance in which multiple genes affect one traitarrow_forwardColor-blindness (c) is a sex-linked recessive trait, while normal color vision (C) is dominant: If two normal-visioned parents have a color-blind son, what are the parent's genotypes? ~What are the chances that their children will be color-blind?arrow_forward
- If traits are inherited together, for example if Mendel found that this pea plant always had yellow and round seeds or green and wrinkled but never yellow and wrinkled or green and round. The explanation for this must be that; a) There is one gene controlling both phenotypes Ob) The genes are located close together on the same chromosome c) The genes are located on the same chromosome d) The genes are located close together on the same chromosome or there could be one gene controlling both phenotypesarrow_forwardExplain the concept of mendal's law of inheritence?arrow_forwardIn humans, having extra fingers or toes is caused by a dominant allele (E). People with two recessive alleles have 5 fingers and toes on each hand or foot. What is the genotype of someone who has 5 fingers and toes on each hand or foot? What are the two different genotypes that someone with extra fingers or toes could have? If two people both had the normal number of fingers and toes, is there any chance that their children could inherit the allele for extra fingers and toes? Do a Punnett square and show your work. If a man who was heterozygous for this gene married someone who was homozygous for the recessive allele, what fraction of their children would you expect to have extra fingers or toes? Do a Punnett square and show your work.arrow_forward
