What is the name for the situation where a single genetic locus influences multiple traits? Group of answer choices Pleiotropy Complete dominance Epistasis Variation
Eye Color is a trait that involves a number of genes. To simplify our example, we can break down the traitinto two phenotypes: dark color and light color eyes. Dark coloration is considered dominant, or isexpressed in a heterozygous condition (when the alleles are different).Q: If you have one light eyed parent and one parent that is homozygous for dark eye color, what are thepotential eye colors of their offspring (young)? To start, what do the Parents’ alleles look like? What istheir Genotype? (Remember, you pick which letter you want to use)Light eye colored parent:Dark eye colored parent:One of the things Mendel designed was a way to provide information about how the genes are passed onfrom parent to offspring. He designed something called a Punnett Square. This square places the parents’alleles outside the box, then uses those alleles to fill in the squares.Let’s start with a reminder of what we know about the parents: Parent Phenotype(appearance) Genotype(alleles) 1 2
All of the following statements aboutinheritance are true, except one. Which one of the following statements is INCORRECT ? O All genes have two alleles: one dominant and one recessive. Some phenotypes arise from the interaction of more than one gene. O Incomplete dominance is when heterozygotes express a phenotype that appears to be a blend between the phenotypes of homozygotes. O Even If you know the genotypes of both parents, you cannot always know with certainty the genotype their child will have.
A human disease example in which a dominant allele that is lethal in homozygous state is Huntington’s. A person that is heterozygous for Huntington’s disease and a normal individual had four children together. What is your expected outcome for the surviving children (ratio-wise for the genotype)? What is the percentage of the children that are expected to survive? Draw a punnett square to support your answer provide full explanation pls!
What is a dimorphism? A trait with two distinct forms originating from the interaction of two alleles of a single gene A trait with three or more distinct forms linked to multiple alleles of a single gene A trait consisting of a continuous spectrum of forms influenced by the interaction of multiple genes and multiple alleles

What inheritance pattern results from alleles with incomplete dominance? The recessive phenotype skips a generation The recessive phenotype is sex linked There is a 3rd phenotype, often and intermediate value between the other 2 extremes There is a range of phenotypes such that the trait appears along a spectrum rather than "either or"
In humans, "unattached" earlobes are dominant over "attached" earlobes. "Widows peak" hairline is dominant over "non-widows peak" hairline. Use E and e for the earlobe phenotype alleles, and W and w for the hairline phenotype alleles. A female and a male, both with genotype EeWw have a child. What is the probability it will be a boy, and have attached earlobes and a widows peak hairline?

Mendel's principle of segregation [Select] [Select] demonstrates why a pea plant can be tall with round seeds or short with round seeds * Previous demonstrates that offspring get one copy of each chromosome from each parent demonstrates that the inheritance of one trait can affect the inheritance of another trait. even when they're on different chromosomes demonstrates that when populations are segregated they are more likely to evolve quickly
If a gene shows classic dominance (one allele is dominant, one is allele is recessive), what is the phenotype of a heterozygote? O Recessive phenotype O Unable to determine without more information Mixed phenotype O Dominant phenotype
