Why is this research on the zebrafish golden gene important for understanding human biology?
Why is this research on the zebrafish golden gene important for understanding human biology? This research revealed that the gene SLC24A5 influences production of the pigment melanin.
What can zebrafish tell us about human skin color answers?
ANSWER KEY An acceptable answer would be that the melanin color in the golden zebrafish melanosomes looks like the melanin from the woman with light skin. 3. The images in Figure 2 show that the size and number of melanosomes, and the amount of melanin, are different in people with different skin colors.
What is the best explanation for the curve’s shape?
What is the best explanation for the curve’s shape? Equal numbers of light-skin and dark-skin alleles result in a majority of the offspring having intermediate phenotypes.
What is the genotype of the parent with orange eyes and white skin?
What is the genotype of the parent with orange eyes and white skin? (Note: orange eyes are recessive.) This result of the cross indicates that both orange eyes and white skin are recessive.
Is an inherited feature that varies from individual to individual?
CHARACTER is an inherited feature that varies from individual to individual. Genetic cross involving parents that differ in a single character is called a MONOHYBRID CROSS. Most human genes come in alternate versions called ALLELES. Imagine a particular trait that is determined by a single gene.
What is an allele see Concept 14.1 page?
What is an allele? See Concept 14.1 (Page 271) the recessive form of a gene. a type of chromosome. an alternative version of a gene.
What happens when you cross two heterozygous parents?
If both parents are heterozygous (Ww), there is a 75% chance that any one of their offspring will have a widow’s peak (see figure). A Punnett square can be used to determine all possible genotypic combinations in the parents. A pedigree that depicts a dominantly inherited trait has a few key distinctions.
What is the probability of having a carrier child?
Autosomal recessive inheritance: Two unaffected people who each carry one copy of the mutated gene for an autosomal recessive disorder (carriers) have a 25 percent chance with each pregnancy of having a child affected by the disorder
