Scientists have observed that individuals with red hair often have freckles. Which of the following explanations is most likely responsible for this observation? A. Law of segregation B. Probability C. Genotypic ratio D. Linkage
Homework Answers
Answer:
D. Linkage
explanation: Linkage is the tendency of the two genes located on the same chromosomes to inherit together in the daughter cell. Tightly linked genes are inherited together as these genes are unable to get separated during crossing over. Hence they are expressed most oftenly together.
Hair gene for red hair is linked with genes for freckles hence they are most oftenly seen together.

Uption 4. The inheritance of hair and eye color is very complicated. Scientists have found approximately 10-20 genes responsible for determining hair and eye color in humans (sheesh - I thought a dihybrid cross with 2 genes was bad...). Although many genes are involved in producing these phenotypes, it does seem that just a few genes play a major role in determining the color of our hair and eyes. The following is a simplified, but still somewhat realistic view of...

Group of answer choices a Both of these crosses will result in the same number of genotypes and phenotypes in the F1 generation b Neither of these crosses will result in the same number of genotypes...
