On the planet Kermit, in the Muppet population, there are two autosomal loci of interest. The first locus has alleles A and a, a
nd the second locus has alleles B and b. A and B are the dominant alleles at the respective loci. The loci act in an epistatic manner, identical to the way two genes interact to produce coat color in labradors. The phenotype here is muppet hair color. We have the following results: Muppet hair color as a function of two-locus genotypes
Two-locus genotype Muppet hair color
A_B_ Cookie monster blue
aaB_ Elmo red
__bb Janice blonde
If two doubly-heterozygous Cookie-monster blue-haired muppets mate, and produce 3200 children, which of the follow values most closely represents the expected number of Elmo red-haired offspring? The answer allows for random variation in hair color.
A. 1536
B. 672
C. 1242
D. 200
E. 549
The correct answer is (b.) an increase in the width of the stem. The increase in the width of the stem could be referred to as the secondary growth of the stem. Whereas the primary growth is the upward growth of the plant.
The nephrons are found at the cortex-medulla junction. There are what we call as the juxtamedullary nephrons and cortical nephrons referring to their designated locations. The juxtamedullary nephrons are involved in the creation of concentrated urine of a person.
