the gene that controls scale shine in fish has two alleles. very shiny (S) and dull (s). Fish that are heterozygous for this gene have slightly shiny scales.
in humans, the gene controlling red-green color vision is located on X-chromosome.
There are three alleles of the gene that controls blood type IA , IB, and i
In caterpillars, there are two genes that control the phenotype of hairs on the body. the hair gene controls whether the body is hair (H) or hairless (s). the length gene controls whether the hairs are long (L) or short (l)
Match them with these options (note some options are not used)
Mutiple allels
Epistasis
Linked genes
Sex-linked genes
incomplete dominance
co-dominance
1.the gene that controls scale shine in fish has two alleles is an example of multiple alleles.
2.in humans, the gene controlling red-green color vision is located on X-chromosome is an example of sex linked genes. This red–green colour blindness is X-linked, as the genes for both M and L opsins are on the X chromosome.
3. three alleles of the gene that controls blood type IA , IB, and i is an example of both multiple alleles and co dominance as It is governed by three alleles namely IA, IB and i. IA and IB show codominance while allele "i" is recessive to both IA and IB.
4. In caterpillars, there are two genes that control the phenotype of hairs on the body. is an example of epistatsis

46. (7 points) Vanessa has obtained two true-breeding strains of
mice, each homozygous for an
independently discovered recessive mutation that prevents the
formation of hair on the body.
One of the mutant strains is called naked, and the other mutation
strain is called hairless. To
determine whether the two mutations are simply alleles for the same
gene, Vanessa crosses
naked and hairless mice with each other (cross 1). All the
offspring are phenotypically wild-
type.
A) What is the most...

5. Fur colour in mice is a single gene trait controled by two alleles. In a population of 75 mice, 21 are homozygous dominant, 37 are heterozygous dominant, and 17 are homozygous recessive. What is the frequency of the dominant allele in the population? Show all work and record your answer as a value between O and 1 rounded to two decimal places 6. The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the...
