Answer:
Two locus
Explanation:
Let assume the gene for white (1st locus) be W i.e. ww = recessive
here, Let the alleles for the 2nd locus be B and b.
White: W_B_, W_bb
Black&White: wwB_
Black: wwbb
This is dominant epistasis. In dominant epistasis, where the dominant allele of the 1st locus (W) masks or hide the expression of the 2nd locus. When the two alleles in the 1st locus are recessive (ww), the alleles in the 2nd locus can be expressed(B and b).
Answer:
Fruit Flies, long wings (L) are dominant to short wings (l) show the results crossing a heterozygous with a long wing fly with a short wing fly What are the possible genotypes and phenotypes for this offspring?
Ll x Ll= LL, Li, Li and ii
2 homozygous (one is long wing fly and the other is short wing fly) and 2 dominant heterozygous
the genotype is 3:1 while the phenotype reflects 3 dominant long wing fly and 1 short wing fly
Explanation:
A direct observation usually refers to observing a behavior and knowing exactly what is happening. For example, if I see a pigeon peck at some bread, I have observed it pecking. With direct observation, I cannot assume it is eating, that it is hungry, that it has any intention whatsoever. All I know is that it pecks.
Answer: The correct answer is -
d) a dominant trait that depends on the presence of only one of many dominant alleles.
Glaucoma is an autosomal dominant trait, meaning that presence of single copy of the defective gene is enough to cause the disease.
It corresponds to a group of diseases, which cause damage in the optic nerve, leading to loss of vision and if not treated, it ultimately leads to blindness.
Thus, option D) is the right answer.
