Answer:
F1 Females - all wild type
F1 Males - all wild type
F2 Females - - all wild type
F2 Males - 1/2 wild type, 1/2 vermilion
Explanation:
The wild-type allele (Xᵛ⁺) is dominant over vermilion (Xᵛ), which is a sex-linked trait.
Female flies have two X chromosomes, male flies have one X and one Y chromosome.
A homozygous wild-type female fly (Xᵛ⁺Xᵛ⁺) is mated with a vermilion male fly (XᵛY).
The female parent can only produce Xᵛ⁺ gametes.
The male parent can produce either Xᵛ or Y gametes.
When gametes from both parents fuse, the F1 offspring will have the genotypes Xᵛ⁺Xᵛ (females with wild type eyes) and Xᵛ⁺Y (males with wild type eyes).
The F1 females can produce Xᵛ⁺ and Xᵛ gametes. The F1 males can produce Xᵛ⁺ and Y gametes.
When the F1 individuals interbreed, the gametes combine to give rise to the F2 offspring. The possible combination of gametes that will give the different genotypes and phenotypes in the F2 are:
- Xᵛ⁺Xᵛ⁺ females with wild type eyes
- Xᵛ⁺ Y males with wild type eyes
- Xᵛ Xᵛ⁺ females with wild type eyes
- Xᵛ Y males with vermilion eyes
Answer:
I think the correct answer is D
Although the dolphin lives in the sea, it is not a fish - it's a mammal.
It makes the most sense if you read it aloud.
The correct answer is nephron.
<span>
The nephron consists of Bowman’s capsule ( where blood is initially filtered ) and glomerulus which is a tuft of capillaries. Bowman’s capsule and a glomerulus together form the renal corpuscle. The renal tubule extends from the capsule and it consists of proximal convoluted tubule (selective reabsorption), a loop of Henle (establishes a salt gradient) and distal convoluted tubule (selective reabsorption). </span>
Answer:
Animal Cell
Explanation:
If you search up animal cell diagram, it should come up ano there’s differnet angles of the cell to choose from but most of them come with the labels.!
