Answer:
The correct answer is - In F2 generation we should get a 3:1 ratio of phenotypes. 3 curly dominant, 1 wild type recessive.
Explanation:
In the given case, the cross between pure-bred wild-type flies with pure-bred mutant (curly-winged) flies and it is found that in F1 generation all offsprings are curly wings which means curly wings are dominant over wild-type.
let assume w gene is responsible for wild type and W gene is responsible for the curly wings which is dominant over wild type
W W
w Ww Ww
w Ww Ww
now on self crossing
W w
W Ww Ww
w Ww ww
In f2 generation there are 75% chances of the curly wing and 25% chances of wild type or the ratio of phenotype would be 3:1
Answer:
is a result of the absence of macrophages or B cells.
Explanation:
Severe combined immunodeficiency (SCID) results due to the absence of macrophages or B cells that is responsible for the immunity of our body. Severe combined immunodeficiency (SCID) is an inherited immunodeficiency disease (PIDD) that presents in infancy results in a weak immune system that is unable to fight against even mild infections so due the absence of macrophages or B cells, the body is vulnerable to diseases.
