Answer:
Cold weather triggers the underfur to grow each winter.
Explanation:
this is because they would freeze in the cold water in the winter.
Similar structures that evolved independently are called analogous structures
Answer:
9/64
Explanation:
Given, AABBGG X aabbgg = AaBbGg (F1)
Resulting F1 progeny is self fertilized.
AaBbGg X AaBbGg :
If we check individual crosses:
A a
A AA Aa
a Aa aa
3/4 of the progeny will display dominant A phenotype ( AA, Aa ). Similarly,
3/4 of the progeny will display dominant B phenotype ( BB, Bb ).
G g
G GG Gg
g Gg gg
1/4 of the progeny will display recessive g phenotype (gg).
Total offspring that will display ABg phenotype =
3/4 * 3/4 * 1/4 = 9/64
Like all planets and most stars, the motion of the sun is directly related to the rotation of it's axis.
Answer:
Why can a female only pass on an X chromosome to offspring?
It is an established fact that female has XX chromosomes while male has XY chromosomes, during fertilization both male and female donate one of the pairs to form a pair of allele for the offspring. The female donate an X chromosome since the two chromosomes in her possession is XX while the male donate either of the X or Y chromosome
