El concepto de flujo de genes se demuestra cuando una vaca es expulsada de su rebaño, se une a otra manada y se reproduce. Cuando la vaca contribuye al acervo genético del nuevo rebaño, ¿cuál de estos es más probable que aumente? * 10 puntos A. Selección natural B. Variación genética C. Adecuación ambiental D. Mutaciones reproductivas

Question in English:

The concept of gene flow is demonstrated when a cow is expelled from her herd, joins another herd, and reproduces. When the cow contributes to the gene pool of the new herd, which of these is most likely to increase?

A. Natural selection

B. Genetic variation

C. Environmental suitability

D. Reproductive mutations

B. Genetic variation/Variación genética

Explanation:

When an organism from one population enters a new population that does not normally mix, it brings with it its own unique genetic variation.  

Its new alleles are introduced into the new population when the cow breeds, enhancing the amount of gene variation in the new herd. This is how gene flow increases variation

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )

true is the
