Bent pinky fingers are dominant to straight pinky fingers. If a heterozygous male and a female with straight fingers had children, which chart below would best represent the possibility of the genotypes of the offspring? Make a Punnett square on a piece of paper.

Well heterozygous means Pp and the female has pp so it would be 50/50.

    P    p

p Pp  pp

p Pp  pp

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.

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 : )
