Answer:
P(purple, short) = 3/16
Explanation:
Purple flowers require genotypes Pp, pP or PP
Short pollen grains require genotype ll
The genotypes are
PPll (1/16), Ppll (1/16), pPll (1/16) for a total of 3/16
Explanation:
Homologous chromosomes are 2 physically different chromosomes that have the same genes but are not genetically identical. Sister chromatids are 2 copies of a single chromosome and so are genetically identical (they also are physically attached to one another).
1. The percent probability that the first child of the couple will have Huntington's disease is 50%
2. The percent probability that four of the seven children will have Huntington's disease is 6.25%
<h3>Genetical probabilities</h3>
The disease is autosomal dominant. Only one dominant allele is needed for the disease to be manifested.
The husband is Hh and the wife is hh.
Hh x hh
Hh Hh hh hh
Hh (affected) = 1/2
hh (unaffected) = 1/2
1. Probability that the first child of this couple will have Huntington's disease is the same as the probability of having the disease. Thus, it is 1/2 (50%)
2. Probability that four of the seven children will have Huntington's disease is the same as the probability of having the disease in 4 places.
1/2 x 1/2 x 1/2 x 1/2 = 1/16 or 6.25%

Which physiologic body functions decrease in response to certain pubertal changes?
-->> select all that apply? <--
You didn't list any choices, but here's a summary:
Growth in stature (height), musculature (esp. males), growth and development of the penis and testicles in males and vulva and vagina in females. Also growth of pubic hair in axilla, pubic and suprapubic (above genitals) areas, some facial and chest hair (males).
Also in males, larynx (voicebox) changes as to deepen their voice frequency.
More oily secretions around the pubic, suprapubic, perineal, perianal, axillae, and face. This fact is what creates acne, body odor (B.O.), and pheromones.
