Answer:

Option D, TT ´ tt

Explanation:

Allele for tallnes "T" is dominant over the recessive allele "t"

The genotype of a heterozygous tall offspring will be "Tt"

When a cross is carried out between "TT " and "tt" , the following offspring are produced -

T T

t Tt Tt

t Tt Tt

All the offspring have genotype "Tt" which is a heterogyzous allele pair.

Since "T" is dominant over "t", all the alleles would be heterozygous tall.

Thus, in order to produce 100 percent heterozygous tall offspring, the cross must be carried out between "TT" and "tt".

Option D is correct

erma4kov [3.2K]
On the 12th day the Follicle Stimulating Hormone reach its peak concentration.

 The Follicle stimulating hormone stimulates the growth of the egg-bearing follicles in the ovaries. The levels of Follicle stimulating hormone vary during the menstrual cycle and are best measured at its peak or baseline level. FSH levels level vary during the menstrual cycle, reaching their peak prior to ovulation. It is best to measure FSH on day three of the period via a blood sample which is called the baseline level. It provides the most accurate predictions of ovarian reserve.
