Question

УМОЛЯЮ!!!!!! РЕБЯТА, ПОМОГИТЕ, 29 БАЛЛОВ ДАЮ. У человека гены голубых глаз и коротких ресниц рецессивные. В брак вступают мужчина с длинными ресницами и голубыми, отец которого имел короткие ресницы, и кареглазая гетерозиготная женщина с короткими ресницами. Сколько различных фенотипов возможно среди детей от этого брака??????

Answer 1

Ну я думаю 16. Это всегда прокатывает сколько фанотипов людей в данном случае 4 умнажаем само на себя тоесть 4*4=16

Answer 2

Genetic Inheritance and Phenotypes

In this scenario, we are dealing with genetic inheritance and the potential phenotypes of the offspring based on the parents' genotypes.

Genetic Information: - The person has blue eye color and short eyelashes, which are both recessive traits. - The father has long eyelashes and blue eyes, with a father who had short eyelashes. - The mother is a heterozygous carrier for brown eyes and has short eyelashes.

Determining the Possible Phenotypes of the Offspring

To determine the possible phenotypes of the children, we can use Punnett squares to visualize the potential combinations of alleles from the parents.

Punnett Square for Eye Color: - The father has the genotype bb (blue eyes) and the mother is Bb (heterozygous for brown eyes). - The possible genotypes for the children are Bb and bb for eye color.

Punnett Square for Eyelash Length: - The father has the genotype LL (long eyelashes) and the mother is Ll (heterozygous for long eyelashes). - The possible genotypes for the children are LL and Ll for eyelash length.

Calculation of Possible Phenotypes

By combining the possible genotypes for eye color and eyelash length, we can determine the potential phenotypes of the children.

Possible Phenotypes: - For eye color: Brown eyes (Bb) and blue eyes (bb) - For eyelash length: Long eyelashes (LL) and short eyelashes (Ll)

Conclusion

Based on the genetic information provided, the potential phenotypes among the children from this marriage could include individuals with brown eyes and long eyelashes, brown eyes and short eyelashes, blue eyes and long eyelashes, and blue eyes and short eyelashes. Therefore, there are four different phenotypes possible among the children from this marriage.
