Curly hair (c) is dominant over straight hair(c). a heterozygous curly haired woman marries a homozygous straight haired man. with respect to hair.
a. write the genotypes of man and woman
man:
woman;
b. what % of the children will have curly hair

The woman's genotype is Cc (she's heterozygous)

The man's genotype is cc (he's homozygous)

If you make a punnet square it'll look like this (I hope it works out)

    C     c

c  Cc   cc

c  Cc  cc

Since curly hair (C) is dominant, any genotype with a capital C will have curly hair. This means 2/4 or 50% of children will have curly hair

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
