When two parents heterozygous for genes for curly hair are crossed, what percent of their offspring would have curly hair? What percent would have straight hair?
Answer:
75% curly
25% straight
Explanation:
When two parents' heterozygous for genes for curly hair are crossed, 75% of their offspring would have curly hair, while 25% of their offspring would have straight hair.
What do you mean by Heterozygous?Heterozygous may be defined as the presence of two different alleles at a particular locus. It always includes one normal allele and one mutated allele.
Here, the allele for curly hair is dominant over the allele for straight hair. So, the offspring who carry the pure dominant and heterozygous alleles for curly hair would have the phenotype of curly hair, while the offspring who carry both the recessive allele would have the phenotype of straight hair.
Therefore, when two parents' heterozygous for genes for curly hair are crossed, 75% of their offspring would have curly hair, while 25% of their offspring would have straight hair.
