Gametesmust be haploid because
genotype
one X chromosome and one Y chromosome
An egg cell
Cystic Fibrosis
the X chromosome only
the allele for colorblindness is recessive and located on the X chromosome
two gametes will unite during fertilization to create a diploid cell
two X chromosomes
The genetic make up of an organism is called
genotype
one X chromosome and one Y chromosome
An egg cell
Cystic Fibrosis
the X chromosome only
the allele for colorblindness is recessive and located on the X chromosome
two gametes will unite during fertilization to create a diploid cell
two X chromosomes
Most sex-linked genes are located on
genotype
one X chromosome and one Y chromosome
An egg cell
Cystic Fibrosis
the X chromosome only
the allele for colorblindness is recessive and located on the X chromosome
two gametes will unite during fertilization to create a diploid cell
two X chromosomes
What is an allele?
genotype
one X chromosome and one Y chromosome
An egg cell
Cystic Fibrosis
the X chromosome only
the allele for colorblindness is recessive and located on the X chromosome
two gametes will unite during fertilization to create a diploid cell
two X chromosomes
which of these disorders is recessive?
genotype
one X chromosome and one Y chromosome
An egg cell
Cystic Fibrosis
the X chromosome only
the allele for colorblindness is recessive and located on the X chromosome
two gametes will unite during fertilization to create a diploid cell
two X chromosomes
Colorblindness is more common in males than female because
genotype
one X chromosome and one Y chromosome
An egg cell
Cystic Fibrosis
the X chromosome only
the allele for colorblindness is recessive and located on the X chromosome
two gametes will unite during fertilization to create a diploid cell
two X chromosomes
In humans, a male has
genotype
one X chromosome and one Y chromosome
An egg cell
Cystic Fibrosis
the X chromosome only
the allele for colorblindness is recessive and located on the X chromosome
two gametes will unite during fertilization to create a diploid cell
two X chromosomes
Human female produce egg cells that have
genotype
one X chromosome and one Y chromosome
An egg cell
Cystic Fibrosis
the X chromosome only
