A gene found on a sex chromosome is known as a sex-linked gene. Alleles are the different forms of a gene.
it inherited the allele that made it resisnt.
Oestrogen
The child must have inherited at least one A allele and one B allele from their parents. The child could have inherited an A allele from one parent and a B allele from the other parent, or may have inherited an AB genotype from one parent.
Huntington's Disease
inherited the allele for the trait from both parents
Sex-linked gene
dark brownn
one tall allele and one short allele
one allele from each parentThe F1 generation inherited one dominant (tall) allele from the tall parent and a recessive (short) allele from the short parent. The F1 generation were heterozygous and tall.
dominant allele
Coupling allele arrangements result in linked genes being inherited together more often, while repulsion allele arrangements result in linked genes being inherited separately more often. This affects genetic inheritance patterns by influencing the likelihood of certain traits being inherited together or separately.
If the the trait is controlled by only one allele and the allele is completely dominant then once inherited the offspring with exhibit that phenotype
