It can happen when both parents are a heterozygous
Heterozygous means inheriting different genes from your parents. That is a heterozygous trait, not a homozygous one.
both parents could be A heterozygous or one A heterozygous and the other O
AA could be either homozygous or heterozygous, depending on whether the individual inherited the same allele (A) from both parents (homozygous) or different alleles (Aa) from each parent (heterozygous).
75%
There is 50% that children will be of negative blood type if parents are heterozygous positive. 25% if one parent is homozygous and other heterozygous. 0% if both homozygous.
By the process of hybridization, breeders cross two genetically different organisms. The purpose is to have the best traits of both parents.
There are few possibilities. Those are 1.father with heterozygous A=AO & Mother with heterozygous B=BO 2.Father with heterozygous B=BO & Mother with heterozygous A=AO 3.Both the parents are with O blood group. If u have brothers or sisters if their blood groups r also O then the third one is the correct. Even it is applicable for Rh +ve or Rh -ve.
Yes, buy only if the parents are heterozygous for the trait and if the trait is dominant.
25%
Being born with six fingers is actually a dominant trait and the probability of the children would be 75% with six fingers and 25% with five fingers if both parents were heterozygous for that trait. If both parents were homozygous dominant for that trait then there is a 100% probability of the children being born with six fingers.
Both of the parents were heterozygous with the blonde hair allele, which is recessive. When there are two parents that are heterozygous, there is a 25% chance their offspring will get two of the recessive alleles. A punnett square can be useful when determining the different phenotypes and genotypes possible in offspring
