What will determine the genotype of an organism?
The alleles that are passed from parents to offspring
Can a child's genotype be different from that of both parents?
A genotype is decided from two alleles. One of these alleles comes from the father, and one comes from the mother. Thus it should be clear that the genotype can be different from both parents. For instance, suppose the father has genotype AA, and the mother has genotype aa. In this case, the child will have genotype Aa, which neither parent has.
How do you identify the genotype?
normal sexual cross pollination - each parent plant contributes traits from its genotype (which are expressed as the phenotype)
How do you identify a homozygous ressive genotype?
See if the parent organisms have the same trait as the offspring. Those traits have to be recessive.
If one parent has the genotype Cc for hair color and the other parent has the genotype cc what percentage of the offspring will have the recessive genotype for hair color?
25% of the offspring will have the recessive genotype for hair colour.

What are alleles and what are the two forms?
They are traits that are passed on from parent to offspring. There are also two types of alleles; Dominant and recessive.

Different forms of gene?
Alleles are the different types of genes.
What is a genotype for the first parent?
well, genotype can be the two alleles for any given gene, while phenotype is the actual (observable) expression of that gene.
Can parent with as and AA genotype give birth to ac genotype?
If the male parent has genotype AS and the female parent has genotype AA what is the offspring?
If the male parent has the genotype AAA and the female parent has the genotype AAA offsprings genotype will be?
The offspring's genotype will be AA. Both parents are homozygous dominant, AA, having only dominant alleles to pass on to their offspring. So each parent can pass on only the dominant allele (A) to its offspring. So the offspring will also be homozygous dominant, AA.
How do you identify a homozygous ressive genotype?
See if the parent organisms have the same trait as the offspring. Those traits have to be recessive.
What is the genotype of a child if the mother is homozygous for the dominant trait and the father is homozygous for the recessive trait?
The dominant parent is most likely homozygous dominant, and the recessive parent has only the homozygous genotype. So the dominant parent can pass on only dominant alleles for this trait, and the recessive parent can pass on only recessive alleles for this trait. So all of the offspring would be heterozygous and have the dominant phenotype.
If about 50 percent of the offspring have the dominant phenotype and 50 percent have the recessive phenotype what are the genotype of the parents?
If the phenotype is recessive then the genotype must be dd.
What do the letters along the top and the bottom of the punnett square represent?
The letters to the left are the two alleles (the genotype) of one parent and the letters above is the other parents genotype. If the letter is capital it means the trait is dominant and if the letter is lowercase, it's recessive
