If the genotype is AaBb then there will be 4 gametes produced: AB, Ab, aB, ab.
Therefore the percentage of ab gametes is 25%
25%
Half of the gametes will contain the A allele, and half will contain the a allele.
If the male parent has genotype AS and the female parent has genotype AA what is the offspring?
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.
That depends entirely on the genotypes of the parents.
Aa=2 Bb=2 CC=1 dd=1 EE=1 2 x 2 x 1 x 1 x 1 = 4
Half of the gametes will contain the A allele, and half will contain the a allele.
A gamete is haploid (1N) so 'Aa' & 'AA' are diploid and during cell division (mitosis) gametes are formed and then 2 gametes merge together to make a diploid (think of sperm and egg, each is haploid or 1N, when fertilization occurs the egg and sperm form 1 cell that is 2N or diploid). So the possible gametes for 'Aa' would be 'A' & 'a' while for 'AA' the only gametes possible are 'A' If the question is asking what the possible gametes are for 'AaBB' the haploid (gamete) can be 'AB' or 'aB'
2^6 gametes. Every letterkombination (Aa etc) can give rise to two different gametes. A and a. These six letters can all be combined in different ways as: 2*2*2*2*2*2=2^6 combinations.
If the male parent has genotype AS and the female parent has genotype AA what is the offspring?
Two types: A heterozygous parent (Aa) and a homoygous recessive parent (aa) can produce phenotypically dominate and phenotpically recessive offspring (with 50% genotypes Aa and the other 50% aa). If the genes are co-dominate then the offspring can have blended traits and recessive traits phenotypically.
Only half of each parent's alleles are passed to their children. This means that parent 1 who is Aa at one gene locus will only pass A or a on to each offspring. Parent 2 may be AA, aa or Aa and will also only pass one allele on to each offspring.
Parent AA and Parent aa have children. All children are Aa Parent Aa and Parent Aa have children. 1AA:2Aa:1aa probability with each child. This is recombination of the most direct/simplest kind.
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.
If they're both homozygous (AA, AA): A is produced. If they're both heterozygous (Ai, Ai): A or O is produced. If one of them is heterozygous and the other not (Ai, AA): A is produced.
Principle of segregation
That depends entirely on the genotypes of the parents.
