Description : ABO blood grouping is controlled by gene I which has three alleles and show co-dominance. There are six genotypes. How many phenotypes in all are possible? (a) Six (b) Three (c) Four (d) Five
Last Answer : (c) Four
Description : ABO blood groups in humans are controlled by the gene I. It has three alleles - IA, IB and i. Since there are three different alleles, six different genotypes are possible. How many phenotypes can occur? (a) Three (b) One (c) Four (d) Two
Description : 3. How many genotypes are possible in human ABO blood grouping a) 2 b) 4 c) 6 d) 8
Last Answer : c) 6
Description : 2) Person having genotypes IA IB would show the blood group as AB. This is because of – a)pleiotropy b)co-dominance c)segregation d)incomplete dominance
Last Answer : b)co-dominance
Description : A blue colour flower plant denoted by BB is cross bred with that of white colour flower plant denoted by bb. (a) State the colour of flower you would expect in their F1 generation plants. (b) What ... -pollinated? (c) State the expected ratio of the genotypes BB and Bb in the F2 progeny. -Biology
Last Answer : This is your Answer.
Description : In dogs wire hair (D) is dominant over smooth hair (d) . If two wire haired dogs produce a smooth haired pup , the genotypes of the parent?
Last Answer : Both parents are Dd. They express the dominant gene but carry the recessive one, so there's a 25% chance that the pup will express the recessive one. If either parent was DD, then it would be impossible to produce a pup that expresses the recessive gene.
Description : What are the possible genotypes of a Pea plant?
Last Answer : Either TT or Tt, where T stands for dominant gene for tallnessand t for recessive gene.
Description : In a dihybrid cross with genotypes JjQq and JJQq what is the probability of getting an offspring with genotype JJQQ?
Last Answer : Need answer
Description : How is it possible for two individuals to have the same phenotype but a different genotypes for a trait?
Last Answer : it is possible beccause you dont always need both
Description : How the genotypes RR and Rr result in the same phenotype?
Last Answer : 4
Description : If you were to get four different offspring from this cross list the different genotypes and the number of each genotype you would expect?
Last Answer : Feel Free to Answer
Description : What are the result of a cross between parents with genotypes Cc and cc?
Last Answer : The expected results are half Cc and half cc.
Description : What were Punnett squares developed to do to predict the probability of offspring phenotypes to predict the probability of offspring genotypes neither of the above?
Last Answer : What is the answer ?
Description : What genotypes would be considered hybrids?
Description : What are the possible genotypes of offspring in this cross?
Description : If you know the parents alleles for a trait how can you use a punnett square to predict the probable genotypes of the offspring?
Last Answer : So, if one parent is Aa (heterozygous) and the other parent isaa (homozygous recessive) the punnett square would look likethis:___|_A__|__a__a_|_Aa_|_aa__a_|_Aa_|_aa_The genotypes of the offspring 50% heterozygous and 50%homozygous recessive
Description : If a plant with the genotype PP is crossed with a plant with the genotyp pp what are the possible genotypes of the offspring?
Description : The polygenic genes show (a) different karyotypes (b) different genotypes (c) different phenotypes(d) none of these.
Last Answer : (c) different phenotypes
Description : In a cross between AABB × aabb, the ratio of F2 genotypes between AABB, AaBB, Aabb and aabb would be (a) 9 : 3 : 3 : 1 (b) 2 : 1 : 1 : 2 (c) 1 : 2 : 2 : 1 (d) 7 : 5 : 3 : 1.
Last Answer : (c) 1 : 2 : 2 : 1
Description : A human male produces sperms with the genotypes AB, Ab, aB and ab pertaining to two diallelic characters in equal proportions. What is the corresponding genotype of this person? (a) AaBB (b) AABb (c) AABB (d) AaBb
Last Answer : (d) AaBb
Description : Test cross involves (a) crossing between two genotypes with dominant trait (b) crossing between two genotypes with recessive trait (c) crossing between two F1 hybrids (d) crossing the F1 hybrid with a double recessive genotype.
Last Answer : (d) crossing the F1 hybrid with a double recessive genotype.
Description : Test cross in plants or in Drosophila involves crossing (a) between two genotypes with recessive trait (b) between two F1 hybrids (c) the F1 hybrid with a double recessive genotype (d) between two genotypes with dominant trait.
Last Answer : (c) the F1 hybrid with a double recessive genotype
Description : 4) In the F2 generation of a Mendelian dihybrid cross the number of phenotypes and genotypes are: (a) Phenotypes-4,genotypes-16 (b) ) Phenotypes-9,genotypes-4 (c) ) Phenotypes-4,genotypes-8 (d) ) Phenotypes-4,genotypes-9
Last Answer : 4.d Phenotypes-4,genotypes-9
Description : What does blood type rh stand for?
Last Answer : Rh factor is named after the Rhesus monkey which was the source of testing. It refers to the plus or minus after one's blood type which determines compatibility.
