There are .................... of AMINO ACIDS which join together ........................
Amino acids are the building units of protein. There are basically twenty different types of amino acids which are divided into two classes of essential and non essential amino acids based on their requirements in human nutrition. These amino acids joined together in different manner to form different types of proteins.

Assume that a cross is made between AaBb and aabb plants and that the offspring occur in the following numbers: 106 AaBb, 48 Aab
Elenna [48]

Answer:

linkage with approximately 33 map units between the two gene loci

Explanation:

If two genes are not linked, number of recombinants and parental offspring will be equal. Here it is clearly visible that recombinants are less than parental offspring hence the genes are linked. Given, the offspring are in following numbers:

AaBb = 106 = Parental

aabb = 94 = Parental

Aabb = 48 = Recombinant

aaBb = 52 = Recombinant

Recombination frequency = (Number of recombinants/ Total progeny) * 100 = (100/300) * 100 = 33.33 %

1% recombination frequency= 1 map unit of distance between the two gene loci. So here the distance between the two gene loci is approximately 33 map units.

Hence, these results are consistent with linkage with approximately 33 map units between the two gene loci

kifflom [539]

Answer:

D.Mendel's law of independent assortment is being violated.

Explanation:

According to Mendel in his law of independent assortment, the allele of one gene gets sorted into gametes independently of the allele of another gene. He discovered this when he performed a cross involving two characters i.e. dihybrid cross, which he obtained a F2 phenotypic ratio of 9:3:3:1. This ratio is only possible if each allele of each gene is represented in each gamete i.e. a dominant allele of the first gene is equally likely possible to be contained with a dominant or recessive allele in the second gene.

If this occurs according to the Mendel's law of independent assortment, a total of four possible combinations of gametes should be produced by each parent organism. When this 4 gametes are crossed in a punnet square, a total of 16 offsprings will be possible.

However, in this case, a total of 12 offsprings were produced, depicting that the alleles did not separate independently of one another to produce four possible gametes.
