The likelihood that the first two offspring of the cross will have congenital analgesia would be 1/16
<h2>Autosomal Recessive Traits</h2>
For autosomal recessive traits, two recessive alleles are needed for the trait to manifest while one recessive allele means heterozygosity.
In this case, let us assume that congenital analgesia is represented by the allele b; heterozygous individuals will, thus, be Bb.
Bb x Bb
BB Bb Bb bb
Probability of producing unaffected offspring = 3/4
Probability of producing affected offspring = 1/4
Likelihood of the first two offspring having congenital analgesia = probability of first having congenital analgesia and the second having congenital analgesia
= 1/4 x 1/4
= 1/16

Answer:
Invertebrates are the organisms in which backbone or vertebral column is absent.
The three macroinvertebrate categories are annelids, mollusks and arthropods.
Annelids are the organisms having segmented body. They are found in moist places. Examples are leeches and earth worms.
Mollusks are the organisms which are enclosed in a calcium carbonate shell. Examples are snails and slugs.
arthropods are the invertebrates which have segmented body and jointed appendages. Examples are insects and crustaceans etc.
The answer is 4. Mitochondria
Answer:
4 grams
Explanation:
If in an experiment, we have 4g of reactants, the mass of the products will also be 4g.
This is in compliance with the law of conservation of mass in a chemical reaction.
According to this law,
"in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".
If:
A + B → C
4g 4g
mass of A and B must be equal to the mass of the product according to the law of conservation of mass.
