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:
Due to newly formed land.
Explanation:
Surtsey provided ideal conditions for studying primary succession because due to volcanic eruption all the vegetation and living organisms are destroyed from the surface and the land has no vegetation. Primary succession only occurs when the land is colonized for the first time after the formation of land due to natural disaster such as volcanic eruption etc. So we can say that Surtsey provided the conditions for observing primary succession.
Answer:
If it is a gene mutation then it is during the S phase, and if it is a chromosome mutation, then during metaphase or anaphase.
