Albinism is known to be due to an autosomal recessive mutation. The first child of a couple with normal skin pigmentation was an albino. What is the probability that their second child will also be an albino

At what temperature the blood is stored in bottles

In pea plants, red flowers $(R)$ are dominant over to white flowers $(r)$ and tall plants $(T)$ are dominant over to dwarf plants $(t)$. The table below shows the gametes and the possible offsprings produced in a dihybrid cross. The numbers $1$ to $16$ represent the genotypes of each individual cross $(e.g. 3 = RrTT)$

                $RT$      $Rt$     $rT$      $rt$

$RT$             $1$        $2$       $3$       $4$

$Rt$              $5$        $6$       $7$       $8$

$rT$              $9$        $10$     $11$     $12$

$rt$               $13$       $14$     $15$    $16$

If plant $7$ is crossed with plant $12$, then what proportion of the offsprings produced will be homozygous for both the recessive characters
