Answer #1

Let's consider that -

\mu MT ^-/- = tt

And FcRn^+/- = Rr

Now cross between two mouse- Fo

tt Rr × tt Rr

so tt×tt

Gametes - tt tt tt tt

Rr × Rr

​​​​​​RR Rr Rr rr

This means that tt here stands for \mu MT ^ -/-

So all the F1 pups will have genotype- \mu MT ^-/-

And RR means- FcRn ^ +/+

Rr means - FcRn ^+/-

rr means - FcRn ^ -/-

So F1 pups Genotype will be \mu MT ^-/- FcRn ^ +/+, +/- ,-/-

Punnett square- is shown in the figure. The gametes formed by \mu MT -/- FcRn ^+/- is similar to the other mouse having same genotype. i unit Fc Rn+1- gametis (UMT FcRnt Cum - Fern) Cu MT- Fehnt) UMT Fehn now unt-t-Fehn thx u MTt Flytt2 UMT FcRnt 2 Unt-Ferr 2 UMT-Fornt umrl Fernt unT/ Fehnt/- 2 UMT FORM umT/FcRytt umt-1-FcRnt- anche X2if you like my answer please upvote.

Continuing on with the example in question 1, predict the phenotype corresponding to each offspring genotype if: Gene A is governed by complete dominance and gene B by incomplete dominance. Possible phenotypes for gene A are tall (dominant phenotype) and short (recessive phenotype), and for gene, B is...

    (Q21-25) We have the following three sets of mouse breeding experiments. The table summarizes the number of each category of the F2 progeny. These breeding results were obtained in a similar fashion as shown in the lecture, starting from two pure-bred homozygous lines as the Parental stage, which were followed by the heterozygous F1. The subsequent F1 was testcrossed with the breeding partners with homozygous recessive alleles. Wild-type alleles are indicated with +, and the mutant alleles without + are...
