Midphalangeal hair (hair on top of the middlesegment of the fingers) is a common phenotypecaused by a dominant allele M. Homozygotes forthe recessive allele (mm) lack hair on the middlesegment of their fingers. Among 1000 families inwhich both parents had midphalangeal hair, 1853children showed the trait while 209 children did not.Explain this result

The part that is missing is where the traits for things like colorblindness and hemophilia exist. This meansthat if you have XY chromosomes, you are missing alleles on one of the chromosomes. So whatever alleleis on your X is expressed regardless of if being dominant or recessive. These X-Linked Traits have a specialway to note the alleles.X-Linked alleles use X and Y as their base and then the allele that notates the trait is in the top, rightcorner. For instance: Phenotype(appearance) Genotype(alleles) XY with Hemophilia XhY XX withouth Hemophilia XHXh Notice that the female has two X’s so has 2 alleles. She is not a hemophiliac, but is carrying the trait.That means she can pass the trait to her offspring.Why don’t you cross those two parents here and find the outcome:Parents:                                                             Offspring: Genotypes:Phenotypes:         Is there a chance of producing an XY offspring with hemophilia?

Having a widows peak is dominant W to not having one (ww)Having attached earlobes is a recessive trait (ee)- Jack and Jill are heterozygous for both traits.What's the probability of them having a child with a widow's peak and attachedearlobes?

Assume Mendelian inheritance laws apply, and a trait is either completely dominant or recessive. Еye color: Br – dominant brown bl – recessive blue Hair color Br" -- dominant brown bl" – recessive blonde A male with brown eyes and brown hair (genotype Br"Br"Br"bl") is planning on having a child with a female who has blue eyes and brown hair (genotype bl"bl*Br"bl"). A) Fill in all blanks (8 total to complete the two-trait Punnett Square 1). 2) Possible allelic combinations in male gametes 5) 6) 7) 8).

A mouse strain that has undergone inbreeding for many generations (e.b. >1000 generations) will be which of the following: O homozygous for recessive alleles at every locus O homozygous for dominant alleles at every locus O have a dominant allele at each locus, but does not have to be homozygous O may have a combination of heterozygous and homozygous loci O a mixture of dominant and recessive homozygous genotypes
