In mice, the allele for black fur is dominant to the allele for brown fur. a male homozygous black mouse is crossed with a femal
e brown mouse, and the f1 offspring are allowed to breed. what proportion of the black mice in the f2 offspring do you predict will be homozygous? ( enter the number only without the percent sign. for example, enter 100% as 100 and enter 12.5% as 12.5 )
The parental cross is true-breeding because both the male and the female are homo zygotes, so: BBx bb
The F1 generation will be all black heterozygote: Bb The F2 generation will be between mice of the F1 generation and they all have the same genotype:Bb xBb In this cross it would result in: 1/4 of the plants being black homozygote-BB 25% 2/4 of the plants being black heterozygote- Bb- 50% 1/4 of the plants being brown homozygote- bb- 25% answer: 25%+25%=50% are homozygotes
<span>Well, one is hydrophobic and one is hydrophilic so that causes a big effect in the way that the amino acids are grouped together or spread out</span>
The process that lead to the formation of the distorted, wavy patterns found in metamorphic rock is regional metamorphism(as heat and pressure increases, minerals become segregated into bands).
