If you mix the Pattersonase gene sequence with EcoRI, how many
miv72 [106K]

Answer:One EcoRI site can be found in 4096 bp.As EcoRI can not cut a sequence if it is not complete, so 732421 recognition sites in human genome can be found. As you know human genome is linear genome, and when you digest it with Restriction Endonuclease having one recognition site, it always gives two fragments.

n cattle, an autosomal mutation called Dexter produces calves with short stature and short limbs. Embryos that are homozygous fo
timofeeve [1]

Answer:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

Explanation:

Dexter is deleterious in homozygous condition, hence, phenotypes are heterozygous.

Roan are also heterozygous.

If dexter allele is represented by D, non dexter individuals will be DD dexter individuals will have the genotype Dd.

If colour in cattle is represented by R, red individuals will be RR, white will be rr, then roan colour will be Rr.

Hence, roan dexter cow and roan dexter bull will both have DdRr genotypes.

Crossing the two:    DdRr   x   DdRr

Progeny:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

<em>Others that are either aborted or stillbirths include:</em>

<em>1 ddRR </em>

<em>2 ddRr </em>

<em>1 ddrr</em>
